Yes, but $30/per for the smallest one.... No thanks.
Honestly, as of now I split between top water and sub water. Getting better at wrangling that cover without abusing the seedlings. My mix is pretty peaty.
My planter size issue has more to do with moving them around. I have an oversized tent, with a mix of lights. As I finish up and remove my RDWC I have some plans to make a raised floor (floor is a bit cold) on a very slight incline with some pond liner to make the whole stinkin thing a giant grow platform that drains down into a gutter. This way I can move the plants around, take them out, rotate, and get rid of the damn pans
One of my biggest beefs with RDWC is the rigidity. X plants, no more, no less. With a bucket based system I can have the seedlings all close together, then move/spread them out for flower if needed. Rotate them around the tent as they grow. I'm doing strictly autos with perpetual so I have various plants in all phases of growth. The volume is pretty similar.
I may regret going all-in on organic 5 gallons, time will tell. If yield is slightly reduced, I'll just grow +1.
The earthbuckets spill over if you breathe wrong, the opening and drain with the tiny trays aren't... ideal. With the buckets I can slap a piece of duct tape or a cork and swing them wherever.
I'm still enjoying the earthbucket though, just a little nitpickin'.
