I have also read that cooler temps help also,after they have poped of course,I start mine in my basement under a mix of cool white and daylight bulbs.I still get males once in a while but shit happens,I also believe that there are male seeds and female seeds,giveing them the right light spectrum and temp just makes for a better plant,this is just my opinion from past grows good luck peace and grow on
i keep growing males... what is wrong with my set-up?
- Thread starter Rhyspect
- Start date
9 males?? so how close does the light need to be? or are you talking about lux levels? my light is a couple of inches form the foliage,
ill try out the cooler temperature thing too!!

ok so im hearing that the enviroment can determine the sex of a plant I honestly dont see how that works is there any proper info about this

yeh I did see that oneton but light spectrum, lights not close enough, and temps. do these really make a change or determine the sex of a plant?
I dont know much about this but I thought the seed already has its genetic makeup whether its goin to be a male female or hermie etc if thats true then how does the above "change" the sex of a plant.
interesting thread

Increasing the level of nitrogen causes more females.
Increasing potassium produces more males while lowering the potassium encourages more females.
Lower temperatures and higher humidity increases the number of females.
More light from the blue spectrum increases females, whereas more red light produces more males.
14 hours of daylight will encourage more females...
This is all for the first two weeks of growth and it's all according to Jorge Cervantes growing bible. I think we can trust Riddleme more than Cervantes, so read Riddle's posts before jumping.

thanks for that info ppl I never knew that before and will have a little look into it, so the 1st 2weeks which is seedling growth (to me) makes the difference to the sex of the plant I'm day 13 so I guess Ill have to see what happens. very glad now that I got one of those hps bulbs with more blue spectrum. but I do acctually want some males.
once I droped the light time one hour a night till 12/12 and outa about forty seeds had something like 2 males or something dont know if the light thing I did made it like that tho

Yes genetic coding plays the major role but influences due to growing conditions can cause plants to go to what might be called or seen by some as being something of a secondary genetic coding, a backup genetic coding or even a genetically coded survival mode. People need to remember that cannabis plants only have one reason to exist, to perpetuate their strain's existence, to make seeds, or at least to attempt their best to make seeds. Because of that due to conditional stimuli a female plant at times will turn hermaphrodite. What is seen as a hermi trait and a flaw by many is basically a normal 'reaction' of sorts, a last ditch attempt response in the 'mind' or better said genetic engineering of a plant. Sort of a Plan A is failing so let's go to Plan B thing. If conditions are perfect or close enough to being perfect that sort of plant 'reaction' is far less likely to occur but if conditions are not up to snuff those sort of 'reactions' will be seen.
In nature groups of plants on the windward side of the group will have a higher percentage of hermaphrodites than in the middle of the group and a large percentage yet than the leeward side of the group will have. That means that winds that are consistent enough and of high enough speeds, not as in hurricane force winds or anything, is enough to cause plants in the wild to turn. If that happens in the wild it can happen indoors too IF the conditions are right and it points out how conditions can and will alter what we would see as being a plant's primary directive but is actually the plant's true primary directive .. to succeed to make seeds at any cost and regardless of what it takes to do so.
Plants will 'react' in certain ways due to conditional influences they experience during growth. Those 'reactions' can be ones we see as being positive and good or negative and bad but to a plant they are all good. Some strains will 'react' to conditional influences more frequently than others and some will 'react' to a greater degree than others. That is just how it goes and it is all genetically coded. If it wasn't genetically coded to happen it would not happen. It is just a plant's Plan B.

i would email your seedbank and get new fem seeds, i ordered 5 snowwhite seeds from narvina and only 1 grew but it turned hermie, i emailed them told them the whole story, how i germ'd them and planted them and they sent me 5 new fem. seeds and this time all of them sprouted! i still have 4 growing and i gave 1 away to my buddy, id give it a try the worst they can say is no
yes, but not always. In species who can change sex the genetic sex doesn't always equate to the genitalia. This is often controlled by hormones (this is how you create femanized seeds), so I suspect the chemical manipulations would be rather successful.
