 Work in Progress: Homemade Portable Greenhouse  1

This is my 4X4X6ft greenhouse. I've still got a little work to do but its almost done and seems to be functioning decently. The frame is made of 3/4 in PVC, and the cover is plastic sheeting you can get from the painting section of your local hardware store. I used an iron to weld the sheets together and make a seal. You just layer two sheets of plastic and then put a piece of paper over them and iron the paper. I had to patch a few places with additional sheeting that i accidentally melted with the iron.
For an entrance I got a tarp zipper that tapes to the side, then you cut through it to make your opening.
I've still got to cut holes for air exchange. I'm using a downstream inline fan. I'm going to attach the humidifier hose to feed in moisture through one of the gabled panels. Then I'll seal a tarp to the bottom to waterproof it and put in shelving.

That's rad. Also give aluminum foil a try instead of paper for the barrier between iron and material. It's more forgiving from my experience.

First get the space heater out of there. Besides the fire hazard, it'll rust and get filthy fast. If it's needed put it in the room, not in the chamber.
What are you doing for shelves? They will also rust and get filthy pretty quick.
A tarp for the floor sounds less than ideal.
If you're putting shelves in there and walking inside, a tarp will rip.
A tarp laying directly on the tile will cause condensation (and then mold) between the tarp and floor.
For the same reason, I'd recomend pulling the whole thing away from the wall at least a few inches, air circulation is your friend.

I glanced briefly and thought that was his humidifier. Yeah, no heater in there.

Most successful american mushroom farms fruiting rooms have rusty nasty shelves and cobwebs and substrates that need to be tossed. Not that you should model after that but some rust ain't going to hurt shit. But bamboo racks and trays are pretty cheap and do well in shower environments. I wonder how they do in perpetually wet condition.

ALright, noted. will remove the heater and place it elsewhere. Will consider not using the tarp for those reasons. However I'm currently getting some water draining into the greater room.
I spent roughly $27 on the PVC and connectors, and sheeting ran about $17

That plastic sheeting with the reinforced floss-like material may help if you find that stuff tearing on you. Looks good though.
