Fan Controllers

[wutang]

Hey guys

Do you guys own any decent fan controllers, not the dimmer type ones for about a tenner, but the ones that don't make the fan hum? I've seen a few ebay/Amazon but was wondering what you all use?

I'm trying to keep my humidity high during veg and have a oil heater inside. The extraction is a 4" rvk rhino pro in a 80x80x160cm tent with a 250w dual spec. Im hoping reducing the airflow will keep the tent warmer a bit longer rather than it being extracted rapidly, and using more energy as it tries to maintain the temps.

Cheers

Fine balance of either from what eye have been goin thru,I'm using a dehimidfryer,raising temp to 90 if my ext fan is low ,turn ip is 80 Mr. Manual control here

I got a fantronix variac speed controller, it can be turned right down and no hum it was about £60, the £10 ones made my fan hum like a bastard, now that the temp and humidity is dropping it’s coming in handy so I can turn the fan right down and can keep the heat in the tent better rather than sucking it all out.

Hey @wutang i recently purchased a turbine fan and it was loud! But I was suggested this https://www.ebay.co.uk/itm/261822147889 by a mate that has one, works wonders for me, negative pressure in both tents, and I can Turn it down at night so the Mrs can sleep hope it helps

Thanks Buddy, I have one of those and I don't find it reliable as previously I've set it at a low speed and with negative pressure, I've come back a few hours later and the fan how slower even more reducing the negative pressure.

I'm looking at something like this with no hum, its the variac one;

I will probabaly get use out of it when drying too, at least I know the speed is fixed rather than worrying about adjusting the dimmer type so precisely, can be frustrating.

I agree. I'm in the same boat..the weather has done me over this time and not having a big enough tent. If I can hold off another couple of weeks for when my tent arrives I might not need one. This tent is a 80x80x160 and it has a 1.5kw oil heater. A 4" rvk and rhino pro really suck the tent in. In my new setup Ive got a 5" rvk and rhino pro for a 1.2x1.2x2.2m tent - I doubt I'll need a controller on that, as the calculations are already close enough when the fan is running on full power. Thoughts? I wish I would have gone for a larger fan now as I now appreciate the heating/weather issue a bit more. Thanks

Way to expensive for my liking (Eli shaped hole in the wall running from that price)

I thought the same, hence in my new setup of 1.2x1.2 x2.2m I only got a 5" rvk which the calcs say is perfect for that size tent..but with heating and humidity issues I probably should have got a bigger fan ans filter with controller. Oh I don't know...so much money spent..and then theres always more money to be spent lol

[wutang]

Always money to be spent but yeah I've got a 5" ram fan running 2 tents, but I'm inside so heat hasn't been a problem for me, I'm more worried for winter as I have a cold house and no heater in my tents it's a fun game but when you get there and it clicks you'll be sorted

Ahhh, mines in the garage..the standard thermostat on the oil rad seems to be working fine, I have it set to half way. Lights on never goes about 28c and lights off never goes below 18c..seems to manage it well give or take a couple of degrees in fluctuation of temps.

What size tents do you have?

I've got a 60x60x140 running into a 80x80x180 nicked the idea from point5 1 fan 2 tents cheaper

That is a cool idea, if a 5" works for you for both tents I should be okay with it for my 1.2x1.2 cheers

I run a 5 inch RVK with an SMS controller. The only humming is at speeds so low you wouldn't use them.
If you're UK £18.50 on eBay Grimsby Hydroponics for a used one.
At the moment the fan is running a 1.2m grow tent and 60cm drying tent.
Sorry couldn't put a link up as I'm clueless how to

@wutang id say it’s a question of how much extraction you need with regards humidity and temp, I’m running led lights so temps not a problem for me on the hot side but it’s starting to become a problem on the cool side hence the heater and turning my extractor down, I watched a video and this chap in a grow shop had done co2 tests and to keep the co2 levels up the amount of extraction needed is very low indeed, so my controlling factor is humidity hence why I want a small dehumidifier so I can run with minimal extraction and keep my heat in, not quite sealed but close.
