Found a youtube video on the sound test, but its a little hard to compare the sound to my situation tho.. But yeah, luckily they do come with a speed controller that has 8 levels. Just hoping level 1 or 2 will be very near silent in the box, maybe with some acoustic foam close to it.

Hey guys. Long story, short... i build a diy grow box 2x2x6, and was planing to use 3x noctua nf-p12. The pc fan has a pressure of 1.2-1.7mm H2O. I am just really beginning to doubt the efficiency when i add a Carbon filter. I havent drilled the holes for the fan yet, so i wont have to...

Hey guys. Doing a diy grow box, and im using pc fans, but i wanna find an effective way to use a Carbon filter. I bought 3 fans, 2 exhaust and 1 intake. My pc fan: Noctua NF-P12 High pressure, very silent. I was wondering, if this pc fan will even have a chance of pushing through a “normal”...

I do not have the fan, but heard a lot of good things about the ac infinity, should be super quiet

Okay, thank u. I think i will try and spray paint the vent black inside

Sorry, meant the fan noise from the build-in fan in the light bulb. Im building a super-stealth box, but need to find a way to light proof the 3 pc fans..

This is the box, so you have an idea of what it looks like.

Well.. i just finished building most of the box now. I basicly only need to do the venting thing now. I have sealed the box 99.9% now, and cant spot any light leaks at dark. Cant even hear my circulating fan running at full speed when door is closed. Just one problem... how will i light proof a...

What do you use for ventilation? I was considering to use 2x the e27 lights u got in there, for some additional lighting, but buy them in 3500k for Flower. How do they grow? And is the built-in fan noisy?

Thank u all! Might post a grow journal when i get started.

Im trying to hit as many grams/watt, so im not sure if “regular” led bulbs are efficient enough? How much do you harvest with your bulbs only?

Will all led bulbs be more efficiant than CFLs? What kelvin should i buy? Is it still same rule as CFL - 2700 for Flower and 6500 for veg?

HLG does make really good lights, I read. But the spiderfarmers edition is around 2.5umol/W, and is still in the budget end.

And then you would only do 2700kelvin, right?

Im just not that Big of a fan of the blurple light, and couldnt seem to find any white led grow light bulbs.

I can actually fit 2 in there.. didnt think i could. Might go with 2x SF600 in there, thats about 170W From qb LED.

I am about to do a 2x2x6 grow, and have bought the spiderfarmers SF1000. They say it can veg 2.5x2.5 and Flower 2x2, but from what ive read, it can barely Flower in a 2x2, so i want some supplementary lighting for the Flower period (im doing autos). What would u recommend? CFL 2700K? Led light...

Looks good man! You should be able to harvest way more and way better yield with QB. I am building a DIY grow box atm. Just wondering.. is your intake and exhaust fan placed next to each other? In that case, you should get more fresh air to your plants by dividing the two. But love your grow box! :)

Thanks, just did that. Now i just need to find out how to delete this thread, lol.

Hey Guys. I have just build a Grow Box 2x2x6 (60x60x180). I need this grow to be secret tho, so i dont have the option to use a noisy ventilator. Therefore, I’d love to hear your opinion/experience with pc fans in such “big” grow box. I was looking at the Spiderfarmer SF1000, since they produce...
