T5 Fluorescents

[rygo796]

Yeah i know they do put out some heat...but 2 4' 8bulbs WOW! I wouldnt imagine something like that being 'cool' necessarily.

I have light experience with CFLs but I figure Ill do like postman, 1" or so with the single 4bulb fixture with a fan cooling between the 2...and of course adjust height as needed for heat.

rygo796 Reviewed by rygo796 on 08-23-2006. T5 Fluorescents Anybody ever try growing under T5 fluorescent lighting? I Figure I could fit a 4 bar 4foot setup in my clsoet which would work well for heat issues, and they say they put out 5000 lumens per bulb, which I could scrog under and being so close to the plant it would be like using somewhere between 250 and 400watt HPS. Any thoughts? Rating: 5

I have the 2ft Version 4 bulbs 2000 lummes each in the top of my cab. So far for growing it works really well. I believe the reflector has alot to do with it as well. I remember reading about it on the net. SunSystem T5 2fter German technology reflector.

I plan to add some cheep side lighting to the cabinet in top compartment and flower with this light. I will post the results.

Regardless tubes are simple for me no heat in a small space.

Sun Systems T5 HO, 4 bulb setup. Seen 3 of them do some pretty good stuff. Takes a longer and yeah, needs to be really really close, but they are seriously cool. A 400 watt HPS produces SIGNIFICENTLY more heat. But it also produces more growth too. I dont think anyone will argue that T5 will out perform an HPS. However for vegging and clones they can be great!

hey dude, if you search for my other posts, you will see picsof my setup. I use a 6 tube 2' fixture in harmony wioth 2 4' cool whites and 2 4' wartm white florescents. Works greats. My plants have really really dense growth. These t5ho's are great but expensive.

I wasnt so much of thinking about doing 400HPS stuff with the fluoro's but I was thinking it was possible to have similar output to a 250HPS, which I was considering, but I like the lower heat output of T5
