What is your biggest question about growing cannabis?

[tyler_ hobbyist]

Very nice article nebula I really enjoyed it. Besides genetics and tempature there must be more ways to get different colors out of ur buds. Theoretically u have a strain ths geneticly supose to turn a certain colors how can u inhance that besides tempature? I know purple maxx the nutrient starts to turn stocks and stems purple so far my candy cane photos started turning purple after useing that product and I dnt thinks 3 candy cane plants are a pheno and I dnt beleave candy cane has any purple genes in it. After trying this product it got me very courious about all the other colors out there that might be able to be brought out by a chemicle reaction. I dnt know how well puprle maxx works for buds yet but I'm gunna give it a try the 1st pic with the stock and nute burnt leaves that was my fault.

[growmore]

@tyler_hobbyist If the plant you are growing does not have the genetic phenotype to turn a particular colour then you will not see that colour. If you add something to change a plant to a certain colour then all you are really doing is applying a colouring agent. Think about it the same as with milk. Milk is naturally white but if I add food colouring to it Then you can get any colour you want, but you have only changed its appearance and nothing else

[tyler_ hobbyist]

That's a gd theroy growmore but dyes and coloring agents don't work in that way with canabis u can't just add it to the water or cut the stem and add the coloring the plant doesn't obsorb the coloring. Also the purplemaxx nutrient is a clear liquid.

[tyler_ hobbyist]

Thank you nebula if u end up comeing across any info on this topic I would greatly appreciate it, if u shared it with me

[jacobsonwyatt41]

Marijuana is the natural discussion piece that just won't leave. Responses to it run a wild range: It's the malevolent weed or a wellspring of future state charge income and entrepreneurial resourcefulness. Or, on the other hand it's the main way left to flexibility from agony for a few people, and columnists ought to expound on it with a similar reality that they accord pulse medication.

[Marley]

Is it true that you can use a green light during the dark period as to not upset the plant's "sleep/awake" cycle? I mean for short periods of poking around the tent, not on all the time.

[9fingerleafs]

Yes. But I've heard green CFls make light we perceive as green but it emits other wavelength protons as well. So if you want to get a green light get a led light with specific light spectrum so you can be sure it doesn't mess with the plant

[NebulaHaze]

Exactly what 9fingerleafs said! They sell lights specially for checking on plants at night without interrupting their photoperiod.

[StoneyTony]

Just ordered one of these lights. Should be here next week. Seems like it'll be nice to have just in case I need to check on something

[Canuck147]

What to do with the 'sugar leaves'?

[tyler_ hobbyist]

U could aslo make oil with butane or everclear. Butane method is better lol u could also make shadder if u have the cooker if not the cookers are very exspencive

[StoneyTony]

All the above and more! LOL

[NebulaHaze]

I second dry ice hash!

[CCisme]

Ok how do you make high thc and high cbd oil. Does cbd come out in say a coconut oil extraction? Or after making dry ice kief do/can you go back and run that through oil to remove cbd? Or am I misunderstanding the process (most likly option) I also have my oldest daughter at 18 wants to try a 1-1 for her adhd and anxiety, Neither of us wants her smoking lol so Edibles or caps.

thank you I love this thread!

[Chef]

Through my readings and experience the oils and resins that are extrected through making butter, and oils is that it binds with the fat molecule, hence a fat soluble drug. The Oils and butter are ecellent for baking. Just sustitute for reg butter in recipe.
I made RSO (very different from butter) and was very successful and yileded about 3cc's from about 1/2 of prime trim. I did 2 evaporations with everclear as my medium, both cooked down for about 5 min a time. I read that a third and fourth pass would be obsolete. Your daughter is 18, an adult...She can take your advice but ultimatley its her decision.

Hope this helps

[CCisme]

Yeah rso is something Im intrested in trying but saving to make til the lupus gets way worse. Ive been doing coconut oil cannacaps for 2 ish years but was just unsure about the cbd aspect, and honestly until I started growing couldnt have told you the difference between indica and sativa lol Let alone which strains would have cbd
So thoughts on if you removed everything with dry ice could you then make a stronger non pshyco active cbd oil?

[StoneyTony]

Interesting question. I've never heard of anyone being able to seperate THC from CBDs. As far as I understand you get what the strain has been bred with. If looking for a high CBD strain try Charlotte's Web, Nebula CBD, Catatonic CBD, or Supreme CBD Durban to name a few.

