What is your biggest question about growing cannabis?

[alltatup]

Here's my biggest question of the moment: Is there any difference between leaf and bud trichomes other than density on buds?

Nevermind: I found the answer here.

New grow...1st grow; the seeds germinated on Aug 11 2018 and were placed in rapid rooters to develop.about August 20 they were planted in 3 gallon fox farm ocean floor soil and started feeding the fox farm trio. So far it is almost 6 weeks and all appears well with 2-1000 led light 36”-42”off the canopy and bending training . Amazed that in 6-8 hours they are fully curved back looking at the ceiling. 18/6 light schedule All seems text book.

i can leave them in veg, no auto here but wonder, since I am the sun, moon and stars to these ladies, I’m wondering how long and what benefit comes from long veg periods besides stem and leaf growth. The overall height is currently 20” on the blueberry kush and 18” on the velvet cheese . They are both equally wide about 18” 4- plants. Some of the fan leaves are bigger than my hands..room temp is 75, humidity is 56, co2 ranges 850 to 1140. Plants were topped two weeks ago and new growth is there and in place.

i think my question will be, when would be a recommend time after seed, to convert the lighting schedule to 12/12 and coax them into flowering? And then, keep an approximate future date for a possible harvest .
I am considering going to the 3200k 315W LEC ceramic metal halide for the flowering portion...vented reflector out of the room for heat assist.
thanks...Farmall

Hi Farmall, the longer in veg = the bigger the plant, of course. Depends on how much head room you have for them to stretch after you switch to 12/12...

[Farmall]

Just came back from checking them out after reading your post. So far, the pot is 16” tall and the plant is 16-18” so I have a Total of near 34” out of 80” to the bottom of the glass shield on the 315w vented lec light when it goes to flower. So this light will be 46”of space to the top cola when it grows. All lighting at this time has been from 2. 1200watt phlizon led for 2 pots each....I have LST these very bushy plants and topped them 3 weeks ago and all following text book growth pattern 18/6 schedule working. In this space at the warehouse, the co2 levels rarely drop below 900 and today I watched 1240 for several hours. Anxious to move on but you know that wine ad...’we will sell no wine before it’s time’

after All the work ...ain’t changing before its time too. I don’t mine long veg, just watching and waiting as we all seem to do.does another 3-4 weeks of veg seem too long? That would be 9 weeks since germination. Appreciate all thoughts...

[alltatup]

If you're going for monster plants, keep vegging!! ;-} I wish I had the headroom to veg longer, but I use grow boxes. I'm good vegging for between 4-6 weeks (depending on what the avg. stretch is for each strain).

[Farmall]

Currently involved in two processes; soil and hydro. The soil is ready for the text book photos... the hydro is pretty good but not what I’ve seen here. They are stretchy, have some nice topped growth but also some thin nothing sprouting at the bottoms near the first node. I’m tempted to prune that growth off. It does not seem like it can amount to anything. Switched to 12/12 4 days ago mostly because the soil is ready, hydro...I just want it to go into flower and finish things off. Probably need two grow areas separate from each other in this case.

the hydro had some issues I have not identified properly like a few spots mid leaf in the lower nodes, fine looking from node 2-5. Leaf curl upwards only on the edges...again nodes 2-4. Sparse growth between nodes like maybe 4-5 “ of stem then a node. A few giant fan leaves maybe 9” across at node 2 on 2 separate plants, they shade anything below them but they are node 2 level. I need to find if my trouble is nutes, pH, temp, or lighting. I have made routine pH down adjustment to 5.9-6.1. Using the GH trio with hydro-guard and cal-mag. My LEDs are 1000 w and cover 3 plants each. I know about leaf burn so as a test, since I’m not happy with these, was to measure temp and humidity at the top of the canopy. I get 74.7 and a humidity of 61%. Have 2 21” fans oscillating and try not to direct the flow directly at them .. 1 for hydro, 1 for soil at low speed but still a bit of a breeze.

nutes changed every Week and now measures about 760 ppm and ph of 5.9using a continuous top feed with each in its own 5 gallon bucket with water level at 3 gallon mark, about 1 inch below the net pot. Air stone for each bucket and 3 air stones in the reservoir. During the first 2 weeks I did notice and cleaned, a tan color foam in the 20 gallon reservoir... not sure of what it was but having used protein skimmers in marine aquariums, it must have been some form of dissolved organic material. No smell ever.

Anyone care to offer any opinions. Thanks in advance

[alltatup]

I get some muck that builds up in my reservoir, but I think it's the Great White mychorizae I use. My roots get stained as well from the nutes, but I don't worry if there's no root rot.

