My review is in my sig. You don't need an autopot reservoir, any large plastic container will do. I use a 45 gallon drum for my veggie grow, and it lasts for weeks. I just went with the single xl units with fabric pots when I set up my weed grow last winter - easiest to ship, and the best deal at the time. Don't do the double trays, stick with single ones. The doubles put the plants too close together and make for nuisance with LST.
If you want to do LOS SIPS, all you need is an autovalve for each couple planters. I have one valve feeding two >100 liter planters with vegies at the moment, and it keeps up easily. If you go for it, tag me and I will show you how to set up filtration. The filters supplied by Autopot are not that great.
