4x840W = 3360W @240V 3360/250=14amps @120V 3360/120= 28amps so ya you'll want to go 20amp at 240V because LEDs have a big inrush current when drivers first start up. And you don't wanna be checking breakers all the time. edit: or you can go 30amp on 120V but have fun wiring those receptacle...

Hahah Just like Savannah and mango

Drivers are usually around 88% to 95% efficient. The more efficient the driver the less heat you save by moving the driver out. so let's say a 600w driver is 92% efficient. Therefore it will waste 600X 0.08= 48w or 48x3.41 = 163BTU

Moving the driver out will save you around 150BTU. Even a cheap window AC is like 5000BTU. Which should be just enough for that grow. An 8000-10000 btu would be slightly better.

Another quality post. Will be following this with much curiosity.

are you sure the burner is turning on on not just running the pilot?

So how exactly are you cooling a 4x4 tent with a CO2 generator in it? That's a lot of BTUs to handle in such a small space. If you are venting to cool it then you are leaking. If you haven't opened up a window air conditioner and sealed the joints in side then you'll be leaking air that way...

I would skip the drywall and mud. I'd put a layer of poly to cover the wood. Then cover the walls with 1/8" PVC panels ($30/piece 4x8 sheet around here). Silicone the córners/edges and off you go. I used cement board for the bottom 3ft of my walls. But I did dry wall and mud. And kind of...

pretty much any 480w-640w led will do the trick in that space.

Looks good to me man!!

It's probably cold AF where he lives most of the year. So it will be a dead giveaway for growing or other illicit needs. other reasons to have AC: Server farm Bitcoin mining op

My tap water is 7.5PH and 0.7EC. If you have an AC and dehumidifier you can mix some of this 0EC condensate water with your tap water to bring it down to reasonable numbers. You can get RO but you will be changing your filters frequently not to mention the huge waste of water those systems are...

hide the AC like this maybe? Or a fake looking chicken clip or anything that makes sense where you live.

Pretty sure I got pekacid based on your advice. I bought a $100 bag and it will last me like 3- 5 years at this rate. It's awesome shit.

How much agsil do you use per litre or gallon?

How much do you typically water? min a week my room usually uses between 216 gallons and 300gallons a week when packed. It ends up costing a shit ton in nutes and additives lol. So I try to run the least complicated nute regime cuz I hate measuring and mixing and checking PH. I use floraflex...

You know when I was building my room I was asking a lot of questions on here too. And I changed my mind a lot on what I was going to do. But I am really happy with where I ended based on the culmination of other members opinions and my own experience and of course some math/science to make sure...

I am more interested in the Si for strengthening the stems and making the plant tougher as Bugby puts it. Some strains I got feel like could do with thicker better branches.

Also is it better to apply silicate foliar or to the pots rather than mess with the resevoir?