The hydro plant sounds like a Sativa-dominant... no?

[Farmall]

No, they are not Sativa... Indica hybrid but they had grown like very tall Sativas

I hope this is the right place to post this question...?



Hello all. First time poster and grower here with a beginner question. I've been reading a lot here and am so glad such a wonderful resource of knowledge exists to share with newbs.

Using a 3x3 tent setup, with seedlings in solo cups and moving into fabric pots eventually.

I picked up medium called 'potting soil' at a local farm/garden place. I'm at the point of being ready to start feeding my plants and I am a little confused over the medium being soil or soil-less medium, and which General Hydroponics nutrient system to use.

It's very light material (and I added a little perlite to the mix too). Water does pass through the solo cups with medium in them.

I think it's a soil-less medium?

I picked up the GH Go Box (when I was putting together my supplies at the outset) but now I am wondering if I should be using the GH Flora Trio instead? (more suited to my medium)?

Any advice would be appreciated.

Retodd is completely correct, except the part about me being a master, I ain't a master at nothin, even my wife says I ain't a master at cuddling up, lol.
Starting with good soil is 95percent of good growing MJ.
I use Mississippi Delta soil, with lots of perlite added in it. Every shovel full has at least 20-25 red wigglers in it..
But good luck with your grow.

[Retodd]

I’m so used to outdoor...I said vermiculite when I meant perlite...lmao

[oldjarhead100]

@DASS I disagree with you. You sir are a Master at staying alive and growing Autos lol

[stookin]

Thank you for the replies!!

No timed release nutrients. It's just a no-brand bag packaged for the supply store. It's certainly not the same weight as soil from my outdoor garden, but I'm not sure if it'll pack down into "mud" after more water settles the material. They've only had limited water through the cups so far (less than 2 weeks old).

Ack, can't see how to reply on comments above (yet... )

What is the best way to rid your plants of spider mites when you are 4 weeks into flower with plants that finish flower in 10 weeks

[Retodd]

You can use a mix of alcohol and water and spray them. My friend PaganRich had a bad problem with them on his last grow. Maybe he’ll chime in. I’ve heard of castile soap and water too, but I have never personally ever had to deal with them.

[PaganRich]

Thanks for the shout Retodd mate. Peycke I feel your pain...they are bastards of the highest order, extremely difficult to keep under control, ruin plants and your whole day, lower yields, etc, etc. That`s the bad news. Good news is, they can be `managed`. I use a rotating selection of either, Neem oil, insecticidal soaps, SM-90, alcohol and water and now a pesticide whilst vegging. I run a perpetual harvest for 8 months of the year. I smoke a lot, build up supplies then shut down in the hot months. This year I picked them up early and have lost at least one poss two plants as well as lower yields. Yet, it`s when you see them happily spinning webs on your buds that you want to get a sledge hammer out and pound the little sods into the floor-repeatedly.
Anyway, my advice, hit them with the heavy stuff in veg, pesticides, insecticides, neem oil as there`s no buds. Then flowering I rotate the options as they build resistance and I paint the leaves to try and coat the eggs with neem or soap. Every bloody leaf I do-sigh. For buds, alcohol and water though they do get used to that. It is an unrelenting battle but you can keep their numbers down with robust and regular treatments. Also, beware of cross comtamination between rooms, tents, etc. They can be beaten but realistically, you will need to take a break to allow any unhatched to hatch and die. Best time to do this is hot weather which will make them come out to party. Sorry it appears bleak but you really have to dig deep not to get totally fed-up...I`m already at that point Also, watch out for what some folk claim to work, bleach and water submerged for 6 hrs was one barking idea someone was trying. Just don`t get anything on the buds and don`t make solids with the sugar leaves, etc as both will be coated by stuff best not smoked. I miss my solids. Pesticide bombs are good as well I believe...perhaps it`s that word bomb that is attracting me. Anyway, all the best mate and good luck.

Has anyone ever use regular led bulbs for growing? I'm starting a grow with some,but they are just seedlings now. Input would be appreciated.

[alltatup]

Hi Vonsulton, This article might help you. I just started using LEDs but know next to nothing about them.

How do u deal with the bugs in soil? they come out and seem to live in soil. I use happy frog soil.

[Retodd]

For outside in the ground I always use diatomaceous earth when planting. There’s a mix of hydrogen peroxide you can use indoor. I’ve never had too, but I’m sure you’ll find it if you google
