The size of my vegging grow tent is 2.5 x 5 x 6.5. I want to use this tent to keep 3 mother plants long-term, and 12-15 clones to a height of 8-10 inches. Would a 4' T5 Badboy fixture of 8 bulbs be good for this? Or should I use a 250 or 400 watt MH bulb instead?
If it's a 4' 8-bulb T5 then you're using 8x54w, 432 watts. Yes it will work, but why not just use the 400w MH?
I hear a 400w MH puts out more lumens than the equivalent wattage in flouro. Don't know the specifics though. Definitely right about the heat, I went with T5's because I couldn't afford cooling
metal halide puts 30,000 to 35,000 lumens a 4foot x 8foot t5 puts out 40,000 lumens sorry a 400 watt metal halide
