Well it's a bubbleponics system, so I can't really make it any smaller haha. I was thinking about putting in an external res. and just putting them in a shorter grow space but I don't know that doesn't seem like a good idea because of less root space. 3 or maybe 4 should do alright for me to have a decent personal and maybe get rid of a tiny bit as well. I should be able to improvise the space a little, as there is some duct-work in the way along the ground, but it doesn't rise above my ponics system so I probably actually have 42" length and width.

We'll see soon though, just started germing my first AK's :]. Got three in a paper towel as we speak.
