Here is an update, day 25 of flower. I saw the slightest bit of algae starting in the tube coming from the water pump and decided I would rather not fight the battle for the next 6 weeks and just turned the pumps off. The real reason I ran the pumps was so I didn't have to feed the clones by hand nor did I want to have to mix so much nute water to fill the 27 gallon reservoirs while I waited for the roots to break the water surface. So off they went. It worked great for what I initially intended it for. The plants are SUPER healthy right now, great root development. If I pinch a lobe of a leaf off and look at it under normal light, the green is dark and vibrant. The undersides look like satin. No browning, no burnt leaf tips. Faster nug development than previous grows.

I have been maintaining around 800 or so ppm. I find that if I put any more in there, the plants take more water than nutes and cause the ppm to raise. PH has been a stead 5.8 the whole trip so far, I have not been getting much of a PH swing at all. The most it has fluxed is from 5.8 to 6.0.

The second vid was just shot today, one week into the flower cycle. My system: - 400watt mh, going to be switched out to hps within the next week. - 2x 27gal storage containers from Lowes or Depot for around $12. Very heavy black plastic with YELLOW tops that I sprayed with a primer to make it so the light did not penetrate the yellow plastic. - I have two 60-gal air pumps Rating: 5
