3 gallon buckets instead of 5 multi air pump run up to 8 buckets per pump !

I 3D print my mason jar lids so I can put humidistats right into them. I do have some check valves and aquarium line here, I think I have a new project… Slight modification to the lid should easily deal with input / output lines.

amazing idea. perfect for the small grower run input line to bottom of jar forcing air through jar into the exhaust valve

how big are those sensors? I Like the app side of it and the fact you can have 8 sensors…
Hmm… wonder if they integrate with home assistant… need to look into that now…
edit: they have something for the weather station! thats promising… monitor tents AND cure in one place? sign me up (I can automate the burping with switches in HA as well)…

I use these. Love em.
I just walk up to the bucked and refill my jar. I write what’s in it with china-marker (grease pencil) on the outside and have a Bodeva pack rated up to 1lb inside there with a little hygrometer.
I never turned back after almost pulling a LB off of 1 Gelato 33 and getting annoyed at all the jar burping.

Jinxed myself. This humidity was not playing nice with bed adhesion… And I forgot the firmware on the printer I sent to doesn’t have “change filament” option enabled, so its one color (the overgrow logo should have been white).
Ordered 32 check valves tonight

you know you should find a way to get that into the market asap and make some fast cash. 5 lids for 20 bucks “without” humidity meter lol

Very nice!
If you put tape. I use duct tape, on plastics before drilling it help reduce risk or shatter.

I forgot how dangerous outdoor can be.
Heard something B-I-G was happening in the area, hurried over as soon as I could. Looking like a “Show of all Shows” is underway!! CONGRATS!!, continued success, do stay safe, take care, and be well…mister

Another tip? run the drill in reverse (especially good for holesaw holes in reservoirs). Same goes for cutting with a circular saw, reverse the blade, its less aggressive and cracks plastic less…

If this is plastic, try using a cheap soldering iron. Gets me the cleanest holes ever!

I prefer step bits to paddle bits when it comes to plastic.

Another good piece of advice, I have several in here (one in front of me now actually).
Step Bit - best choice, but get expensive above 1"
Regular drill bit(in reverse) - second best, most common option. Dull is better and must run in reverse to avoid catching an edge.
Paddle bit - worst choice, 99% chance of snagging and cracking. Strictly for wood IMHO
Regular holesaw (in reverse for plastic) - larger holes (1 1/2" or 2" usually but can go up to 6")
Diamond holesaw for glass, but having a glass drilling press is preferred (drill press with suction cup bottom). Any tilt to the bit once you break thru will crack it
