So I have been perfecting my system for the past month or so and it is just about ready. It is a small scale prototype for a larger system I am going to build later. It is going to have two tubes with only 3 plants. Two 25gl rezervoirs connected with three 1 inch bulkheads and 1 inch pvc. The system has a 400gph pump. I am going to have this all in a grow tent that I have because the room this is in is too big for just three plants and I can better control the climate and make more use of the light in the tent with this amount of plants. One of the rezervoirs is in the tent and the other is outside. I have an 1/4hp aquarium chiller w/ a 1000gph pump that will take water from the outside rez and feed it to the inside rez. The entire system is insulated with radiant barrier so that the root zone temperatures fluctuate as small as possible and so that the aquarium chiller doesn't have to do as much work. I have a Sentinnel EVC-2 climate controller that keeps everything perfect. I have the temps at a constant 75F and humidity at around 55%(it was around 65-75% during veg but today is the first day of flowering). I have 1000watts of light in a air cooled reflector used with a 425cfm fan. The air that cools the light never mixes with the tent air, it is sucked in from outside the tent and then spit right back out. I have a 800watt portable air conditioner that will keep the room with the tent in it at a constant 70F. To keep it cool in the tent I have a 440cfm can fan connected to a speed controller (set to around 250cfm) and then connected to the EVC-2. For now I just let the air vent out of the top of the ten but later on I am going to install an exhaust.

Man that is a beautiful set-up. That controller looks awesome. I'm subscribed.

I'm going to build an almost identical system for my next grow. Got a spare water chiller from my Reeftank too.

Nice man, the chiller is definitely an essential part. No root rot...ever, and also the water holds more DO (disolved oxygen) when the water is 68 or so compared to 75.

very sweet! How does exhausting through the filter work for you? Im thinking about doing that. But it looks like the other end of the ducting is just sucking in outside air?

The only thing that matters is what's going on in the grow room...

I actually have it set up the other way around. I originally was going to use that fan for two of these reflectors but I am just using one right now so I justput the fan on top of that little filter to cut it down a little, as well as cut back on some of the noise. The air then just comes out the top. I havn't been using it for smell but later on I might put it inside the tent to use as an exhaust/smell controll.

Btw Vaporbros, is that piece in your avatar yours? If it is, that bowlpiece is fucking sick....

yeah its mine. The bowl was done by Opus, he blows alot of the custom ROOR bowls and this one is supposed to be his first one for ROOR. I have more pics if youd like to check it out some more. Thanks!

That thing is so sweet, I was looking for a custom bowl for my ROOR, but nothing I have seen has been as sick as that. But yeah for sure just post the pics here if ya want.
