Omisananswered grow question a year ago Hello growmie :)
If put a net be really careful with branches and don't force them...
Personally i think defoliate is better, cut off the leaves that grow in the middle of the plants (for passing the light, sure) and all the leaves that don't receive enough light in the bottom of them..but be careful and cut them off a bit for time (5 leaves for plant every 3 days?go slowly, u can defoliate until the end of grow)..maybe use your finger to cut it out and go as sweet as u can when do it, just for reduce stress..
Sorry for my english, i hope i helped you :)
Good, green, luck!
