Surely you bought feminized seeds..Surely you did!!!

Surely did not lol

Well I can tell you this from everything I've read by well known and published authors on the subject of cannabis all agree the temps you start your seeds at, will play a part in determining their gender, I've even read in a cannabis breeder's bible that the gender is possibly even determined more later on, not just at the seed stage, but also in the stresses the plant may be subjected to which could cause it to hermie, perhaps this is why they question at the exact stage(s) gender could be set. Now when you say "Mother Plant" I used to just think of a 'mother plant' which someone would take clones from, but now after that book I see the term 'mother plant' as being a completely different type of a mother plant, as they will look for a female mother for breeding. Before I read that book I would have bought feminized seeds, but now I see the other side to not wanting to have the plant I get seeds from previously stressed to produce the feminized seeds.

In the end my own reading really did help me to understand in the end the "good genetics" I am looking for could be completely different from what you are looking for, if I need a plant to resist pest outside, and you have no pests inside then what we would deem a good genetics mother will be completely different. People who grow lots of plants will look for uniform size, branching, etc.. so each plant will fill in the way they want and expect it to as not to waste light and space. Whatever plant you clone is going to be an exact copy of its mother, thus as long as you are happy with your plant... clone away and call it a good mother, unless you want to start growing a number of plants from seed and start looking for the one's which meets the criteria you want for your growing environment.

Which was another interesting point I noted as to why some plant strains hermie... If a strain is grown to grow outside, but you grow it inside it could cause it to hermie, thus why they tell you so much about seeds when you order them as if they are good inside or outside seeds, how tall to expect them to grow, you can even look up to see if a certain strain is known to have problems if grown in certain ways... all in all I found reading up on the subject of mother plants, seeds, strains and how to choose a good mother plant rather interesting when I did it myself, I hope it helped to peak your curiosity enough to go do some of your own research and reading on this subject as well.

In light of your above comments since my post, I will tell you this that the book did bring out... in order to even find a mother, they recommended putting all the plants into the Bloom room and stressing them with an unusual lighting period, which you keep doing and then watch to see which one's hermie and finding which one's didn't, always pulling the hermie's just as soon as you spot them. They made some comment to the effect of out of 1,000 plants, maybe only 100 of them will be F/F in other words they will not hermie from the lighting be erratic, of those 100 plants they would then look for the baseline of they deemed to be the "average heights" of them, pulling all the others which was taller or smaller, of those remaining they would sort it down to the things they then wanted to look for in their plants. As they brought out if you are an indoor grower you worry more of humidity than pests issues, thus a plant could be great against pests but if it has an issue with getting mold problems easily then you'd just toss it out never knowing it because those genetics aren't what you are looking and testing for in the hunt for the perfect mother for you. They did make mention how the process of looking for a male donor is a bit different and how it is so important to realize the male donor can be different on each flower site and thus each of the buds produced there as well as the seeds would then actually be from a different crossbreeding even of the same strain, thus make sure you keep track of what male donor pollinated that bud site if you hope to recreate that exact strain cross. The book is to help people grow and even stabilize their own strains, including back crossing the genetics to make it a lot harder for anyone to steal your creation of a strain if you choose to bring it to market or just share it with friends. All in all I learned a lot of things I never knew, and it was a very interesting read.

Ed Rosenthal...all the way!!

**PigSquishy** · 03-18-2017, 10:53 PM

The Cannabis Breeder's Bible: The Definitive Guide To Marijuana by Greg Green, and I agree 100% with Green on Ed Rosenthal as the best basis to understanding EVERYTHING, he really does have a Ph.D and is one of the biggest figure heads out there to pave the legalization of cannabis, he's had a column in High Times Magazine "Ask Ed", he has written books on cannabis growing for years and even other scientific papers not on cannabis which have gained world renowned attention and recognition. I will tell you this about the book by Greg Green, it is very well written like Ed's work, but with one major exception you are following him one minute and you turn the page and go WHAT???? and then you are lost for a whole very important section you will spend a lot of time trying digest and figure some of it out, or at least I had that issue in reading it. It took me a lot more reading to be able to come back and actually understand what I wasn't getting when I read it the first time, with Ed you can be completely new to growing without a single clue and he will hold your hand and walk you through everything you need to know to be a professional grower and never run into the first issue he didn't explain along the way.