[NebulaHaze]

tyler_ hobbyist I've done some research into what makes flowers turn the colors they do, and I found an interesting article about how a group of scientists were able to alter the genes of roses in order to produce a rose with blue hues (which they never naturally show in the wild): https://academic.oup.com/pcp/article...d-Biosynthetic

Apparently there's tons of genes that we know of that affect flower color. One of the pigments that gives a blue or purple hue is called an Anthocyanin. Anthocyanins are already located in the plant, but the idea is you want more Anthocyanin than chlorophyll (which makes buds or leaves appear green).

So in the experiment they altered the genes of the rose to express more of a blue color by getting the roses to produce more delphinidin which turns into the pigment Anthocyanin. They did this by altering a gene so it produced more of the Flavonoid 3',5'-hydroxylase (often referred to as F3'5'H).

Producing more of the flavonoid F3'5'H caused the plant to produce more delphinin, which turned into red-blue Anthocyanin. Anthocyanin turns blue if it's exposed to a high-pH environment in the plant tissue.

It makes me wonder if giving the flavonoid F3'5'H directly to the plant (either through the roots or foliar spray) may alter the color of the flowers by increasing the amount of delphinidin being produced. Or maybe you could even give the plant delphinidin directly.

I also found out that the pH of the flowers or plant tissue had an effect on the final color, which I found very interesting. Apparently delphinidin is a natural pH indicator, sort of like the drops we use to test pH. If it's in a basic/alkaline environment it turns blue, and in an acidic environment it turns red. I have no idea what changes the pH within the flower tissue, and I doubt it's as direct as changing the pH of the roots, but you need both an acidic flower environment and plenty delphinidin in order to get the blue/purple to show.

Just as a side note, I tried to find out what's in Purple Maxx (which you were saying turned your stems purple). I found this Youtube video from a nutrient supplier, which says Purple Maxx has two active ingredients: Methyl jasmonate and Triacontanol. It also has Potassium Hydroxide listed as an ingredient on the label.

[NebulaHaze]

Wow Newf, I did NOT know that! That's very interesting to me! I will check it out!

@tyler_hobbyist I wish I knew or I'd be buying them too! If you find a good source, please tell me! I'll also be looking and let you know if I find anything!

[tyler_ hobbyist]

I will forsure thank u nebula

[tyler_ hobbyist]

Another way to help turn hydragas blue is aluminum sulfate I tryed it with some of my plants and it didn't seem to do anything with autos ill have to try it with a photo sometime

[NebulaHaze]

thank you I love this thread!

I understand it the way StoneyTony described. Since both THC and CBD are soluble in most of the same things as each other (alcohol, oil, solvents, etc), I've never heard of a way that works at home to extract them separately. At least on a hobby scale, it seems like the main way to get high-CBD concentrates or edibles is by starting with high-CBD cannabis, and vice versa for high THC products. So, people usually grow separate high-THC and high-CBD strains if they want to be able to dose THC and CBD separately. From what I understand you need expensive equipment to isolate THC and CBD from each other.

[CCisme]

NebulaHaze Thanks I was thinking that, then stumbled upon another series of articles meant to confuse i think lolol. So a dry ice wash would contain the thc and cbd in a strain high in both? Sorry I ask a lot of questions in weird hard to understand ways. lol That was my orginal plan was to grow a 1-1 or higher for her, so I'll just go back to that.

[NebulaHaze]

Yes, you've got it exactly! If your weed has high amounts of THC and CBD, your dry ice hash will also be high in both THC and CBD.

THC and CBD are both cannabinoids, which are a class of substances found both naturally in the cannabis plant as well as in the human body. Most cannabinoids tend to be soluble (bind to) the same materials (oil, alcohol and solvents), and are chemically a similar size (so you couldn't sift one out, for example), which makes it difficult to find ways to separate them.

[CCisme]

Thank You!!

[NebulaHaze]

NebulaHaze , what micron bag do you typically use for the dry ice hash?

StoneyTony I'll usually go with just the 160 Micron bag, or possibly the 73 then the 160 if I want a separate pure pile.

The 25 Micron has the tiniest holes, which are the exact size of a trichome head. Because it only lets pure trichomes through, it gives you the purest stuff. But at least in practice I've found it's not that different than the purity you'd get from the 25 Micron bag, and you'll get far better yields with 73 Micron bag. They'll both give you a gorgeous gold colored hash.

If you want something more flavorful, the 120 or 160 Micron bags are good because they capture more of the green stuff. I feel like the effects are different, as well. I've found that above 160 Micron it doesn't really seem to add a whole lot to potency, but does incorporate a lot more inert green plant matter.

Here's a picture. The first one (left) shows the 73 Micron extract. Then I took the same bud and put it through the 160 (middle) and then I took what's left and made 220 (right). The 73 and 160 were good, but the 220 was meh. Now I just do the 120 (more pure) or 160 (more yield) Micron bags by themselves. I toss the rest after the one extraction. After doing it the first time for testing, I feel like there isn't a whole lot of benefit to putting the same cannabis through multiple bags unless you were just really trying to maximize yields.



