The clone rack that looks like this and has 2 or 3 inch clone collars comes in tent sized kits. You just attach it all together with pipe dope. Can save space and do lots of clones. And it just runs continuously. Pretty sure you could make a setup for about 100 bucks including the 25 bucks for the cloning collars. Unless your hardware prices are insane too. Here they are pretty bad.Anyone ever try this? Works awesome with strawberries.
It's a fill & drain system with a bell siphon the end of each level.
