dude, you got this! ur crazy awesome sideways starship tent is turning out brilliant!
what hydro style you lookin into? just wanna throw a tip from what i learned here about choosing the appropriate style for the size of ur grow. with 4 plants or less in 2 reservoirs, the tote bubbler DWC is great. beyond that, the RDWC systems would be my choice. far more efficient and less maintenance than several individual reservoirs. ive read and heard that flood tables are good for bigger grows like yours too. however, you WILL lose more vertical space with the larger systems than you would in soil pots or bubble totes.
good luck!
