hello im new to this kind of growing and any help would be greatly appreciated im gonna try the bubbleponics tutorial on this site. i got a 4x4x6.5 growing tent and a 600w HPS hooded light system.The hooded light system is vented out seperate than my filter system and i have the temps fairly dialed in at 75f to 85f its set up in a basement in its own room with an outside window so i have options. im gonna try the 600w bubbletronics tutorial on this site .. My question is am i gonna need a chiller in my 5 gallon resevoir totes to keep the water temp down?? it never said anything about chillers in that tutorial and im concerned my resevoir temps are gonna get to high
