I’ve noticed anecdotally that plants growing in sand smell better and smoke better!
I first learned about IAVs sandponics a couple years ago. I always wanted to do aquaponics but it seemed a bit intimidating having to constantly monitored things and all the PVC needed. Aquaponics is often described as a balancing act and I describe sandponics as balanced.
About 10 months ago or so I bought some tilapia minnows off eBay. It was 25 fish I ordered and I lost about a half dozen that first week.
I live in the high desert and dug up the sand right from my yard. About one foot down is mostly a really coarse mountain/river sand. I took that sand and washed it with the 5 gallon bucket quite labor intensive just pouring the clay and silt off the top.
I eventually had enough sand to fill a under bed tote about 3-4 in deep ridge and 1 in deep furrow. I planted carrots lettuce peppers all kinds of stuff and a couple cannabis plants. I run a perpetual grow most of all my plants are in a peat-based soil mix. For every 10 plants in peat maybe I have one or so growing in sand.
I’ve noticed harvest after harvest about five or six in a row now that the plants in sand vs peat are notably better. Keep in mind this sandbed is only 3 inches deep and I’m growing autoflowers. Because of this shallow sand bed often these plants that don’t get too big. I don’t know honestly if the yields are better in sand specifically the stank is way stinkier.
Yesterday I rubbed one of the plants and sands sugar leaves and it smelled like straight shit and gas. That was the first time I ever smelt that rank of a smell. The other one I smelled was really like a delicious candy.
I don’t think it’s a coincidence that the plants in sand have a more complex scent consistently.
I have absolutely no evidence to back up what I’m saying this is all anecdotal. I’ve been just popping Auto flower beans that I’ve made over the years.
Hopefully one of these days soon I’ll have a few extra clams so I can order a full truck load of concrete sand.
