    Ok, I have a tent I've used for both veg/flower. I want to build a veg only area. How many cfl's do I need to germ & veg 10 plants for 3-4 weeks? After that, I'll move them into my flower tent. Thanks :)

    im running ten 23 watt cfl and a 2' t5 in a 2x1.5x2.5 grow box. total lumens is around 18500. is this enough to produce fat dense nugs? there on the 2nd week of flowering

    You'll get fat enough and dense enough buds:) its tough with cfl's,too many variables.What are your temps? Depends on strain.How many plants you got?You say 2 weeks flower,is that from 12/12 switch or have you seen pistils?Have you accounted for stretch?

    after adding my exhaust fan today temps stay around 78 and 80. i got 4 plants in there right now, all at the same level. its been 1 week since i first seen pistils. strech has happened plus i got ton of space to raise the lights. also i suppercropped some of the strechy ones.

    Sounds good,looks good:).I think you are off to a good start and that you know what your doing.You'll have a little more stretch to deal with but no big deal.Make sure you don't have any light leaks,keep your temps down and watch your watering habits.GL.

    Look to run 7 to 8 100w (26watt) 6500k cfls for veg and add 4 to 5 60watt (14 watt) 2700k for flowering, that's how i do it. Finishing one up right now, on its 4th week of flowering
