Saturday I received 2 @ 45w ufos (NW + WW). The WW replaced the 4 hanging globes in my LED tent, the NW is being used as side lighting in my HOT5 tent
Out of 7 seeds, it turns out 4 are male, including a 3ft G13x WW that I will pollinate to a few branches of a WH x WW female of similar size. This should be an awesome cross
I will move the female, currently under the leds, to the hot5 tent, and use the led tent for WH X WW clones
4/7 males is very high IMO. I was reading through one of my grow books Indoor Marijuana Horticulture by J. Cervantes, 2001 and came across a page regarding 'feminized' seeds, but instead of buying them, this page (#261) provides tips to make your own, or at least to increase your odds of females
* Fewer hours of daylight
* More blue light, less red
* High Nitrogen
* Low Potassium
* Low Temps, but high humidity
Obviously, these are not cast in stone, as Sats will want more light than Indicas, so maybe 16 hours for veg instead of 18, and for Indicas maybe 15 for veg
As for blue v red lighting, more blue up until plants sex. But what does 'more' mean? We know that mj only needs ~ 20% blue (<460), so maybe you double it to 40% until you know what their sex is, then drop it back < 20%
