My little seedlings are only about 4 days old, when should I put a small fan in the room to get some air blowing on them?
as KH mentioned be careful smaller containers of soil can dry out faster but i use small fan from before sprout. when plants get larger the fans do also and they run all way to chop. you dont want hurricane force wind you just want the seedling to gently jossel some.Be extremely careful with that. New seedlings can dry up amazingly fast. Simply having a fan moving air around the room is sufficient to prevent stale air accumulating at the site.

i start seed in a 50 site rapid rooter starter tray i fill the small squares with soil. i dont use a dome my average RH is less then 20% outdoors when i water them i use a spray bottle on mist and mist the soil untill drainage is achieved. i mist with spray bottle at lights on and lights out.
Does super-cropping really effect sex?
Dutch Passion Website said:From literature and our own findings it appears that the growth of a male or female plant from seed, except for the predisposition in the gender chromosomes, also depends on various environmental factors. The environmental factors that influence gender are:
* a higher nitrogen concentration will give more females.
* a higher potassium concentration will give more males.
* a higher humidity will give more females.
* a lower temperature will give more females.
* more blue light will give more females.
* Fewer hours of light will give more females.
I dont have any knowledge in this area, but the wind statement just seems outlandish, and flawed. Wouldn't the wind have the same effect in sense of sexing for females(meaning it has no effect at all)? If a female was grown in a windy environment, wouldn't it be more succeptable to pollination as opposed to females without the breeze? Maybe air circulation is just stimulating period? Just thoughts.You grow a skinny plant that is constantly under a stiff breeze and its gonna realize that. Its gonna realize the best way for it to fuck lots of other plants is to go male. If it goes male its lonely top cola waaaaaay up at the top of this skinny 4-5 foot tall plant it is in the perfect situation to spread pollen. It thinks its living in a valley or near the sea with a constant wind going on. It thinks that shit is gonna carry its pollen for MILES. Of course it goes male!
yea dont listen to me listen to the more advanced growers i guess the 10 seed 5 each of 2 strains i grow along side my clones dont count. and ifn i didnt grow from seed guess i wouldnt have made 28 polybrid crosses of med strainsThat's some fine advice for someone growing from clones. Clones are genetic copies of their mothers and will end up just like them unless you seriously fuck something up.
However, I don't think you should be giving your advice to someone who is growing from seed.
Seed-started plants are very impressionable, the kind of environment they develop in can have a massive impact on whether they go male or female. Having a fan constantly blowing on them from a young age is an environmental factor that will push them very hard towards being MALE.
Among all the environmental factors that can cause males; topping, high potassium to nitrogen ratio during veg, warm color temps, short nights, high temperatures, etc. the worst of them all is blowing them with a strong, constant breeze. Cannabis is a smart plant, it makes 'observations' about its environment and then changes it's chemistry to suit. Some of you Icmag gardeners seem to grow cannabis in the perfect conditions for making males.
Tall, thin, spindly plants vegged with very long days (or 24 hour light), possibly tipped or fimed under orange lamps with a fan constantly blowing on them. This is just begging a seed-started plant to go MALE!!
Cannabis is a plant, a plant that came from nature. Plants in nature behave according to their evolutionary imperative: reproduce themselves. A cannabis plant's goal is to swap genetic material with as many other cannabis plants as possible. Just like us, they want to fuck everyone!

The wonderful thing is though, it works in reverse. You can set up the environment to make a plant 'want' to be female instead. Supercrop, run blue lights in veg, long nights, cool days, no wind, low stress and other factors. Short, squant, bushy plants with many many growth tips are the result. These plants 'realize' that with zillions of growth tips close to the ground and no wind going on their best chance to have lots of sex is to form tons and tons of bud locations to get pollinated by a nearby male.
Its a classic nature vs. nurture scenario. Genetics certainly count, fem seeds go female much more often than normal seeds, but unless you are using clones then you need to mind your grow-space and make the environment suitible for female plants. If you ask me, nurture beats nature in this case. I've got 5 plants going from totally mixed, totally genetically different seeds. Every single one of them is going female. Give me any seed you want and I can do it over and over again with 100% predictibility. That is the power of environmental control, it should be getting more respect around here.
