Good one mate thanks, yeah I can't see the money in what they want for a Cannatrol they want 4k+here.

mp I wonder how a meat curer would go, way cheaper than Cannatrol, you only need to dial in temp and humidity, actually, I might build a box with some controls on it I don't think it would be that hard to do, heater, humidifier and small exhaust fan with a few sensors, I need to do something...

Got to throw in the greatest entertainer of all time.

A timer has a rated current, most in Aus are 10 amps which will handle at max 3 600watts lights or 2 1000 watt lights, so long as the load is under the timers 10 amp rating there wont be a problem with the timer, the thing with lighting is the startup uses more amps and then lowers to its...

You never overload a circuit doesn't matter how many appliances are on it so long as your not overloading the circuit breaker you're on, that has nothing to do with running a contactor to take startup load off the timer when it clicks on to fire up lighting.

The thing with timers is they have contact points and when pulling high amps those points get like little weld spots on them that can cause them to get stuck on, best method is to have a contactor take the load and the timer just turns that on and off never have a problem with overloading a...

I do but an 18hr day means 6hrs are in the heat of the day, I still have to vent with full airflow at nighttime just cant gas in a closed room as our nights are still a little hot, but fine for full venting at night.

Just an update. Got it all setup and working, the problem Ive had is my small aircon struggles with all the lights on when its really hot outside, we are in summer now, anyway what Ive done is have the aircon, humidifier and gas on with 1/2 the lights on for 6 hrs during the heat of the day...

Youre not saying what the humidity is that you are bringing into the space, at best, you can only equal that with airflow, you can bring that down or up slightly by regulating your temperature, but in an open grow with a lot of venting in your room you are governed by outside humidity. In veg...

Divide your voltage say 110 into your wattage 2250 and youre pulling 20.4 amps. on a 240 volt system youre pulling 9.3 amps.

Aus we are 240 volts our circuits are 10amp standard. I guess its just same volts divided into watts to get the amps.

You understand a space heater will pull 2400 watts, an electric kettle will full 1800 to 2400 watts, clothes drier will pull 2400 watts, which is all the rated max of a normal 10amp circuit, the problem is how many outlets are on the same circuit, growers will set up a room and everything runs...

The dimmer just lowers intensity the spectrum is the same at any power setting.

The window aircon I have is only 1600 watt maximum cooling, its small 450-millimetre square about 18inch I can pick it up and poke it in the hole above my head, yesterday it was 30 celsius outside and inside the room with lights on the aircon easily kept the room at 26 celsius, enough so that...

Ok swapped out the units and it seems to be doing the job while turned down, the other one was faulty it was full cold settings and couldn't do it.

The room is 32 celsius inside lights on, I have the gate-vent on the aircon closed so it recycles only the air inside the room as it is sealed with Co2 gas, the rear in the other room of the aircon is 40 Celsius, I have it set to get the room down to 27c but it cant get under 30 as the...

Ive had plants do this cupping indoors in all sorts of medium and have taken those plants outside give them the same feed they were getting indoors and they straightened out within a few days, I think its something going on with the roots and the way they breathe, indoors is different, I still...

I have 2000 watts of led lighting running in a 10 x 10 insulated sealed room , online calculators say that is 6824 BTUs https://www.unitconverters.net/power/watt-to-btu-it-hour.htm My question is do I need at least the same capacity aircon 2000 watts to keep the room at the right temperature, I...

Yeah same here it gets real hot, I run at night which helps but Im in the process of going sealed room and aircon, my walls and ceiling are fully insulated so I think with aircon and being sealed summer temps wont be a problem.

VPD does matter a lot, especially if you have a lot of light on them its relative to demand, the more light the more anything wrong will show up, plants grown under low light have little growing pressure on them, its why in a jungle everything is so lush deep green , low light high humidity warm...
