Will do, I don't expect to have an issue with it backing up as there is a lot of rain here! And no issue with it backing so far but I will check as per your advice.
There is a drain (open drain hole in the ground with plastic cover) just outside the space.
My kitchen water drainage from the house goes here and have never had issues with it backing up, yet!
Do you mean do I have a floor drain inside the space? In that case, no.
I'm sorry to be an idiot here but the fan intakes air into the tent and the ducting removes the air, is that correct?
I'm looking at this fan.......?

Thanks for the links I'll look into this. I always wondered how images I saw on this site of branched out (tree like) plants we're achieved!
Now I know.
Cheers
Ah I understand, I didn't think of opening the door! Thanks for flagging that up.
No it's not legal here but the space is completely out of view from any neighbours and in a locked back yard away from sight.
Would it be possible to just leave the ducting in the open space of the cupboard, near...
