Terra Acquatica & DWC

It’s what I use and I grow DWC. Very stable and quality nutrients. Not too expensive. If you’re going to go hydroponic I’d add Hydroguard to help eliminate root rot.

Looks ok. DWC things to consider. Water Temps are VERY important, roots will die at higher temps. Sterile system, as organic matter will likely sprout grow stuff that will cause root rot.

Expensive. I'd suggest Jack's 3-part setup. Two of which you can buy generic products at an even cheaper price. Less than 4 cents per gallon mixed if you buy in bulk. Dry fertiizer also lasts decades on the shelf, so using it over the course of a few years is fine. It's also ph-buffered and balanced so you don't have to worry about balancing it. With soilless/hydro context, there's even less concern about quality of ingredients. The pool of ingredients for 100% soluble and 100% plant-ready nutrients is small by comparison. There really is no quality difference from any reputable company. The ingredients are commodities, so don't overpay for them. Higher cost soilless/hydro products are just taking advantage of people.
