I would say it’s doable... but wouldn’t recommend it
mainly because I don’t like growing more then 1 plant per reservoir
when it’s just the one plant problems are more simple.. you don’t get tangled roots, water is easier to keep good air flow, if a plant gets root rot it’s easier to combat and it’s limited to the one plant, generally more space per plant, but I’d also say that different strains like different amounts of nutes too.. but give them proper air and water flow nutes could be balanced out between the bunch.. idk I’d say it’s risky for no benefit..
you have to way the pros and cons of it.. and if you can’t find a better and more practical alternative then go for it but why crawl when you can walk
