OK, so I looked through the already existing threads here and hoping can get some feedback on drying firewood in a greenhouse. I have a 6m (approx 19 feet) by 3m (approx 10 feet) greenhouse (see attached picture). It's just a standard cheap ebay kit. I put black plastic down on the ground and then blue tarp over this to reduce amount of moisture entering the greenhouse. Both sides have pallets running down them. I stacked the wood in rows of 3 (show in pictures). I stacked both sides about a metre high with dripping wet wood (stringybark). I didn't measure the MC but it was cut fresh. I kept the greenhouse completely closed (windows on both side shut). At first I did not have ventilation (whirlybird) on the top. After a while and reading here I put in a whirlybird to reduce condensation that was forming in the early mornings of winter and try to replace the air to improve drying times. So, after probably 8 months in the greenhouse the MC of the wood is down to around 15%. Based on what I've read here, that's rather poor. Seems people are getting under 10% MC in less than 6 months.
So, my questions. First, should I change how the wood is stacked. The way it is I doubt the middle row and wood towards the bottom is getting any or getting limited air circulation. However, from pictures I've seen here people don't seem to be leaving much space between rows, or it's possible I can't see clearly in the pictures. Second, ventilation. I am thinking to either put a 12v fan under the whirlybird and have it connected directly to a solar panel via buck converter. This way it will only come on when there's enough sun providing power. Should I also open the windows on the sides? Doing this however will obviously reduce the heat in the greenhouse but it will improve ventilation.
I'm OK with the setup but think I should be getting better results. Do I need to change how I stack the wood or does it not matter and I need to improve ventilation? Windows open with fan under whirlybird or fan on either end, one sucking and one blowing. I'm in Tasmania, Australia. Our winters are warm compared to what people here experience. Winter ranges 3 - 11 degree Celsius (37 - 51) and summer 17 - 23 (62 - 73). Appreciate any feedback. Thanks.