I should note the book by Greg Green is the 2nd part of some other book he wrote according to the beginning of the book, I DO NOT HAVE HIS OTHER BOOK, perhaps that would have made a difference in me getting more out of this book, but I just barely got any information on how things work and then I got dumped straight into charts showing how it all works... and I was LOST without a clue as it felt like going from high school to the middle of college classes with only a couple of paragraphs to prepare you for it.

To try to put him into a real life perspective I did a little digging to try to show you what people think of him.

Thank you both for the input! I have a barnes and noble giftcard somewhere will defintely pick up eds book. What do you guys think from this picture.. Should I switch them to flower? I have 20 inches left that I can raise my lights. They are 8 weeks old today from the time the seeds popped and i put them in soil. There about 10 to 12inches tall from the soil but I have done considerable training. Also what do you guys think about revegging these plants as my outdoors while I sort through my seedpacks inside during the summer to find my 3 mothers? Ive always been timid to reveg idk just doesnt feel right to me for some reason

**Green75** · 03-19-2017, 10:45 AM

Why reveg...just take clones then flip to 12/12...keep the clones from the original plants that you like...use them as mommas....
maybe I'm confused...

**GDTRFB95** · 03-19-2017, 03:24 PM

One of my sweettooths has been battling hard against this issue I have tried hard to fix it. Flushed 2x with phd water and got alittle better each time. She is growing better but still putting these leaves off. New growth is banned like this and all past growth has lighter yet remaining bans on the leaves like this. The new growth looks really light colored but I i believe the leds are exemplifying it a bit. My two thoughts are magnesium and possibly slight iron deficiencies since its not just developing from the base of the plant? Im growing soiless and water a bunch with no nutes but have been trying to keep giving calmag no matter what since this happened(very early on) and has improved drastically but not fully. Been trying to fix her up before the switch to no avail. Could it be something completely different than what im treating? The diagnosis page has been the hardest part of this as it appears the same issue can show slightly differnet across strains

**GDTRFB95** · 03-19-2017, 04:38 PM

Thank you so much for helping me. Unfortunately (like an ass) I stopped taking notes in my journal because I kept getting done in there so late every night and I cant find the paper i did write ph stats on. My well water is 7 on the dot and with nutes it goes down a bit from what i remember. I had bought pH Adjusters but haven't used them yet because I remember the numbers coming out right when I did do the math.(for soiless) I am going to give them one last veg feeding tonight and switch the light schedule too unless I should try to get this girl back into perfect health first? I will record this time and post the phs here in a few hrs.

**Green75** · 03-19-2017, 04:49 PM

Soilless...ph at 6...always and forever

**Green75** · 03-19-2017, 05:07 PM

Nuff said on that....

**PigSquishy** · 03-19-2017, 06:05 PM

To comment on the Re-Vegging of some plants, I honestly am not sure what to say about it... Yes it can be done, it is a huge pain to clip off the majority of the buds while leaving the plant completely intact, hence how you save so much time in re-vegging because you keep the plant's structure and roots, the few ends you do cut off well they will just bush out more for it so no loss there. Because of all the cutting off the buds, having to then flush the plant and put it back to veg mode can be quite stressful, especially if you weren't keeping your scissors clean to prevent infections and other issues to help try to kill off your plant. But if you think the plant is doing okay, it may not be and I've seen them die off at the roots before the leaves and such, which in turn can attract pests and diseases, molds, and overall problems if you aren't paying close attention. Say you do get through the remaining bud you had to leave behind will dry up and you can collect it later, the books say you have to leave some behind, and so it always has been this way. When the plant produces again it does seem like it was a greater yield from it, and since the plant structure was already there, it did allow for a much faster turnaround on yields... but it was much more of a pain to do, then there was extra risks involved and the quality was exactly the same, which begs the question "Was it really worth it?". Of three plants I tried this on, one died right away after killed from the roots by something, I assumed stress weakened the root structure and it got a water borne sickness. The next one died when it was put into Bloom again, it never really recovered from the revegging and just stayed pretty much the same and when put back into Bloom 2-days later it just dried up completely dead. The third one went all the way to the end, but really died off at the end of harvest, so clearly there is a lot more to revegging a plant than what people think there is and perhaps that is why more people don't try to do it.
