Hi all, I'm in the south of the uk, and I'm about to do my first grow. I've built a shed (6ftx4ft) in my garden and have ran electric's (properly) too it, the UK is currently at 22'c. I have boarded a box room in the shed (3/4's of the shed) and am running a 400w HPS and have a 4 inch carbon filter with exhaust fan and a 4" air intake and a 4" desk fan for inside. I've been doing a test run before germinating, and it's hitting an often 95'f but anything between 91-100'f. I've set the timer to 1600-1000 UK time for the 18/6 veg light cycle. I would say my room is 4ftx4ft and a metre high. The air intake us from the air inside the shed, so am wondering if that's the problem. Any advice from the room would be great!! The seeds I have are Barney's Farm LSD and some freebie auto emerald jack,
intake air from under shed floor asuming it's off the ground run your dark cycle during hottest part of the day add a couple more circluation fans i use a 16" and a 6 " in a 4by 4 by 6 tent in my garage and have my light cycle from 22:00h to 10:00h
Unfortunately the shed is not rasied, so am thinking tuning the air intake from straight outside? Just worried about the bugs. Etc. Are you running 12/12 for veg or are you budding?
I would suggest getting your intake from the outside FRESH air. Then, I would suggest maybe getting a little bigger than a 4" desk fan. I have about the same size grow and use a 10" oscillator fan, and a 4" desk fan. Lastly, is there a reason you dont have an exhaust? Intake at the bottom, Exhaust at the top.
Looks like I need a re jig on the intake then! Have exhaust 4" out take sucking air through the filter first before going through duct in the shed. Plus it's been 3 days since I germ'd some seeds and put into pots in a propagator. Still nothing Cheers for the tips so far!
