OK. I noticed some funk going on in one of my reservoirs. This was not good seeing as how i had yet to add anything other than Ph down. By the way, nobody told you this, but you will go through a lot of the Ph adjusting stuff very quickly. At any rate, I took this as an opportunity to find out just how much work I was really getting myself into here. Obviously, as judging by photo 1, foam in the res. is never good. However, when your grow opp does not have a water source in the immediate vicinity, i.e. the same room, this can cause challenges. Water weighs around 8 pounds per gallon, and I have about 16 gallons per res. which means these mofo's weigh about 128 pounds in total. No way in hell I'm picking that shit up as what's left of my back would most certainly protest very loudly. Good thing I have auxilliary reservoirs to make water transfer to the bathtub a breeze.
Since I had both reservoirs out, I took this as an opportunity to address what was most certainly a weak link in the chain. The fact that I had been using metal spoons attached to my air curtains via zip ties to weigh them down. Ingenious you say? Not so much. This was bound to affect my reservoirs in a negative way. The problem being my air curtains were about an inch too long, and as you know, those suction cups are worthless on anything other than glass. I used a knife to trim the air curtains to size and used Locktite to permanently affix said air curtains to the bottom of the reservoirs. Now I have a much more even distribution of oxygen throughout. See pic #2.
Since I was changing out my reservoirs, I decided now was an ideal time to introduce a nutrient solution to my plants since the main taproot on 3 out of 4 had managed to probe down into the water. Anything to help after all. I used a very weak solution, less than 200ppm. I am hoping this will help speed things up here. My next post will include pics of my plants, as I am soon to exceed the maximum allowable number of picture attachments per post.
