Running an oxygen pot system, with only two pots and a 25 gallon res. the res will be filled with 10 gallons, and am using either Aquaflakes, floraduo, or the flora series... Or maybe dynagrow. The reservoir will be outside the temp help at an ambient temp of ~70 degrees. I plan to flood 3 times a day for 15 min in veg and 4 times in bloom. Do you guys think I will need. Water chiller? Any recommendations? I just want the easiest, most hassle free grow. all the help is appreciated!
