From what I understand they have to be Palm and Fern sticks. Which I can't find for the life of me. If you can use the others I have 100 I just bought for my wifes houseplants.
Any updates here? I just tossed anubias in my 20g and I'm makin room for more plants. I happened to already have some jobes spikes. It would be sweet if I didnt have to shell out for some expensive root tabs.
On an earlier post (cichlidcichlid, !2/01, "Can You Ferilize Roots with Liquid Ferts?"), Plantbrain (Tom Barr) mentions something called Osmocoat, which you might want to follow up on.
