Sorry if this seems stupid but idk how environmental factors can change something like sex.i guess when i think of sex of axplant i consider it predetermined by genetic material not its environment. I have heard before that seeds germ'd at higher temps have higher percentage of males. Obviously you get a herm every now and then but for the most part it is one or thecother with a lil heavier on the female side. So if someone could help me understand how environment determines sex or just link me to a solid research paper on the topic would def be rep worthy.
Side note, kinda more of a breeder question but since i just thought of it ill ask here too. Anyone ever seen a male turn herm to produce buds? Like i said more of a breeder question since not all of us have a vast experience with growing out male plants... food for thought i guess lol
keep it green guys

There are many papers on environent ,hormone an genetic sex determination in hemp.

(Most of them reference Mohan Rams work also.)
I'm always reading them, but some are hard to follow.

I read UV treatment of pollen also increased fem rates?
wish they would have given details...



Nevil wrote of reversing males to get flowers @ mr nice seed forums.
He would sample the male for desired traits, when selecting males.
He said he would "go get a bottle of reverse"?
not sure exactly how or what he used..

That is awesome. What a way to really know what the male is contributing.

There is a product form dutch master called reverse and it is supposed to stop hermies. Like the opposite of colloidal silver and STS. I believe STS/CS only works for making females go male.
 
Guys got some seedling off to a descent start. Got the tap roots poking out of the grow plug, are they ready for transfer to the hydro garden? If not how long should I wait? Also it that RH Ok to grow, seems low to me.

If you want to talk about genetic bottlenecking, SK1 is a classic case. The best line that I got from Sam, was pretty bloody good. I would say that that was his crowning achievement. I separated 2 lines from the best single parent mating, and kept them appart. One line had Red labels and the other Blue. I kept doing single parent matings using the above mentioned tek. The plan was to put them back together and then give them out. I'm sure that SB has used these wisely.

Seems this method was also from Mohan Ram

Bromeflor

As for methods....
Any one in academia have acess to the Dr Ram paper I cited???????
They want 39.99 to read it for his dosage/ recipe?
I can't find it anywhere!?!?!?!?
Dam


Guess Id follow dosage for ripening fruits an veggies with the chems above on a guinnie pig male or clone....

for me, i think the craziest thing about that article is the fact that it was published in 1970...

Aaaaaaaaggggggghhhhhhhhhhhh!!!!!!!!!!!!
 
Some pics of my first and brand new garden.

Seedling are just over a week old. Loving that IG 420 with pontoons! (Thank you Darryl and IG). What do you guys/Gals think of my low RH. Is this a problem for growing later on?


P1010716.jpgP1010717.jpgP1010718.jpgP1010719.jpgP1010720.jpg
 
Please can some of you experts comment on the low RH? It is always in the 20's. Freaking out kinda because I am near Tacoma and the outside RH is usually 80+. I was worried about high RH but in reality my house is dry as shit! Do I need to increase the RH???? Please advise
 
PS Just want to comment on the Indigro 420 lights. These things are the real deal man, I can just tell my ladies are gonna love this light. It is kicking out more heat than my Lumigrow 325 was but nothing near what a 600w would be putting out. I feel I made a great investment on the IG.

Will keep posting and keeping you folks updated on my first grow.
 
^ Glad you got into this thread, Mr John, 730nm is covered in depth here and I do believe there are links to good reads floating within these pages. :peace:

^ I would...20% is low......I would think you want it up around 40% or so, everyone is slight different. Mites love reduced humidity and your plants will probably drink too fast or it will it evap to quickly for some roots to get at.....

Im in the 503 and keep mine around 50-55% and humidity is probably high as shit right now[[in terms of outdoor ambient RH], but it is 7 F right now, so it is "warm" here!
