@Growingkitten,
I'm am very inexperienced with growing and especially RDWC (first timer!) so I'm not sure what I can say about GHE.
I sure don't have any complaints !
Everything is going really well and I'm totally in love with RDWC cause:
- no bags of soil
- no bugs (also cause I grow from seed ofcourse)
- EC/PH easily measured
