Hey guys quick question I have a 39*39*79in grow tent. Can I use a inline duct fan for exhaust or do I need a high velocity fan?
Off topic but I have a question about my light. Yesterday the light ran fine today I turned it on and only the little bulb in the middle lit up. I left it for hours came back and still just the middle part it's the mh conversion bulb both ballast and bulb are less then a month old.
Likey faulty bulb. Some hydro shops will have used equipments for sale. This could save you a bundle on a fan.
To save coin? Sure why not. I bought mine used for a fraction. Best of all we tried it before I bought. So I could hear if the bearings/motor made noise or got hot. They are pretty basic and not much to fail on them.
