Things to consider for sure, I'm sure there are ways to mitigate the risk (how do comercial systems work?). As long as you don't set it up in a way that it can siphon out from the tanks then I'm sure that leaks would be minimal. Maybe a one-way valve (to relieve vacuum) could minimize contact...
ok awesome, thanks for the info. Is the system controlled via arduino? is there anything in the mixing tank doing any mixing or is it just the temporary tank before you feed (I was thinking one of those magnetic flask mixers would be cool)? have you considered making anything to agitate the nute...
I'm curious what sensor you're using for ph and how long it will stay calibrated, also are you using drippers? do you worry about clogs? do the liquid nutrients separate at all over time? (from sitting)
Do you have a component list or do you want to keep it under wraps? My buddy and I have been talking about this and I'm very interested in making one, I have experience in code, arduino, rpi, etc so it should be fun.
Yet again I will say its been a while and as usual my one blueberry has issues im dealing with. But the cheese is a beast. Also I've got 3 sweet skunk started, they are stretching a bit, despite being fairly close to the light. I was gifted some bag seed that I might play around with too.
Update, everything is seeming healthier and bushy, just waiting for the auto to flower. Also I received some seeds yesterday for my next grow, where I will attempt to make seeds
