The res stays right around 70*F, and with the use of beneficial bacteria and the venturi she has been thriving.
That's great! I just thought I would mention it,cause that is the norm for most operating res. tanks. Since you have it under control..:thumbsup: Adding the oxygen to the water at that temp. will make it harder to uptake the added oxygen,by the roots.. Lookin' good,My Brutha!
GaGrown Reviewed by GaGrown on . LSD RDWC SCROG GROW This is my second attempt at growing. The first time things went horribly wrong. (there is a link in my signature if you are interested in learning from my mistakes) For this go-round I will be running a 5 site Recirculating Deep Water Culture system. In a 3'x3'x7' cabinet, with a 400 watt MH (veg) and a 400 watt HPS (flower). I also purchased some Barneys Farm LSD from the Attitude seed bank. I highly recommend Attitude so far.
