Is an 8 Lamp T5HO Okay For My Flowering Setup?

I'm doing a closet grow in a 6x4 space and plan to flower 4 small autoflowering strains that I'm currently vegging. Would 8 2' T5HO Lamps be too little or too much for flowering? If it's too much should I just go for the 4 Lamp??

Any recommendations or tips would be appreciated, thanks.

for 4 plants, i would recommend the 4 foot bulbs.... I use a 8 4' bulb fixture myself.

I agree 4' = better lumens and coverage. The get brighter at higher temps also, I think max is achieved at about 95 degrees. A couple 2 bulbs fixtures for sidelighting will help too. Bulbs from 1000bulbs.com are cheap like 1/10 the price.

Or as many as you can afford. They are less than a foot wide so you can really cram them in.

Why not get a 600 watt HPS for $200 and be done with it? No vertical height?

i used a sun blaze 2' 8 lamp t5 fixture in my grow for fowering. you can check it out from the link in my sig. i just switched over to a 400 hps for the last couple of weeks though. They've only been under the hps for 2 days now, so you can get an idea of what 4 plants under that fixture will give you. In my opinion, it isnt all that impressive. It WILL work, though.

From now on, I will be vegging with the t5s and flowering with the hps. I didn't want to give in to the HID world for various reasons, but if you're gonna grow, might as well make it worth your while.
