Someone asked me to post some photos of the AIT (Air Injection Technology) planters I'm trying this time, So here they are. They are very similar to other types of hydro in that they use air pumps and lines to oxygenate the medium being grown in. Except that these are developed to be used in soil. I'm using them in a very porous medium made of coco, perlite, grow stones, pumice, worm castings, etc. The result is a medium that absorbs about 50% air and water each. Seems to be working pretty well. Really easy to flush, yet holds moisture and nutrients well. Unfortunately I didn't take any photos of the "air injectors" that are in the bottom of the buckets, but they look very similar to those used in traditional hydro, but rather than air stones the supply lines connect to a dome-like structure about 7" in diameter which doesn't get closed by soil or other fine particulates. But you use the same pumps and lines that are used in other hydro setups. I'm trying these because my grow space isn't easy to use 5-10 gallon tubs and this way each planter (bucket) is its own system_ keeps most issues contained in one planter. Also not obvious from the photos there is a 1/4" hole about a 1/2" from the bottom pot the buckets, it has a plug which can be removed to drain the water. I've found that what works best for me is to pull the plug, let the planter drain into the dish (about 10-20% drainage), then water again and as soon as water starts to run out the bottom, put the plug back in. You can hear the air bubbles "popping" out of the surface of the medium. The air being injected into each planter supplies plenty of oxygen so the roots don't drown. Every second watering I leave the plugs out and just let hem drain, then don't water again for 2 days. So here are some photos of the setup...A friend gave me the setup but there were only four buckets/planters so I went to Home depot and got two more 5 gallon buckets, drilled holes in the bottoms, bought a pump and some lines and two of the air injector systems and its working great. They sell buckets but won't ship them to my address so I just made my own_very easy and works just as well. You can also get plugs from the manufacturer as well. Cheers!
