Flowering???

My plants will be ready to flower in a few weeks...approximately how long should i bud them for?

It highly depends on strain and what kind of buzz your going for.

Until they're done.

NOt really enough information. Could be anywhere from 6-15 weeks in flowering. Indica = less time. Sativa = more time.

What strain?

im not sure of the exact strain...they are clones from the lab. this is my first time so im just experimenting.

let them go until the trichomes are white if you want a head buzz & amber if you want a nice body type buzz.

Thats pretty general advice, but its acceptable in this case where we dont know what strain your growing. Watch the trichomes & they will tell you when to harvest. You can also sample some when you think its ready, IF your happy then harvest... If not let her go a little longer & sample again.
