    Optimal airflow question

    For grow rooms a lot of people say it can be even once every 5 minutes. But big rooms have more space for grow lights to dissipate heat. In small, medium grow tents heat accumulates faster so at least every minute is better to keep temperatures low. Of course intake temperature, space air...

    Oversize filter

    Would choosing 65cm (700-1000 m3h) filter instead of 40cm (436-620) for my 680 m3h fan create better airflow or create problems if i keep it on level 3/10 ( 210 m3h) ? Carbon beds depth are same. Thx

    Choosing bigger filter

    Hi, as i upgrade my exhaust equipment im going to install a bigger filter than my 150mm - 30cm long filter. As my main goal is to have quieter and more efficient filtration system im considering Prima Klima 150mm - K2602 (40cm long) / K2603 (65 cm long). Pressure drop curves for them are not...

    Stay away from vivosun!

    Their fans are manufactured in china, they are not the highest quality. Ac infinity is great if we speak about controller and their system overall but for that price they are 2-in-1. They also invested a lot in marketing and this is the real reason people praise them. HVAC/fan experts could...

    mini SOG 2x2 pot size

    Thx, after some talking with people growing in real i know it is possible. Its just matter of choosing strains/ controlling plant size with different methods. But with 9,2 liters i guess you have nice dense bush there :P

    Ac infinity fans

    Their 6 inch on higher setting is going to be much much louder than they false claim of 32db (32db is on lowest lol). The 6 inch housing is 147mm and most female connectors are gonna have a gap beetwen that. Mine two 6” whines unpleasently from level 3, its not something that havent happened to...

    Tent height and heat using same wattage

    So story comes to an end... they dont want to send me 2nd replacement as they concluded that noise is generated by adding filter. If the motor and blades were made good in first place adding resistance wouldnt amplify any frequencies in such a way. "verall the fan has 5 to 6 speeds, the highest...

    Y duct from tent exhaust to outside house and rest inside room with active intake at window?

    Im not HVAC expert but i guess you will have bigger pressure drop with this Y connection, especially if one side is longer than other. So ill suspect drop in airflow in regard how it works now (so a little less than half of your current airflow on one side of Y). With this room size and tent i...

    Tent height and heat using same wattage

    I checked first and replacement fan. They vary in specs - first is 64w/0.94a, new is 70 w/0.94a. Old rattles clearly, newer less. I read over the web that other people also noticed big differences in specs. Their S 8-steps controller have DC instead of mine VAC. Seriously wtf is wrong with them...

I prefer to smoke and smoke buddies dont last me long with lighting...

    Carbon filter for smoking

    Hi, do anyone have experience with using carbon filter in a room you smoke ? Do it helps with smell ? I once set up my used (but not 100%) filter in cardboard box that i blow smoke into. When i returned to the room the smell was still present, but less intense/concentrated than if i smoke this...

    Air purifier in drying room, good or bad?

    If its purifing air it dont do anything to your buds. Just captures evaporated terpenes and rest of shit. If the uv is working on drawn air, like dont shine outside it also wont have any effect. Certainly can keep your drying buds better protected from mold spores etc

    Tent height and heat using same wattage

    Yeah ok,i connected previous one and it rattles even more thats why it was louder humming. It can be bearings. Controller is great, EC motor can be good also. But they fcked full time assembling the blades/bearings. What a dissapointment. I spent 200$ and have two faulty fans lol. At least i...
