Isn't that when you just pop a water pump in the control/header tank?

Yeah, it's possible I could do that intake from the Attic? I just hate the noise and welcome the idea of the Venturi.

What about mosfet etc? Also, setting as light gives you way more range.

Just going to have a look but check out my new thread on here will ha please @DarkChild758

Hey people, I'm sick to death of the noise of the 80 litres p/m air pump noise and cleaning the diffusion rings so I was thinking of going down the Venturi route. I currently use 6 or 8 40-litre/9-gallon buckets/pots with the same size control/header tank. I was thinking of getting larger...

Is that all I need?! What coding and other bits do I need to do? I use ESPHome. Also, wouldn't the voltage only be 5v?

What’s a RC filter please? Bought a couple of cheap PWM to 0-10v and was powered by the board at 24v (12v didn’t make the range). One was so so, was about 5-10% off and that could auto turn it off. Bought a i2c 0-10v 2 channel DAC from DFROBOT and it works perfectly in Arduino IDE and hardly...

Has anyone got this running with LED's also yet?

GO for Atlas Scientific sensors. Spot on but not cheap. Middle ground is DFRobot then whatever was linked above.

Well im only going by what Lumatek told me on the phone and via email that its analog 0-10v or CCR or something.

I have one already but don't know how to program it in ESPHome as a custom component as it's not included in the ESPHome library yet! I've been trying for ages but I'm not good at all this.

Nope, not yet was worried something might happen. Im going to try this afternoon though.

Cheers, Ive looked everywhere but their drivers are made in-house and was told by them it wasn't PWM.

Hey all, I have been trying to get a 0-10v analogue signal into the ballast so I can control it via my ESP32's and Home Assistant. With Meanwell drivers its simple, just use a PWM current but I called Lumatek and they said its 0-10v analogue dimming and not PWM... Well I have an AC Infinity...

@javawizard Would this work with the AC Infinity lighting adapters also? I have a Type A one for my Lumtek fan so was wondering if I could use with it also?

Hey all, I did my last grow about 5 years ago at my old house. Was a converted all-in walkdrome, amazing I got rid of all the gear and then sold the house (my ex at the time didn't like a weed so it was on hold). Broke up with her bought a tent, 2 x Gavita 1000w 400v, AC Infinity, Alien...

Yeah, it's just quite hard to make out some photos. My idea which I think is the same is to have an air diffuser ring in each pot and also either have a large lump in the header tank which goes to each pot with a venture injector. Either that or im going to follow yours and not use Venturi and...

Well, this can get deleted when it does, I'm a genuine user and more active with 500+ posts on the 420uk forum, I'm in the UK and only shipping inside the UK. I've been a member on here for like 10 years or something, or that might be THC talk. I sold my brand new Gavita 1000w DE Slim for the...

Oh yeah true, just I have a brand new Hydro kit for sale at about 20% off. I never ended up using it and have decided to build one myself, I have NO idea why I didn't do that before, I've got all the tools, and most of the knowledge and can work with most places in houses as I do some security...
