T5 tubes are great and u get nice results, but u wont get near a 400w HPS unless u use shit loads of them tubes...i use an HPS for flower and she puts out 52 000 lummens so it means u would need 10 of those T5´s.Anyway for small spaces tubes are allways a smart choice and they´re cheap and take less juice the HID´s so all things considered they´re a good choice.
OmegaVermelho Reviewed by OmegaVermelho on . 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
