My room is already all setup since a while. Actually, I have 4 of these tables with 3 x 1000W on each.
For intake ventilation I take fresh air from outside using an 8 inch CanFan that is pluged on a thermostat. For exhaust I use 2 other CanFan (8 inch & 6 inch) that are connected with 2 seperate carbon filter.
To get the room even more fresh, I use a big commercial water cooling A/C that is also connected to a thermostat. Finally, I use plenty of little(5) and medium(4) size fans to distribute all that air in the room.
I am running with this seteup for over a year now and even if I am well equiped with the ventilation, I am still not getting the results I shoud have... The plants in the middle of the tables are not growing to their best (smaller than the other on the sides) and are getting yellow with the time (not burning).
Is it just a matter of cooling? should I get the cooled air from the A/C directly to that spot where it is hotter? ... note that actually, I just throw that air in the room... not directly headed where my lamps are. Or maybe it is something else I just didn't think about. Maybe the roots are getting to many heat??
I am missing a lot of production with that problem and it is getting kind of frustrating....!
Hope these infos will help you to help me! hehe
I'll try to get you some pics this evening...
Thank you very much guys
