ideal system for 3 plants?

well currently I'm using dwc in a small 2x2x3 box, I'm thinking on buying a small tent 2x2x5 and using the other box for veg while the tent will be used for flowering. I'm trying to think what would the best hydro setup would be for tent. I can only have 3 flowering plants at a time so that's the reason for that number. Should I just build another dwc system or maybe buckets? Also would there be any problem if I just pull out the plants and place them in the new system?

just go soilless in 3 gallon pots top feed 3-4 times a week or when needed.

Have you ever heard of Hempy Buckets. They look to easy and hard to mess up.

I use a Low pressure aeroponic system for 3 to 4 flowering plants and another small cabinet also equipped with low pressure aero. Personally the results I've obtained are amazing to me and my close friends when some one comes over they always think they should be half the size they are.

an aeroponic system is an option. As for Hempy buckets, I'm would think the plants would have an higher chance of shock during the transplant than that of other methods.

3 bubble buckets seems reasonable.
