Part four, CO2 delivery.
Now, as you all already know, CO2 is heavier than air, so it needs to be delivered from above the plants for maximum efficiency.
I've been pondering a simple cheap solution ... and the idea hit me when I was checking the electrical conduit I installed for the electrics to the shed a few months back.
Plastic electrical conduit.
Water-tight, so logically gas-tight too, and cheap as chips (fries), plus easy to install and drill holes in:

I'm using the slope of the roof to my advantage, by installing the tubes so that the delivery flows downwards, requiring less pressure to push it through the tubes.
The ends were soaked in boiling water for 10 minutes and clamped with G-clamps. Not a total seal, but I'll come onto that in a minute.
What's wrong with the above picture?
Well spotted. The holes are pointing downwards, and as everyone knows a compressed gas released at atmospheric pressure gets very cold.
Pushing it down a narrow tube full of air into a warm environment is only going to create condensation in the tube and with holes pointing downwards, the condensed water will drip from these onto the plants and we don't want that.
Simple solution, turn the pipes 90 degrees and drill some more holes in the other side. Let the gas come out of the sides of the tube and with the crimped ends now vertical, any water excess in the pipe will drip out of these instead.
I wanted to keep the gas bottle outside the growroom, next to the shed door for convenience:

Much easier to change and I couldn't have got one through the growroom door anyway!
All theory, so we'll see if it works soon enough.
Next up, part five, the fucking electrics! Zzzzzapppp.

This is where I'm up to as of today, so you may have to wait a few weeks for the next instalment.
Thanks for the compliments @derek420colorado .. very much appreciated.
I've got heating and air circulation already covered ... I have an excellent piece of kit I've been using in my greenhouse this summer and it's the dog's nuts. Planning on using it indoors in the shed over winter:

I've had it on the 1Kw setting (it goes up to 2.8!) and it hasn't even kicked up a sweat yet. Air circulation is very impressive, it's designed for orchids and such like where temp variations in the orangerie are critical. Highly recommended.
My super skunks in the greenhouse are totally bud-rot free. He said, smugly ..!!
Happy Bud
You may want to check whether or not the plastic used to make the conduit might be reactive to CO2 . Some gases can be corrosive with some materials. Always good to check when using saomething for a purpose its not designed for, just to be safe.
Oh, by the way, I do take all your comments seriously ... I can't think of everything, that's why I'm posting it all up here in the hope that some peeps more clever than I will point out the weaknesses.
Off to bed to dream about LEDs now!
