Holy Crap Buds! As I posted this reply, I saw your post! So sorry bro, hope it all works out. My prayers and positive thoughts are with you.
I have gravel over the chicken wire and a sheet-metal ring 1 inch higher than the water line. My mistake at first, was not filling my center ring with soil. I misread Azi's link, and the water smelled stagnant. I emptied the smelly water out, filled my ring with soil, Bukashi, frass, worm-catings, perlite and a bit of dynomyco.
This is my start-up:
It took a while to reach, needed to top-feed them. Glad that I took it apart and drained the stagnant water.
This is what they are looking like now, my first SIP's
I made these rings out of sheet-metal for the drying nets-8 level. Buds got too flat. Now I am using the same rings every other day to feed the inner. Liking the results so far.
So, in answer to your question,
@Buds Buddy , my perpetual grow link is there soewhere under the rainbow.
Cheers!
