how many plants are you looking to grow, and what type of bubble units are they? describe, any pics?Hello,
I have a 56" x 56" x 78" (4.67' x 4.67' x 6.5' ) grow tent. I am going to have 12 hydroponic bubbler units with between 24-30 plants total. I currently have two seperate carbon filters venting out of the tent (1 smaller 7lb and 1 15lb with a second 6" duct fan, not incline!).
I want to properly cover the entire grow room with light. I currently have a glass HID fent fixture that I can connect to my vent ducting.
I want to know what the difference would be between (1) 600w HPS and (2) 400W HPS? Would it be worth the hassle? Would two fixtures end up creating too much extra heat to be worth the added benefit? Will (1) 600W HPS properly cover my area?
Any thoughts or advise?
Thank you!
(2) 400W vs (1) 600W HID?

At least 24 plants for sure - probably a few more than that depending on how things go. I'm using self made bubbler hydro units; they were great. Each measures roughly 1.16'x1.67' and I'll be able to fit 12 of them into my 4.67'x4.67'x6.5' tent. There are 8 holes on each unit with a 3" net pot in each. I'm aiming for 2 per unit and maybe 3 per unit in the center and 4 corners, but we'll see. Last grow was in a closet with the same strain in the same units and 2 per unit really was the right combination. I was able to get about 3-4 oz/plant with the strain I'm using.
I've be able to control the temps without any problem so far with my 400W inside the tent with my mothers inside. I'm up for suggestions but I've heard that the 600W HPS tends to cover 3'x3' great, 4'x4' max. I've done some testing with my 400W inside the tent now and have noticed with the 3 bubbler units I'm using, that the closer I get the light to the plants, the more the light concentrates to the center and misses the outside plants. This is my concern with not using an Umbrella 4'x4' reflector. I understand that the cooltubes allow you to get the lights closer to the plants, but keep in mind this is not an option for me when trying to cover 4.67'x4.67'. As long as I can keep temps in check, I'd prefer to have the 4'x4' Umbrella reflector for a mere $50 more (when you purchase the 600W HPS from HTGSupply).
Any thoughts? I GREATLY appreciate everyones continued feedback; this is really helping me make decisions!
what strain did u get 3-4 oz off? im going to grow blue cheese indicta and i believe the yield off that is good! are u using 10 gal buckets? coz i was going to say you can fit alot more than 3 per tub if you lollipop ur plants. u cud really get alot going then!!!!At least 24 plants for sure - probably a few more than that depending on how things go.

also i would just like to add that my set up grow tent is 1.2 x 2.4m x 2.0 high and im going for 2 x 600w lamps, also im going to use 8 bubble tubs with maybe 6-8 holes cut into each one, all linked up to a main res outside the tent with a water pump in to mix all of the nutes in each tub and then back to the res, this will make testing my ph and ppm alot easier, also the res is moving around nicely, with of course 2 airstones in each tub, also i am going to fit the main res with a stopcock so i can fill the tubs automaticly as soon as the water levels drop!
i was going to put 2-3 plants in each but maybe im going to try get 4-5 a tub now instead and lollipop them, just a thought for u!

Why does it gotta be a cooltube or "umbrella"? Why can't you just get a big ass air-cooled reflector like normal people?
