I bought a Toshiba 36,000 Btu unit through a friend of mine that does hvac for a living and have not been able to get him out hee after i installed it to pressure test vacuum it down and release the refrigerant. So i would advise to get one you don't need a hvac guy out to get it started...

Got a few of these going to try them out

Has anyone tried the cool tubes that run through a hood?

Guess it worked old light mover pic 20ft wide holds 5 hoods.

don't know if this will show up..

Looks like i will be changing hoods and going with the max tube expanded 24". Which is 31.5" long cool tube and has a hood. I will be converting them over to hold 2 bulbs. The width and better air flow is why i will make the change.

I was thinking about cooling the exhaust air from the hoods with a water chilled heat exchanger to help with heat signature.

Using CO2 generator which will also produce heat when the burners are on.

I have a 36,000 Btu mini split to cool the room would it cool enough for no air cooling on the lights? I do appreciate the help thanx. Intake temps are 70°F at most.

Any advice on where to fey help on this issue?

I'm looking for a solution that is not exchanging the air in the room . I want to draw air in from an external source in through ducting through sealed hoods out of hoods back into ducting through a wall and out a fan that is sucking air through all of this. Most people are talking...

The other fan option is a 2905cfm 14 in fan and ducting.

How many cfm's do i need to cool 600w hps? I plan on running 12 inch inlet ducting then split it to the hoods on the light bar using 6 inch ducting. Then the same on the exhaust multiple six inch ducts to the 12 in to a 2050 cfm fan pulling air. The inlet will have a air filter all air will...

No hits on this just lots of lookers. I will wait to post pics until the mold is complete so I can show the finished product. And then get some feed back on what you guys think. And maybe a redesign if I get better ideas from the group. The mold should be done this week so hopefully a couple of...

I was in the process of building a media free plant support for the aeroflo units you would be able to use them in custom units as well. I was wondering if there would be a market to sell them? If I get enough feed back for them I may produce them. I would need to know what people...

put a pump on the drain outlet to pull the water out. They have pumps at home depot in the sump pump section that you can use a hose to go from the drain to the pump then a hose from the pump to where ever you want the old water going. You should be draining, rinsing,draining,cleaning the...

people mix brands all the time.You could call the GH tech line to see what they say or shoot them an email.They are always helpful. Good luck!

I started using bleach after being advised by fatman. It eliminated the root rot problem I now use it as a preventitive and am able to run higher res. temps. with no problems. He knows his stuff.

I set mine up run the pump 24/7 until the roots start hanging out of the baskets. Then I lower the level control tubes as low as they will go to the runner, and run the pump on a timer on a timer 30sec on 6min off. I use a water chiller to keep the res temp low. I shoot for 68 deg F.I change my...
