High All, Bubble buckets seem to be the new in thing at the moment. when I set mine up it was tough to find info, so with that said I thought i would get a tutorial showing how to set them up, This is not the only way, im sure there are many ways, this way does work and ive been running these for some time now, im in process taking down two flood tables and replacing with bucket set ups.. I go with 4 buckets per res to keep the perpetual garden, it can be expanded by all means, run more or less is fine, just make sure your manifold pieces are the same to get the flow equal with all buckets... The res size is up to you, the bigger it is the less it will need to be added to. Im in the garden everyday so filling every couple days is fine for me.. As a few of these steps would be easy to do with a router or some other devise Ive completed this with what i think everybody probably has available and at hand. other then the 13/16 paddle bit and the plastic de burring tool i dont think most would have to buy any tools. the ph is 5.8-6.0 in hydro and applies here also.. the water level 1" below the net pot to start, try to never get it closer then that but once the roots are in the water lower is fine, as you can imagine it will decrease daily..
