Its been a lazy 3 or 4 days here. I did manage to get the top-off reservoirs setup and tied in finally. Anywho, here's what I'm battling this week...
Res Temps... I'm hittin 79-80F in both systems and its got me super sketched. 6mL/gal of UC Roots per change, then 3mL/gal every 3 days for maintenance. During res change & system clean there was some brown shmag on the bulkhead pipes, and a bit in the corners of the buckets. First I thought it was root rot or algae but given its consistency I think its sediment from the hydroton. Found brown hydroton flakes as well. The roots are white still... Not mega white like I see other guys, but my nutrient fluid has a slight brown color to it to begin with.
I'm going to pull a ghetto move and try x2 frozen bottles in the epi center so long as it doesn't displace too much. My VPD is dialed and low as I can get things. Temps fluctuate between 74-77F and humidity is @ 68-70%. Hoping once I have a canopy and some shade over the system & plants start drinking more I'll be able get the temps down a little. There's used chiller online, but that's a 1000 KM round trip drive and $300 each. Fall/winter is also coming so that will help things out big time. My overnight temps are only getting down to 71F so the buckets aren't cooling down during lights off given the insulation. I'd hate to dump a grand on chillers and not need em in a few weeks time...
Calcium Dust? I'm using a 10-disc ultrasonic fogger panel inside a rubbermaid tote with a CPU fan as my humidifier. It works amazing, probably burns 1.5L/hour though.. Problem is I've been using my municipal water to fill the tote up. I now have what I'm assuming is calcium build up on the tops of the pots...the panels...f****** everywhere...starting to us the RO now. Never had this issue before at my old place. Same water system.
Light distance... Unsure what to be running these panels at for height or dimming. I know my CMH's fairly well but I'm new to these LED's. They are a nightmare to adjust the height on them given each corner has a yo-yo. Lower one corner too much and it twists the shit outta the panel. No bueno.. I had them set @ 4' high, running 100%. Looked like the CMH were catching up so I just dropped everything to 3' above canopy. Idk if I'm shorting myself big time on the potential given I have no par meter... The CMH plants are super perky and look awesome, but the ones under the LED look "heavy" for lack of a better term. They aren't drooping, but only a few of them are looking on point.
Air Stones are plugging up in some of the buckets. I bought the cheap vivosun units of amazon and its weird because some of the buckets are rocking with bubbles, and others aren't. Tried soaking them in 29% h2o2, then boiling them, still f*** all for action. Ordered a bunch more regardless.
