Alright cheers I thought they may put out less that’s ideal then. Found a huge one for a decent price so just need to check with manufacturer that it can be used with an external humidistat

Was looking At those bud but they don’t say the output in ml/hr so I can’t work out if they produce enough to produce more than the ac units are taking out

The space isn’t that big maybe 7m x 7m x 2m. It’s a completely sealed room so it’s all about the amount the ac units remove I guess. I have a 50l dehumidifier which works more than enough for 90 plants

Yeah I’m looking at those on house of hydro. But I don’t want to buy a 12 disk one if I only need a 4. And I don’t wanna buy a 4 to find out I need a 12 As either way I’m wasting money if you know what I mean. Do you know how to work out how much an ac unit removes?

Anyone here know anything about this?

My grow room is now sealed with co2 and I have dual hose portable ac units going. At the beginning stages of growth the plants aren’t producing enough water vapor for me to get vpd in range. My ac unit says in the description “max dehumidification 1.3l/h” I have 3 of these ac units. Do I...

That’s insane .. we get ripped off here

Yeah I’m in Europe I paid around 5.28 usd per strip but the aluminium bars ... The smallest aluminium bar I could get away with is the 20mm x 20mm and cheapest option is the flat bars. The aluminium flat bars would cost me 3 dollars per meter. So 1 dollar per 1 foot strip. 400 usd for heat...

Does the rockwool hold enough oxygen or do they need to be allowed to dry out at first when rooting?

Cheapest I’m coming up with is a 4 inch wide 2 inch sides sticking up, 1/8 inch thick for around 83 dollars. That’s for 5m length. It’s bloody extortion Problem with that though is I end up with 4 strips on one u channel but the strips won’t be equally spaced apart then will they? It will be...

They are very expensive here though. I’d be paying more for the aluminium than I did for the actual strips. If I absolutely need those though ill bit the bullet and buy them but 400 1ft u channels sounds insane

Flashing is 0.6mm thick. Yeah I got the one footers The flat bars Would probably work out a bit more expensive than the flashing but thicker. My understanding though is that thickness only helps with spreading the heat. Since they are bars the heat has nowhere to spread to anyway. So...

That’s the issue I was facing in regards to the power/heat issue. If I run them at max around 10w each and have the strips on alluminium flashing how many strips could I put on that aluminium flashing before the heat is not dissipated fast enough? Theoretically I could have the strips...

Quickly read over that and from what I can gather the verdict is they are small and made for low current so not ideal for large areas? But I’ve bought 400 of these strips. Low current low power but more strips per sqft and you have a very efficient powerful rig? No? My cob setup used a...

I’ve never used rock wool before or nft. I just got this NFT system for free to test out so I figured I’d give it a go . If it works out I may use it for my mother plants going forward. For anyone experienced with Rockwool or nft are my blocks too wet? The water is sucking up maybe about a...

I bought the q series as I thought they were the better efficient strips. Also because they are the only strips I think I can get to work on the 36v drivers I already have

My thoughts are to stick the strips to the flashing with thermal tape and use a timber bat around the end of the flashing. Two timber bats with the flashing inbetween screwed together to keep the flashing in shape. Each piece would probably be 60cm wide by 2.2m long. With two pieces of 30cm...

Could I get away with aluminium flashing? 0.6mm thick to dissipate the heat of the q series leds? I’d have the strips running 10w per ft and 30w per sqft on the sheet metal

The specs of the driver say that the voltage will automatically adjust to the requirements of the cobs I believe. It’s a bit complicated and I struggle to understand it but something along the lines of constant voltage until a certain point and then it switches to constant current

I don’t know exactly as I’m struggling to work out how it will work but I will be using 36v 600h drivers The data sheet says input voltage 10.9v and max 900ma I plan to run 18 parallel strings on my driver with 3 strips in series on each parallel string. Which should get me around 10w per strip
