Flowering

Just put 9 clones in clay stones into flower there were veged for 4 week but they never done to well due to the heat,they have been copeing with 100-d at max so the growth has been a bit stumped there only 8inch an for 4 week hydro they should be twice that.do u think 8inch is ok to flower at in hydro growing,i have a 10 pot dripper system,but hydro growing is all new to me i have been in a soil bed till now

you can but you wont have the yeild you want most people wait till they are a foot tall with at least 8 nodes
