weird. Maybe aquatic bacteria is different then soil? I use earth juice pH down and it's pure 100% citric acid according to the MSDS sheet. Haven't noticed issues.. but then I amend microbes pretty heavily.

yeah that's what was confusing. Was dealing with flickering when the lights were on... then while it was plugged direct and not on... it came on after an hour or so. The main issue is the power supply's have some wifi functions built in and must be borked and flipping things on/off...

Yeah I checked connectors first. one works fine and the board works fine when I swap them. I tried to power them up with an extra meanwell ps but the output was like 91v. Having a timer will mitigate turning on randomly since no power will be going to it but still sort of unnerving. I still...

I had no timer on it. It was plugged directly in. I suspect it's the ballasts built in wifi that's the issue. I have fluke meters and lab equipment at my house fwiw so I know somewhat around electrical issues.

fwiw I bought those $25-35 Bozily lights posted recently. I had issues with one of the ballasts. When on.. one of them would blink randomly and when off the same one would turn ON. (make sure to check your lights during lights off) I messaged the seller and within a day they requested a...

it's over 1 1/2lb and Mykos WP is only 250 prop/g and Dynomyco is 700 prop/g ... so not so comparable.

not sure if they ship to Canada but something like this? https://oregonsconstantgardener.com/collections/ocg-nectar-gear/products/nectar-fam-uv-protective-arm-sleeve

I thought it sounded a little light on u/mols for flower but not sure what their objective was with the study. I think this is one of those cases where people are trying to be too smart. and yep.. I will not run UVB w/out heavy UVA. been there.

appreciate the non-copy pasta but did you read the study linked? Same study posted earlier in the thread. apply long-term UVB .. burn shit.. lose potency.. the more UVB, the more breakdown. UVB will break down all organic matter eventually. This test does not apply to triggering a response...

Long-Term exposure to UVB will break down material irregardless to what it is. Sounds like they were testing UV for photosynthesis vs. triggering a response. They were also using UV LED's which aren't as effective as tubes. (for UV) The severity of UV-induced morphology (e.g., whole-plant size...

can't answer for something I haven't used personally but seems logical. I think there's more to it though like inline hepa's and certain airflow requirements. Just hepa's should remove spores though. could be wrong

You want to keep any UV away from flower after chop. UVC not good for terps / cannabinoids.. or anything else for that matter outside of sterilizing. If using UVC to sterilize incoming air,. only way to do it safely is a duct setup where air passes over UVC similar to hospital setups.. so can...

If you have spare emerson strips.. you can block off the 660. (I used duct tape) Don't have to worry about heat building up since it's only on for minutes. You'll only need to convert one of the strips to cover a pretty large area.

details? what part? or you bagging on light movers in general?

I'll play. drop the power from above, use electrical slip rings, put a small tower fan in center of tent which spins 360deg and mount vertical light strips to it and power from slip connector above. Get equal side lighting while also gaining under canopy air movement to all your plants. Will...

pull the doors and put up a panda film wall around the frame with a zipper door if you need it.

that is the weirdest application of a coupon I've seen. Had no hint of a coupon / discount until you checkout. Now wtf am I going to do with all these damn lights. lmao thanks!

Apera has flat sensor pH probes that are much more durable/protected but you end up losing TDS (If a combo probe is being replaced). I can still use the TDS sensor on the original combo probe if I ever need it. Seems pricey until you replaced pH probes a few times cause you broke them tapping...

Gardening was my therapy before I got into cultivation. Cut my teeth in peppers and plumerias. I originally got into gardening due to something my doc said about finding another hobby that I can positively apply my mild ocd to. That was over 20 years ago. Since I now own a home, I grow...