Closeup of 73 Micron hash (most pure - just trichomes)



Closeup of 160 Micron Extract (more green matter, but still very high quality)



This is the 220 Micron dry ice hash



I personally thought the 220 Micron hash was just okay. Admittedly everything lower than 160 Micron had already been sifted out, but this didn't seem to have much potency on its own. It was extremely smelly and had a strong green taste. We ended up not using most of it.

Since then I've stuck with 160 Micron bags and smaller.

[OzBud]

In the video on your tutorial your dry ice was in chunks? Dry ice isn't easily available here in small quantities, would dry ice in pellet form work too, or would it sublime too quickly?
Roughly how long does yours take to fully sublime?

[NebulaHaze]

It seems like it should work. If anything I could see it working better with small pieces because the cold would be spread out more throughout the cannabis. I think we used 3 lbs of dry ice for 3 ounces of dried bud and we were able to put it through the 3 bags and there was still some dry ice left over at the end. If you were using smaller pieces, I bet it would sublimate more quickly. You can see what looks like fog coming off of it, and handling it and shaking it around causes it to sublimate pretty fast! As long as it's not too expensive, it can't hurt to get some extra just in case. Any left over dry ice can be put outside at night and it'll be gone by morning.

And very importantly, always make sure your cannabis is completely dry first!

[CCisme]

I only had a 190 micron bag from my magic butter machine. We did 2 two minute runs and got 10g gold and 6g green from an oz. Honestly I can not thank you enough, I needed this to last as long as I can go. ❤

[r3m1]

i have a few big questions actually!

1. how should a feed schedule be for coco (ex. fed/water/fed or water/fed/water also with stump tea fed/water/stump or fed/stump/fed or fed/stump/water/fed)
2. PPM i understand how it works etc but ppm ranges ive heard as high as 1700ppms but normally 1200-1400 (this is what i would like to understand on how the range effects the plant)
3. what is the best method on keeping track of what plants have been fed or watered/ rotations or turning.
4. anyone ready to add in as a grower the tracking system that most states put in place? any programs that could be suggested and great to track plants with?
5. last question promise, best time and amount of co2 being used (roughly no understanding of c02 and how if effects growth, next project)

[LuckyAcres]

Hey r3,
3. I use the google app sheets to keep track of everything, can be shared with others if needed.
4. Oregon health department runs the tracking system here and they have a software all set up online for that, just go to the page and fill in numbers.

[StoneyTony]

Hi R3M1. Here is a pdf schedule that Nubula made for coco coir. Most everyone, myself included, have had great success with it. Just print it and stick it by your mixing area: http://www.growweedeasy.com/sites/gr...s-schedule.pdf

[bobsakamoto]

r3m1 over on page 2 of this thread GreenArmadillo asked about EC and ppms and NebulaHaze gave a really good, informative answer

Thank you, Nebula, for starting this thread. i have learned SO MUCH from it!

[BuddMarsh]

I have another question :-) What is the trigger for an auto to start to flower? Is it just time? Is it number of nodes the plant has formed? What phase the moon is in?

[Sean Winchester]

It's just time. it will automatically start flowering under any light schedule

[Sean Winchester]

Finally I know an answer. all this reading paid off

[StoneyTony]

Like Sean said. Usually at about week 3.

[NebulaHaze]

i have a few big questions actually!

1. how should a feed schedule be for coco (ex. fed/water/fed or water/fed/water also with stump tea fed/water/stump or fed/stump/fed or fed/stump/water/fed)
2. PPM i understand how it works etc but ppm ranges ive heard as high as 1700ppms but normally 1200-1400 (this is what i would like to understand on how the range effects the plant)

