Ok this is how i converted my porch into a green house.
The original porch was a pretty thick concert slab with a overhang of the roof and stud banisters and braces.
Then years ago they windowed it in but in a floor and some carpet.
It wasn't used for much then i started to grow plants there, You can see my Auto plant watering system, to see the before pictures.
This is most likely the cause of the mold and the floor rotting.
And this is where this instructable begins..........
Step 1: What You Will Need
300 lbs of mortar
200 Sanded Grout
12 jugs of grout additive
Lots of Plants
Drill Mixing Rod
**lights (i plan on making my own LED lights in another instructable)
Step 2: Step One: Removing Floor
So i had no idea what or how this floor was attached i soon learned.
i grabbed my skill saw and just cut around the walls of the floor.
There was a baseboard heater i removed because of the cost of the thing, it will be replaced by one of those eden pure electric heaters.
I will install a outlet where the wire came out.
Ok Now get your pry bar pull up a chunk out of the floor, this should reveal the 2 x 4 holding up the floor.
TIME FOR THE SLEDGE HAMMER!
I tried pulling these up the boards were glued down and nailed into the concert slab. So a whack with the hammer broke the nails right off and the boards cam loose.
I couldn't get close so i use the saws all to get a little closer to the wall. So i left a inch or two around 3 of the 4 walls.
I saved the 2 x 4 and painted them to make a footer that covered up this gap perfectly.
