The line itself to me isn't the best choice unless u r hand watering. I don't have enough experience with large reservoirs but even crazy mixed in my watering can
nftg separates. I have been messing around with aloe juice as of late and find it kind of acts like an emulsifier and keeps the
nftg suspended longer. At least long enough to water a plant completely. Can't see it working to we'll for any long period of time though. Just thinking out loud here but if I was going to go organic in a res I'd use nature's nectar. Mixes as well as if not better than any synthetic nutrient line I've ever come across. Works really well too. Good luck brother.
