when I say parabolic reflectors I mean for the two 600W HPS I would runn in the flowering room ..
look at our friend reggaerican plants and light/set up .. I would do it similar
with that kind of space I would make a sea of green and get them parabolic reflectors .. with two 600W HPS you can cover a lot of ground with good penetrations .. then just a nice 8" ventilation/filter ..
atlest thats how I would do it ..
about Veg and T5HO .. I use em .. and have made a lot of research and made some test with my light/foot candles meter
need to keep em 2-4 inch`s away from the plants ..
T5HO provide great par light for weed and nice lumens output .. only real down side is penetrations ..
keep the plants/grow with in 10 inch`s .. after 12 inch`s I dont even get a reading with my light meter ..
with my 600W HPS I have 7x the light output at 10 inch`s as with T5HO 2 inch`s away !!!
at 20 inch`s I can still read 3x the light output as with the T5HOs 2 inch`s away ..
