my grow last grow i had 13 f 5 m...
this grow i went with feminized seeds, a bit pricer but worth it i think.. u dont have to waste space with the males and u save of soil nutes labour etc...
they say there are ways the try and get a better female ratio..
1. giving seedling tap rooth 5 inches to grow down
2. a slightly higher N in early life
3. lower temps in veg 19-22oc
4. 18/6 light period
these are russian studies uhhhhhhh
