Evening all,
Bit of an update, but more notes and observations as I puttered away at retro fitting the system, it’s been slow going, have had a head cold or something the past couple days and breathing has been no pleasure and wear out easily.
Part of the retro fit required a refit of the reservoir halo ring as well. It was originally 22” in diameter but had to be shrunk down to 17” to make room for the larger return pipes. While I was refitting the halo ring I decided to make a shield as well to minimize foam oozing over the side.
Here is a picture of the reservoir top with riser and halo ring
The shield extends into the solution keeping the foam contained. The arrow is pointing to a valve that allows me to adjust flow by bypassing up to about 20% of the flow from going to the buckets.
As of this morning, I have 3 of the buckets retrofitted with the new return pipes. Having been shut down for a couple days, it started going septic again so I decided to fire it up and let it run full flow to get things back into aerobic conditions.
At startup, it was reading 69.2F and after 3 hours it had gone up to 71.8. Not quite 3degrees an hour. Ran outta energy so I am going to leave it run wide open until morning and see how much the temperature rises by morning. If it climbs higher than 72, I will try running it at 2hr on/ 1hr off and monitor temps. Until I get my DO meter, I want to run maximum aeration but balanced with temps.
BTW, all buckets are staying at the same level as the reservoir, even at wide open throttle. 1 small step, but success
While I was returning the system to aerobic conditions, I thought I would check the pH, even though I am still waiting on calibration solutions. Having gone septic, the pH also rose to 8.4. I checked again after running for a few hours and no change so I decided to give it some lemon juice and check results. 1 quart of lemon juice brought the system down to a stable 5.9 after about 20mins.
Although I am hoping the plants regulate pH like they would in LOS, should I feel the need to monkey with pH, I will be using lemon or pineapple juice as pH Down and hydrated lime as a pH Up.
Things are coming together and seeds will be dropped this week, with seedlings being introduced into the net pots the following week, time to get some green growing
