Introduction: Easy Greenhouse (Cold Box)
A cold box is used to start seeds and to help force seeds to germinate before they are in season.
Step 1: Step One: Materials List
You start with 5-3/4"x10' Schedule 40 PVC pipe, 8-3/4" elbows with a 1/2" to 3/4" screw in slot, 8-1/2" to 3/4" connections, 1- roll of 3.5mil clear plastic sheeting and 1 roll of duct tape.
Step 2: Step Two: Materials Close-up
Elbow connections and screw in connections
Step 3: Step Three: Materials Close-up
Plastic Sheeting and Duct Tape
Step 4: Step Four: Needed Tools
All you need for tools is a hack saw, measuring tape, Sharpie and a razor knife.
Step 5: Step Five: Cutting and Assembly
So you cut your PVC pipe into 5' sections. The take 2-5' sections and and cut them into 4-2.5' sections. Then you take the corner connections and put them together.
Step 6: Step Six: Assembly of Top and Bottom Sections
Before you know it you have two boxes. Or your top and bottom pieces.
Step 7: Step Seven: Adding the Corner Connections
Then you screw the 1/2" to 3/4" connections in to their corner locations.
Step 8: Step Eight: Adding the Uprights
Then with the remaining 5' sections you place them into the corner pieces on both the top and bottom sections. Essentially, you are build a big cube.
Step 9: Step Nine: Adding Plastic Sheeting and Shelves
Wrap it in the plastic sheeting and tape you edges with duct tape. I had an extra piece of pipe and end caps that I filled with sand to hold the front flap down. And for shelves I used some metal shelves I had left from a previous indoor project. Clamps will hold the flap in place and keep the wind out.
We have a be nice policy.
