Thanks Stan,
I’ll be flushing the system today and I’ll add in (separately per your instructions) some Epsom salts. You mentioned in a previous post “…maybe 3 tablespoons once a month”, is that per my ~ 16 gallon reservoir, or per gallon of water? I removed the last neoprene collar and added hydroton around the stems, do you think that will still constrict the plants? My intent is to block out sunlight to prevent algae, but I doubt that’ll be a problem this time of year. Just a note on the
pump timing, it remains at 15 min off & 3 min on, 7/24, and the plants seem to be OK with that, so I’ll leave it be – though I do have an additional timer to run the Spartan® timer. I custom built a panel to house the four timers so it doesn’t look like the wiring in the Griswald Christmas vacation movie! I’ll post a pic when it’s complete. And... that video was awesome - I'll be the "bee" for now, though I have actually had a couple bees wander in when the garage door is open.
