I changed my system to a 5 gallon bucket. This is my next one. I mixed Reversed osmosis water and tap water 2:1.
my tap water high in ppms, mix according to your tap water. So I started my plants at 245 to 320 ppms and ph about 6.3ish. Had great growth during vegetation stage, then added compost to my water which brought ppms up to about 400after I had 4-5 sets of leaves. I said it's an experiment because they are not connected to my pond, I don't put this water back into my pond it has been ph'd and will hurt my fish.So i use my pond water and compost as nutrients for my plants. As water evaporates from my buckets I refill from my pond by hand. I'm just learning as I go and our next goal is a bigger pond more fish and trying to get everything working in perfect harmony. Any specific questions you got, just hit me up thanks.
