So I'm down to the last of my funds for my grow room. I have a decision to make, buying a RO system or a water chiller. My grow room temperatures are 77-78 during light hours and my res temps are a few degrees below that. I don't want to take the chance of mold or root rot of happening but at the same token RO water is ideal.
So what should I buy? I am almost out of capital to spend. |
