Yeah I know what you mean about the bloom phase... I had to top those bitches off before when my last batch went into bloom. I usually had to top off about a gallon a day per farm. I usually will add 1 gallon to each one and also add one full dropper of ph down to each gallon added. I got the right touch for the ph levels here in my area. Seems that 1 dropperfull of ph down works for each gallon. I may look into getting a controller but for now I will have to do it the not-so-easy way. I usually have no issue doing it this way so far. thanks for the input and more pics to come as it goes. So Herbie, maybe you can direct me on how to set up a recirculator using a 5 gallon bucket? Thanks!
