Hi @Mageuzi
1) I do it anywhere between 21 and 28 days! Takes 4 - 6 weeks for seeds to mature so add that to the equation.
2) I started spraying my other plants down with water before I start pollinating the target plant(s).
Greetings from Russia! Your plants look great! Keep developing in the same spirit! If you are interested in following the adventures of weed in Russia, subscribe to my diary
Always love to see people collecting pollen and making seeds. Respect. Ladies look good as well. Spectacular work growmie. Keep doing what it is you've been doing and may the ganja garden gods give you nothing but good fortunes until the end