1. This is the one I use: http://www.growweedeasy.com/sites/gr...s-schedule.pdf
2. It really depends on a lot of things. Lots of things add PPM, but not all of them will burn your plant. Imagine if I got dirt from outside and mixed it with water. It could measure as having 3000 PPM of "stuff" but it wouldn't have many nutrients in it so your plant could still get nutrient deficiencies. But with mineral nutrient sources, you can add 400 PPM and it will burn your plants. Say I start with 200 PPM water, and I add 400 PPM of mineral nutrients. If I add any more of that type of nutrients it will kill the plant, even though the total PPM is only 600. But I could still add worm castings or Silica, which would increase the PPM but are much less "powerful" with lower levels of things that can burn the plant. I've heard people talk about very high PPM numbers, and I assume they are using supplements which add lots of PPM to the water without adding actual nutrients that can burn your plant. All I can say is that, at least in hydro, I've never had my PPM higher than 600 or 700 without burning the plants. It seems like the lower the levels of plant nutrients in each additive, the more PPM of that bottle you could add. If in doubt, I highly recommend contacting the nutrient company through their website and ask about optimum PPMs with their nutrient system. I've found most nutrient companies get back to you really quickly and have helpful insider information!
3. Every grower has their own method but at least for me I have a notebook that I hang from the wall of my grow room with a pencil attached, and I keep all my notes, dates and updates in that.
4. I'm not familiar with any type of state-sponsored tracking system, do you have a link?
5. CO2 is effective at getting faster vegetative growth when your plant is getting more light than it can use, for example under a 1000W HPS. Adding more CO2 to the air helps the plant use some of that extra light. In order for CO2 supplementation to be effective, you want to have relatively high concentrations of CO2 in the grow space. As far as when to use it, you only get benefits when the lights are on because the way it works is by helping the plant do photosynthesis. Without photosynthesis, extra CO2 doesn't really help, so there's no point in adding it at night

[r3m1]

thanks nebula this cleared alot of questions on ppm and Co2 ill check into the schedule here in a few. Ill also pull some info because as of dec 2017 seed to sale has to be done using a tracking system along with cameras.. this will be the bigger pain in my ass but worth it. ill see is i can find a few to post thanks again.

https://www.biotrack.com/cultivation/ here is a link to non state ran tracking systems for seed to sale to dispos and inventory

[NebulaHaze]

I have another question :-) What is the trigger for an auto to start to flower? Is it just time? Is it number of nodes the plant has formed? What phase the moon is in?

This is a really great question! So mainly, it seems to be time. It seems like most auto-flowering plants start making buds around 3-4 weeks from seed. However, other things have an effect, so it's obviously more than just that. For example, if an auto-flowering plant is very stunted in the first few weeks of life, it usually takes a little longer to start flowering. So it sort of seems like the plant needs to be a certain size, or have at least a few nodes, before it will start flowering.

Similarly, if you put a photoperiod plant under a 12/12 light schedule from the beginning of its life, it won't start flowering until week 3-4, just like an auto-flower. Also, photoperiod male and female plants start putting out pre-flowers (smaller version of adult flowers) when they're around that same age. That seems to be the time when the plant fully "decides" its gender. So it almost seems like the plant does require some sort of minimum time of ~3 weeks before it will start flowering. I don't think I've seen a seedling of any strain start flowering much sooner than that in any situation.

Another thing that may affects auto-flowering schedules is the quality of light. I'm not sure what exactly causes it, but sometimes with certain LED grow lights, you'll get an auto-flowering strain that takes several weeks longer to finish flowering than that same strain being grown under fluorescent or HPS lights in the same conditions. It seems almost random, but I've spoken with a half dozen growers who have run into the slow-to-develop problem with auto-flowering strains under LED growth lights. Though there's tons of growers and models of LED that don't seem to have that problem, so it's hard to know if it's about the model of LED or the strain.

There are many non-cannabis types of plants that automatically start flowering after a certain time. In some cases, the temperature or humidity can cause them to take longer or shorter to start making flowers. For example, some plants need warm and humid temperatures before they start flowering. So it makes you wonder if cooler temps may be slowing down the flowering of auto-flowering strains. In fact, if LED grow lights are cool enough that they aren't keeping the grow space warm, maybe that's a factor in why some people have trouble with flowering autos under LEDs?

Another interesting thing to note is that if you have an auto-flowering plant that's auto'ed but is taking forever, you can give it a 12/12 light period to "hurry it along." So it seems like even the auto-flowering strains are somewhat responsive to light periods, even if it doesn't NEED a short-day to start flowering.

[BuddMarsh]

Thank-you again for the time you took to answer my question. You also gave me the answer I was hoping for ,that time is not the only factor, if it was I think I would have the world's smallest flowering plant. She has had a rough two weeks and the second set of true leaves are still a single finger and very small, but I love her just the same.

[Jibblerjoe]

I had a seedsman white widow ,it didn't flower till around 2 months, I started a second and it Auto ed in the normal 3 to 4 wks. The late bloomer now has 14 in Colas. Grown under hps.

[Jibblerjoe]

Nebula can I ask what your current set up for growing?

[NebulaHaze]

This is the big setup that's sort of our main producer: http://www.growweedeasy.com/growing-...-shopping-list

We recently moved, but I plan on putting my second setup back up again soon: http://www.growweedeasy.com/growing-...-shopping-list I'm most likely going to switch out a 250W HPS for a 315 LEC just to test them out. Lots of people in this forum have been having great results with them!
