Ok, I thought I'd post an update with some insight into the pros and cons of shed-growing for future shed-dwellers.
First, I haven't found any cons yet..! It's been a very positive experience thus far.
But there are some lessons I'd like to share.
Insulation. After weatherproofing the shed, this I've found to be one of the most important factors in achieving success. It may seem obvious me saying that, but don't skimp, it's very important. Throw as much cash as you can at it.
So, some detail ...
When I started in the reception room first, the main growroom wasn't heated ........ fuck this, room A and room B.
When I first started in A, B wasn't heated, so I used a small fan heater set to it's lowest possible setting, just to take the chill off the air. The vegging chamber had a tubular heater on constantly, so the temps in A stabilised at between 19C and 23C, the vegging chamber between 24C and 26C. Perfect.
I didn't insulate the dividing wall between the two chambers deliberately, as I wanted some ambient heat from the growroom to get through .. a little bit of energy conservation helps keep the bills down!
Now, I've found that since B was fired up, A has been getting a bit too warm .. it was at 26C in the room and 28C in the veg chamber this morning when I got there. Humidity at about 25%. Phew! baking. So, the fan heater's off tonight. Back to more temp monitoring. Flipside, B was like The Congo upon entry, my glasses partially steamed up immediately and max/min temps had held between 25C and 26C constantly, but the humidity was up to 78% ... wow. Know I understand why it's such a big problem for indoor growers .. same size plants, same size pots, same size room .. but different lights and a much more sealed environment, so nowhere for the moisture to go. Hmmm. Glad I've got a dehumidifier then, methinks.
Getting the balance right takes time, you have to constantly tweak.
I'm also getting jiggy with the ventilation too. I've had to. This is another addition to the equation ...
I've found that my plan of drawing my intake air for B from A, to be working a treat. As the air's already heated, the temp changes before and after an air-exchange to be no more than a degree or two. However, I'm only operating the fans for 2 minutes every 6 hours, I'm guessing a 6 Cu.Mtr. room has enough CO2 in it for 4 tiny plants at the moment, but I am aware that this will increase exponentially as the plants grow. Next it'll be 2 minutes every 3 hours, increasing to 2 minutes every hour, with a lesser frequency during lights-out. For the maths-inquisitive, the 6" exhaust fan (the important one) can shift 480 Cu. Mtrs an hour set to 'low', so it takes less than a minutes to suck all the air out .. 2 minutes just makes sure.
Of course, I can forget all this venting shit when I get CO2 installed. Sorry, delivered.
The pipes are already in .. he he. And it's becoming more and more of an attractive proposition daily.
Bottom line, grow's going really well so far ...
