The heat on the plants is ok but it's your water you want cool. Water chillers are way too much for me. So I used the A/C to keep the room and rez water at 70 degrees. It's all about your water in hydro. Plant could take much more than 85. It must be over 100 when you got the 1000 watt hortilux bulb on. good ventilation for freshair and A/C keeps it under control. Cold falls to the bottom and kept my water cool. 66 to about 71 most of the time. You can tell when the roots start to rot. Not a good smell, you know it's about over then.

Al explains the buds and most climates well. If you really turn the cold on at the end most strains will start to turn purple in the cold of winter. Only thing is they are way past thier prime.

Hope we help with info and keep us posted. Zandor will bust our chops if I tell you something stupid. LOL
