12 to 16 with a 1000 watt hps over it do you some justice lol get about an 1-2 oz a plant depinding on strain jus vegg till the leaf tips touch and flip to flower worked great form me i did 32 in a 4x8 with 2, 1000 watt hps over it and i did jus fine
Like 9 plants veg till leave tips touch flip to flower depinding on strain and the light you have them under get like an oz a plant or more and thats a very simple way to go
Well some type of streess has happed to make it stop growing wat do you think happed if not the light it will snap outa it and grow under the new lite sure but that definitely slowed it down
That mite be this issue your tryn to clone to much plant .... if they dont fit under the dome there too big in my opinion l.... jus try cutn all the big water leafs off and get a spray bottle and mist them mite help you out with them bigg cutts that way your plant not trying to keep alive...
