Rucks don't vibrate or atleast mine doesn't but on full pelt you know it is on so if you think it's not that loud you're obviously used to it,you also shouldn't be running a 5" cf with that fan mate.

With regards to the variac,yeah I built one the other week once I was sure what size enclosure to buy,it's a wonderful bit of kit and a piece of piss to put together,the hardest part was like I said getting the right enclosure,I oversized both the enclosure and variac.

I know I shouldn't have bought a 5"Cf but it was either a 5" phresh active cabon filter or a budget 6". the phresh filter was twice price of budget, but I had it at budget filters price, 5weeks in flower at moe will be replaced after harvest

By oversized do u mean over spec'd future proofing? As I'd like to be able to add another two aircooled lights in future but its recommended the max this fan can hanndle is 3 lights so be nice to add 2nd fan one at each end , or would I need two of varacs's

Thanks for ya help mate the enclosures are also know as project box's if u didn't know get more results if u search that

Thanks m8

As far as I am aware (JH will put us straight) you can run as many fans as you want of off the one variac so long as they don't exceed the total Amps.

I went for an oversized box because I wasn't sure how much space I would need for the Variac and I was getting it from the web.The Variac I went for a 2A so I could add more fans if needed at a later stage (future prrof) but tbh the 3A are not that much more than the 2s,the only big jump in price is when you go from 3A to 4A

Cool as I already budgeted on a speed controller from grow shop 75quid, so probably get a 4amp just incase and still save a few quid win win no buzzing and cheaper

Thanks everyone

You have the same fan as I've got weedisl and the variac is its perfect partner.They're not £50 notes from
wattbits mate,a 1A is £31.68+vat and the total cost including case,wires and connectors would only set you
back around £55-£65.


Your grow area must need ear defenders with that beast blasting out full pelt.

No ear defenders needed m8 tbh its really quiet I think u get most noise from vibration and ribbed duct.
I have it mounted on a scaff board that's suspended from celing with 5" carbon filter and ridgid pipe
to 6" fan short run ov ribbed duct to aircooledhood so little air restriction, I'd mainly need it so
it don't cool the light as much.

Angel have u built one for your fan if so how's it going?

your defeating the whole point of using a carbon filter with using a higher spec'ced fan, the air being pulled
through the CF wont be cleansed/absorbed fully by the carbon & you could end up with smell leaks.
also, theres something not right if your fan is really quiet at full pelt, whats the make & model ?

its an easy mistake to make my twin weather box is massive, when i get round to upgrading it,
i'll use something more compact

you'd have been better security wise & cost wise just buying the correct size 6" budget CF

a 2A variac will run 2 6" or 2 8" fans easy, a 3A variac will be more than enough.

Hi joint hogger pass the dutch man shit puff puff give

But on a serious note now the fan it this model rvk RVK150 L1 680 m3/h. Well I say quite I have nothing to compare it too accept youtube videos of grow rooms and thay sound like jet engines going off in there, in my room you can comfortable hold a conversation I think the noise is mainly from moving air, may sound silly but have oly 1 600w hps powerplant aircooled hood in a 9ftx7fx8ft room with 1 plant but its my first grow too everything new to me. Probably get a 4a one still as in my head I already spent 75 so peace of mind if I ever want more.

Thxz buddy

ah, the rvk RVK150 L1 680 m3/h, got one myself & when its running at 100%, it sounds like a harrier jet is in the room.



as for getting a 4a variac, its ott, go for the 3A

[Where Angels Play]

I'm pretty sure my L1 is 720m3/h.

Getting the 3A would save you £16 compared to the 4A

I think that's a diffrent fan hogger of sililar specs as the capacitor is externally mounted on mine here's a link to same one - http://www.hydrogrow...uct.asp?spc=SYF I think mine is quite tbh maybe because ov a diffrent brand?


I like going ott gives me peace ov mind but angel is right 16 quid could always go towards pots or somthing like that so I will get 3a wish I joined before I setup and when on spending spree now as I bought a maxibright contrctor relay £25 even had grow shop open up on christmas eve so I could collect my order as it killed 2 grasslin timers in 2 days lucky I was doing a week test run no plants.

Thanks for your help guys you been extremly helpfull much appreciated

... cheers JH & Co ... this thread is one of those times when the internet is such a success story. will be putting together a single 2 amp controller pronto which i got from Wattbits for 42 quid ... http://www.wattbits.com/2f-1.html ... i have tried the old "dimmer switch" job and though it worked great in my last grow with temp control an all, i did have the fan in the attic so the noise wasnt an issue ... my present grow needs stealth.

it amazes me how ignorant the hydro shopkeepers are of stealth growing and just how ineffective their overpriced digital gadgets are. they obviously aren't blessed/cursed with living in quiet peaceful locations where you can hear a mouse fart. anyhows i'll be wiring the single up to my honeywell thermostat so im guessing i wont need the relay you have in your twin. many thanks once again ... repped

Hi, what amp fuse is best in a plug for a 1amp Variac, cheers!

[bluecheese1]

think you can get 1amp fuses but if you cant use a 3amp

Brilliant. Got some 3 amps laying around.

Nice thread JH, i like your threads

What do you think of this as a cheaper alternative to the variac, it does 3A constant duty :

Hi JH, great thread, exactly what I was looking for. The maplin 0.75 VT now seems to be bigger than the one you used, so no longer fits the same project box... I have found a 1A one, and one of the gewiss boxes you linked to, and was going to post the info on this thread once it's built if that's cool, rather than starting a whole new thread?

[Groffuwiwi]

Hey Jh, great thread!

I soooo wished I had both the skills and the guts to attempt assembling one of these things.

... you think you guys are tough? Try taming a Dospel WK 200 (155w I think) 1200m3/h ... I found this thing second hand and bought it, with the idea taming the speed down for stealth. Alo bought a GSE digital thermostat and speed controller... I thought that thing was going to lift-off the ground when I first turned it on!!

Acoustic ducting works wonders! So does the digital speed controller, but living in an apartment block, the hum is quite noticeable. Guess I'm going to need a variac no matter what.

Got a couple of questions if you don't mind...

1) what are the specs I need (and don't be shy to over spec ) to look for? Amperage? Voltage?

2) Is it at all possible to integrate the two, now that I've bought the GSE and does a pretty nice job (except the humming), like connecting it in serie? Would that be dangerous? Having the digital one lower the output to the variac, and in proportion, the variac control the fan without humming?

3) why does my fan stop buzzing sometimes... like 5 minutes, 30 minutes, its kind of random and have found no correlation to the thermostat. Only when it starts buzzing do I realize how much noise a little buzzing does through the walls !! I urgently need a variac

Thanks!!
