It could all be in my head, but I’ve always felt that soil/organic stuff just burned smoother and tasted better. As I’ve grown more plants, and really, as I’ve dried more plants, i think the moisture content of the flower has more to do with the smoothness and taste. I’ve tried some really great salt grown flower, as well as really great organic soil grown stuff… I think there’s so many variables at play there, it more comes down to the skill of the grower and the cultivar, rather than the method.
Pretty much what I’ve been doing, I run 5 gallon rez with airstones going all the time, and a pump on a timer in the bottom to occasionally mix the tank. I use a paint mixer attached to a drill to mix everything initially, and end up with a little sediment. So far so good over here with dropping the Epsom salt, I’ve been feeding the mothers the same mix as the flowering plants and they are not showing any deficiencies yet.
Once you get the routine down, it’s really easy. Just like following a recipe when you’re cooking something, you do it enough times and you don’t have to follow the recipe anymore, you just kind of know what to do. Luckily, when I mix up everything, my pH comes out at 5.3ish and gradually rises, so i rarely have to bother checking pH (though it’s good to initially check). It’s definitely cheaper to grow using salts, i think… I can buy a 25# bag of Part A for $90 and 25# bag of Part B for $50… I could grow hundreds of plants for $140. But… I get the financial limitation, and it’s best to just use what you already have and the method you’re most comfortable with. I’m not trying to convince you to switch, just offering my perspective.
I do have qualms about the single use stuff… the coco is cheap enough and environmentally friendly enough that i don’t mind just putting it in the dirt, though I don’t exactly know how sustainable harvesting coco coir is, I imagine it’s about as sustainable as harvesting peat though, maybe even more sustainable. Also, i don’t like dumping the nutrient run-off down the drain, so I vacuum it up and use it to water the plants outside… they’re a lot more forgiving when it comes to pH and salts…
I’m surprised you can get away with watering so little late in flower, mine would be bone dry after 24 hours. You may want to look into high frequency fertigation with coco, if you haven’t already… Basically when coco starts drying out, the EC of the medium will rise, which you can use to your advantage (EC Stacking), but also, it can be obviously detrimental to the plant’s health if it gets too high and locks out stuff. If you make sure the pots have 10-20% run off each time you water (consistent saturation), you don’t have to worry about over fertilizing, you’re constantly flushing out the older stuff and it’s being replaced with new stuff… anyways, you may already know this, but here’s basically what I’m referring to, https://www.cocoforcannabis.com/principles-fertigation-feed-water-cannabis-coco/ - plus there’s a bunch of youtube stuff on EC stacking, etc…
Yeah, if you can’t keep the rez in the same area as the plants, it makes it difficult. I’m going to setup a system based on this guide, as I have most of the parts already, https://www.cocoforcannabis.com/diy-automatic-watering-system/
