flowxmananswered grow question 6 years ago Hey, I grow on the window too, and in the summer I'm out for the day in the sun, they grow well, only the yield is a little lower. At home it is better that the plant does not attack as many pests as outdoors. Outside it also threatens pollination from some distant plants. Put them on the sill in one row only. They will always bend behind the light, it doesn't matter. Leaves do not remove leaves until they are more blooming, and then only the lower ones, withered or large, which shield the buds and cover the flowers. Also, because of the more light it is good to put under the pots and behind them, a film reflecting light. I use a thermal insulation foil used by rescuers. :-D Stick it to the box and you have a handmade growbox: -DD
