Its all about the light penetration. Small plants, small area, T5's are great! Now if you have a grow room, big tall plants, you do need HIDs to penetrate all the foliage & cover more area, but in a grow tent with all that reflective mylar, you'll be fine. Just remember to have them close to the plant tops, but not touching. If you ever feel you need more light, just add CFLs.
catbuds Reviewed by catbuds on . Are 8 4FT High Output T5s enough? Hi all, are 8 4FT High Output T5s enough to grow about six plants in my Agromax grow tent? I was thinking about buying 8 4FT T5s, either 4 of them with bloom lights and 4 with growing lights or should I just get 8 growing bulbs. I was thinking of hanging both up top or a set of 4 on top and a set of 4 on the bottom of my tent would this work for flowering and blooming? Any help and info would be get. O my grow tent is 55'' x 55'' x 79'' so like 4ft x 4ft x 6ft One Rating: 5
