Which one do you recommend if I were to upgrade to 200x200x200 tent, fan and filter? I'm stupid at this CFM shit etc lol.
Right now in the 120x120x200 I got a 6inch fan 'ram' with the filter that comes with it, its pretty big.. but we did notice smell was leaking, i think it may be due to high humidity.. we didn't have a dehumidifier but getting one for next grow
2x 240watt leds 'kingbrite' & a SF1000 from spiderfarmer next grow , 120x120x200 but looking to upgrade probably.
So ur tent is 4.8m3 same as mine, I run a 5 inch centrifugal exhaust 350cfm and a 4 inch intake that offhand I think is 280. You lose 5% per meter of ducting and each 90degree bend, and 20% on the filter you want your tent to empty once every 2 mins I think the recommended rate is. So it's just a case of maths to work out how often it will clear your tent. Just remember you want negative pressure or you will get leaks, I just use fan controllers until I get the temp and flow right

I've gone wrong again lol, that's for 120 x240 x 200 not 120 x 120
Right let's start again, now don't quote me on this as I've always gone by eye and judgement not PROPER MATHS
A 1x1x2 would run with 4 inch filter.
A 1x2x2 a 5 inch
And a 2x2x2 a 6 inch with the highest m3 you could get or a smaller length 8 inch fan/filter there's a calculator somewhere online you can use, I'll try find it
If you want plants to thrive, you need to extract stale, hot CO2 depleted air and replace it with fresh, CO2 rich air. Better pick a fan that's up to the job. Trying to pick a fan? Here's how to size them up.
All ways found them a little more expensive, so never ordered from them.
I. Grow a tiny 2ftx2ft area and only for myself, only attitude or seedsman I goto.
it's not that hard to find a reliable store with cannabis seeds on the internet, at least it wasn't a problem for me. I managed to discover high-quality weed seeds, and I'll leave a link for you if you still haven't found anything. I've been growing weed for a while already, so I can tell you that the harvest is really good.
