Growrilla single pot DWC or Oxy ring

The air pumps are never silent... a small air pump helps.... fine for 1 bucket, but if running many it becomes inefficient and a mess of cords. These are essentially the same exact thing. One has a ring at top that drips? So, less of a hassle early on when the roots don't reach down to the water. that might be enough reason to go with the oxi ring option. OTherwise these are simply DWC buckets like any other dwc bucket. Consider DIY'ing this as it might be cheaper. hydro fertilziers -- 100% plant available, 100% soluble... easy peasy. I'd suggest the 3-part setups -- Jacks 321 (j.r. peters), masterblend, cropsalts, megacrop, southern ag etc.. many have a similar 3-part setup -- some "base" then calcium nitrate and epsom salt (magnesium sulfate). The latter 2 do not need to be a brand name. Like generic Rx drugs, no-name brands will be molecule for molecule the same thing and cheaper. If you buy 25lb bags, you'll mix at 4 cents per gallon, which is 1/5th the cost of most fertilzers out there. Dry nutes can last decades, so taking a 5 years to use it is no problem. I spend about 5 dollars per pound produced on fertilizer. It should be one of the cheapest things you pay for on a per year basis. All these brands use a similar ratio and concentration when it's all mixed up... some variation, of course. Regardless, you'll need small adjustments for your garden's variables. I have a picture of the ppm breakdown of what i use in any of my 3 newer diaires - in the germination week. I give a bit less than instructed by Jacks 321 setup, YMMV. Great thing about this type of setup -- never have to worry about a calcium problem and you don't need extra products to fill out the full, well-balanced diet. The three parts allow enough leeway to adjust to any symptoms seen and avoid them in future. Regardless of what fertilizer you go with, keep track of it.. adjust in systematic and intelligent ways. People that struggle with fertilization long term and constantly run into issues every single grow are probably blaming the plant when they need to blame the formula being too esoteric to work on a wide range of plants. Fertilization shouldn't even be much of a concern by your 2nd or 3rd grow if systematic about it (a bit longer to learn soil, but not much). Once i switched from FF trio to jacks, it was easy as pie. 2nd grow looked amazing seed to harvest. FF trio was a shit show the entire time. (this was a soilless context, but it's the same formula for hydro)
