SWC, the next level
I am wondering if Raybo's combo mix for SWC will work for a large SWC. I want to make a full size 4' x 8' raised bed with large reservoirs. Will that mix work for a large area?
Also would like to make the mix from scratch instead of having to purchase too many bags of potting mix. I would buy material in bulk to make the wicking mix. I'd like to make several 4' x 8' beds so I will need a lot of mix. Any ideas?
