So are they quiet ? I had small garden high pro 5w and it had annoying kind of "buzzing" sound when blades spinned. Now i run secret jardin 20w oscillating on speed controller and it makes lot of random sounds. But both of them carry a lot of vibration to my tents poles and this is main noise...

I would love to see you guys mention wattage and temperatures you control with such low levels of yours fans :). I runned AC inf 6 on level 6 (~420 m3/h) in 2x4 with 300 watts to get 10f/~5c difference beetwen intake and inside temperature

AC infinity dont even mention sound measurement surroundings and distance. 32db they list as "total" noise which i dont understand is it maximum or average from all levels. Any way i tested with phone app (not precise as professional with microphone) my 6" ac inf and i get results - lvl 3 -...

How many watts do you use in that tent if i may ask ? What are your temps in and outside when you run s6 on 30-40% ?

I have thread about duct silencer types here. „Egg crate” foam is used in studios to dissipate sound - change reflected direction to many angles instead of straight bounce of a wall. But this foam dont absorb or block sound. I bought one of those growshop-hyped silencer with foam and was...

To clarify - when i mentioned two silencers will double airflow loss i was reffering to using two 30cm vs one 60cm

Depends on how much airflow it have, if its below your extractror it wont keep up with dehumidification of new air from outside

The one i bought with glasswool insulation 50cm long is much better than egg crate pattern foam one. As i researched rockwool is even better cause can muffle better low frequencies (9 db for 125 hZ instead of glasswool 7db) that are most important as they are that gets through walls etc most...

Ok so no problems with it, thanks !

Hi, if im switching from veg 18/6 to 12/12 should i only decrease last hours of light or can i change hours as i want ? For example from 6 am to 12 pm (18h) - 10 am to 10 pm (12h). Do decreasing start vs end of day have any differences ?

There is more about it on the web… i think u want 80s if your led’s dont have IR. I dont have experience with measuring leaf temperature but i saw that my mars hydro quantums with some IR heats up uncovered thermometers more than those covered. Im aiming for not more than 80 for less terpene...

Good info thx, phat seems to be classic wool inside ! Do you hear the difference in sound around carbon filter after you added one after it ? As i found out from silencer (wool insulation type) company data sheet there is no much difference in pressure loss beetwen 30 cm and 50 cm length, but...

Im considering if it will be better to have two short (30cm) silencers after and before fan or one long (60cm) on the end as carbon filter and exhaust side are located in home

Hi, do anyone have experience with duct silencer - im thinking about adding second one to my system. My current one is as AC infinity, Phresh type with egg crate pattern foam inside - i dont find to be soundproofing very much, as i know from my musical background the foam dont soundproof but...

32F is about 5c, so yeah this is temperature im going to deal with and im trying to figure out is lung room heating is necesarry or heating only tent will work. I saw one oil heater that have thermostat for room temperature but most have thermostat for just the heater

Whats the lowest temperature you have outside ur tent ? Im wondering if its possible to have 32 F outside and heat up inside

The ones from last photo is a good example of how big they can get in small pot, wow !. I saw 45 cms autos in 5liters pot on growdiaries (amnesia haze auto fastbuds that can reach more than 1 meter). Gonna try under 1 gal pots in future, im going with 2 x 6 liters in 2x2 + 1x3,8 liter that is...

Yeah, i dont think they would be good when intake air would be 32f (0c), the exhaust will need to run on very low and voila humidity problem. Although im thinking about other place to grow than OP, i think its best to heat lung room - saw oil ones with thermostat for air that controlls also...

Anyone tried tube heaters or solea ? I wonder if they can work when outside its 32F cause they use much less than 2kw oil heater...

Do you recommend blowing it underneath light upwards or above ?
