Mark, I’m not sure if you’re still tracking this thread. I’m trying to emulate some of your approach with 4-18-38 in grow bags with ProMix. One key difference is I have 10 gallon grow bags.

My concern is on fertilizer concentration build up since it would take an abundance of water to get it to waste out the bottom each time. The ProMix can absorb a ton before it is draining through.

Do you have any experience working with bigger containers? And how did you manage it?
