I have a stealth hydro box an, swapped out 3 separate CFLs for 2 48 inch tubes at 6500k same as the smaller bulbs.

Question is, will this be sufficient enough?
This is how the setup is.

Should I lower the lamp?
I had an issue with 3 separate light sources, some plants got taller then the other while some were light deprived, so there all different sizes, however I am hoping this will help.

Any opinions?

how many inches are the light from the plant's ?

just remember that fluorescent do low heat our put :) so you can go closer then hps/mh and allot of other light's to and if you have a glass cover over the light's you can go even closer :)

You need to get those T5's within 6 inches of the plants. Even closer with airflow between the tops and the lights. I would use your CFL's as sidelights. Especially on the inner side with no reflective material.
So you have 10,000 lumen with a 4 foot T5HO 2 bulb and maybe pickup another 3K with the CFL's. Just a thought...and what's with the really wide leaves on the little one?
What is the strain?

I never thought of that, good idea OMB.
I will put up 2 lights on the job reflective side.

An I got the bulbs alot lower now with some chain adjustments.
The strains are White Rhino, an there is one that's random.
But the small one with big leaves are White Rhino.

32 watt.

So at 32 watts, that would mean your fluorescents are T8's & not T5's. (T8's are standard shop lights). As long as they stay short & 'stumpy', that's fine. CFL side lighting is almost a must though. You do know that you can switch those out for 40 watt tubes? They come in a two pack at walmarts really cheap (T5's are 54 watts). I'm currently vegging under a shop light myself, then they'll go under a 6 tube T5 system with CFL side & under lighting for flower. I grow 'stumpys too, SOG. I find it more cost efficient indoors. Growing the big girls, way too expensive. I save those for outdoors...... :) :) :)

BTW, 3-6" is good for the lights you have. Little bit more, maybe 4"-8" if you ever get T5's.... :) :) :)
