How much electricity hydroponics use?

How much electricity the pumps use in 1 day, 4x4 tent?
My 25 watts carbon filter is working 24 hours/day, 1 day it uses 24*25 is 600 watts/day. But I don't find that information for hydro pumps!

There is any difference between pumps make a lot of noise and pumps do not, except the obvious difference, the price of them?

Just like the carbon filter, pumps, fan, chiller etc. all have a watt info on them or they should have, therefore just like the math in relation to the carbon filter, you can calculate it, better yet get a watt meter and see whats what.

Eg. lights, my 150 HPS uses 171,2 watt. according to the watt meter, you can sometimes be surprised...

The pump should have a wattage rating. If it only has amperage and voltage ratings just multiply them for wattage.

The power used by my water pumps is tiny compared to everything else, 5-10w per day isnt worth worrying about.

I use about .045kWh per day for the hydro part of my grow on each 30W water pump.
My water gets injected through rain jets so gets oxygenated on application and waterfalls back into the reservoir.

35watts! My aquarium air-pump was only 3 watts.

35 watts only for 1 plant?
Aquarium pumps are pretty low users and I never even think about the power they use. The ECOAir5 pump I bought to run DWC with sucks up around 120W but cranks out 1300gph and should run for a decade without worries where I was always rebuilding the aquarium ones or buying new ones at $40 each for a dual outlet unit. The ECO Air was just over $100 and does the work of 4 or 5 of the others. I've been using it to aerate my dugout all winter. lol

Lights are what cost the big bux to run. It costs me almost $100/mth to run a 1000W light 12 hours/day as our power is very expensive at almost 25¢/kwh.

The computer I'm typing this on uses 160W and is on near 16 hrs/day. :)

120W is a lot. I think I will not change to hydro yet.

A laptop uses only 20W. I prefer a laptop because of that. Since I started growing I'm very careful with electricity bill. I need to buy a house and will have a 750Watts computer and no more soil. I will have the perfect temperature and perfect humidity.

You can naturally go for a smaller wattage in hydro, of course depending on your setup, I recently set up a system NFT at my cousins house, a 740 gallon pump at 30 watt, and that pumps really does the trick, so it doesnt have to be that expensive, but everything is relative...

My computer has a 650W power supply but only consumes 160W when it's running. I have one of those watt meters I used to see exactly how much power it does use. The power supply is rated for what it can put out not for what is used all the time. If it used 650W I'd go get a laptop. :)

Are you concerned that high energy use will alert the power company that you're growing pot? You really have to go big time for them to notice. As long as you pay the bill on time they're happy to give you all the power you want. We have a small acreage/hobby farm that's wired for light industrial and no smart meters here in Alberta either. The only thing I worry about is coming up with the money to pay the bill. lol

I don't think there is any need to run such a strong pump, the 30W pumps I use do 1000gph, but they won't be able to push it as far uphill as the fancy 120W pump, but that is not really a parameter that is at play in DWC,

Also, find out how long the pump needs to run. Running a pump that is submerged full time, will heat up the water. You could also use an external inline pump if you could find one.

If noise is a concern as far as airpumps go, just bolt them down to a cheap-o stool or small end table. Reduces my 110LPM air pump's noise by at least 50%, maybe more. As far as the electricity usage goes, I think that's really going to depend on what kind of hydro you want to do. Will you be doing RDWC, standalone DWC, or another form of hydro?...Standalones only require an airpump, and to some degree it would reduce power usage compared to RDWC where both an airpump and water pump are needed. In any event, I don't think that it's going to cost you much extra $ at all on a monthly basis unless you live somwhere that electricity is very expensive...wish I could help more, but I'm not that electrical savy lol. The increased yields should far out-weigh the initial electrical cost.

That 120W pump I mentioned is an air pump. I bought it specifically for a DWC setup I planned but haven't set up yet. 4 individual tubs with two airstones each. Came with a manifold with 8 valves on it so just what I needed. Should be doing that by this fall.

I hang my air pumps up with a spring or bungee cord to absorb the vibration. Still noisy but such is the way of air pumps. Noise isn't a concern for me as my grow is in the basement but annoying when I'm in there working on the plants. Having them up higher than water levels is a good thing too.

Some of that silicon air line works good instead of a bungee cord too.

Possible will start only with 2 plants with a DWC setup and will only need a little air pump, not a water pump.

I should live in a small farm... A small farm in the countryside cost less than the apartment where I am. And I can live their because I work online.
The country I am from, not a big problem if I am caught growing weed, but is against the law, I cannot grow 1 plant. I always try not use a lot of electricity. But in reality I think I could use a lot more, some people have graphics cards running 24h mining crypto, some people work from home and have AC working all day.

Hotglue 3 compression springs onto a piece of mdf in a triangle pattern and sit the airpump on top. The springs will absotb the vibrations that would normally couple into whatever the pump is sitting on.

All sorts of reasons to have higher power use than average. In a town called Maple Ridge in BC years back the authorities came up with a sneaky method to hunt down growers. The went thru electricity bills and any that were really high they showed up and demanded to do a home inspection. Out of the 100 or so places they did this they only found a couple of pot grows and the rest had a hot tub and even electric pottery kilns. Some were growing veggies in their basements. They would still hit them with a bill for a couple of grand. So much shit was raised they had to stop and return money after a big court case.

BC started changing over to smart meters years back that track usage second by second and many devices like some digital ballasts along with many other 'smart' appliances actually identify themselves so they know when you make toast in the morning etc. They would just show up and switch out your meter without saying a word. Same thing in Ontario and many states. End up paying a lot more for power and many of the meters were faulty and houses were burned down.

The guys growing big were tapping into the power lines and stealing the power for lots of lights and that was one of the main arguments for smart meters in the first place. First there was all sorts of propaganda in the media about power theft and the dangers of grow-ops with unauthorized wiring. Not to mention the danger to children from bad wiring and dangerous chemicals used to grow pot. Save the children! lol

In truth there was a lot of illegal grows run by both biker and vietnamese gangs where they would rent a big house and gut the insides growing pot in every available space then stick some slave in there to manage it. Mould everywhere and a destroyed house with the owner stuck with the bills. They applied that model to even guys with a few plants so now if your home is identified as having a grow in it you can't sell it without paying thousands of dollars for testing and remediation. Big business for companies doing that. Then it's hard to get a mortgage or insurance for that house.

The general rule was that you can run an extra 1000W for each bedroom in the house without attracting attention. This 'smart' world we are moving towards is removing the last bits of our privacy. My 2005 Chevy Malibu has On Star in it and even tho I don't subscribe to it if the cops were interested in my movements they can still get that data from On Star as it's still tracking me. I need to figure out how to disconnect that damn thing. Not that I'm doing anything I need to hide but who knows what I may get up to in the future. ;)

Next is the cashless society so they can track every penny you spend. As it is when I go to the city to do some shopping I take out what cash I think I may need and pay cash everywhere so they don't know what I spend my money on. Especially when I go to the hydro shop. lol
