Gents.... I'm looking for some advice on throwing a filter on the intake to prevent sucking pests into the grow tent from outside (pulling in from outside as it will be cooler).

Hi guys, I got a greenhouse that is 3.1m x 1.85m x 2.5m Id say it has roughly 14 cubic meters of air, the idea is to vent the air in this greenhouse though insulated ducting out of the roof of this greenhouse, then into the roof of my house. The air will also be filtered. The location of the greenhouse is wedged in between my house with approximately 1m of awnings and a about a 2.4m fence, the top of this fence has white laser lite which will reflect some light and also let a little though. The sun passes over the house then over the fence, so the location does not get full sun all the day, but will get a few hours every day and a bit of shade - so the greenhouse wi…

Making our grow area's easier to maintain a healthy and consistant enviroment, the biggest and most recent change being in the step towards digital ballats,First just digital,then mh/hps compatable with a dimmer feature. Now Matrix (Solis-Tek) have the 600/1000w digiballas,now most digital ballasts on the market are "regular digital" solis-tek are "true or full digital" ballast,and are bringing out the new model shortly. Big deal you say ,and i did too. What …

Hi all, Ive got a tech question regarding the Growlush fans speed controller hooked to a Can fan (RS100). When using said fan speed controller and lowering the RPM of the fan, I get an electrical hum at the fans junction box which is quite noticeable. Just wondering if this is some kind of electrical feedback to the fan from the controller. Has anybody else noticed this? What type of controller do other peeps use?? Cheers
