I would like to know why you would want to keep mothers in hydro in the first place? I don't see hydro as a place for mom's, some might, but don't you want low maintenance mom's?
to me, you are better keeping moms in coco or second choice peat.
this is also off the train of thought that I think of a mom as bonsai. mom's should not take up space, should not need high maintenance, should not need much, and should not grow fast..
E&F coco. Flat storage box, a couple pieces of tubing, a $10 pump and a reservoir to feed 'em.
I wouldn't use anything that will kill your plants in hours if there is a technical problem. DWC seems like a baaaad idea. Any medium-less hydro sounds like a ticket to losing your genetics.
Hmmm, maybe I'll convert my moms to wick ala PPK.
In 12 years I have retained the same mums in dirt, not the originals, but clones of. Recently I tried colloidal silver to reverse the plant and fuck itself, thus maintaining the strain in the event of disaster. It worked. Don't think I could have done it in hydro.
And I've read your entire thread at least twice. I don't doubt you could have done it in coco. Something fails in coco and you're now growing like you are in dirt.
But I'm biased. I don't like dirt.
it's hard to beat DWC for keeping a mother in. how about buying amesh pot with rim, a couple air stones and a nice airpump.
