Intro: Indoor Greenhouse for Seedlings
I have potted quite a few seedlings that I've collected. I enjoy growing the local trees in pots. It's much more of a challenge than growing your basic houseplant.
Sometimes they dry out, curl up, and die. More control of the humidity and temperature is required when the seedlings are starting.
This indoor greenhouse (or green pup-tent) gives newly potted plants a better chance of survival.
I have also used it to revive young plants that are struggling or in shock.
The picture shows a 3in & 4in clay pot. Adjust the frame size to fit your needs.
Step 1: What You Need
The tools required are things you already have in your tool kit. If not, hey! get with the program!
The round sticks are 12in bamboo shish-ka-bob skewers, about .15in diameter. The dollar store has a big bag for...a dollar. I find many uses for these tough little sticks. Trim to length by rolling under a utility knife (add a utility knife to picture #2). For sides longer than 12in, glue two sticks lengthwise.
The square pieces are 3/8in hardwood. You can find these at Home Depot or Lowes. A four foot length is less than two dollars. Look in the 'hobby wood' section or in the moulding bins.
A plastic drop cloth will be cut to fit the frame.
Step 2: The Frame
Drill two holes in the ends of each piece. The ends will be mirror image. Use a brad-point bit if you have one. I used 5/32in.
Attach a small c-clamp as shown to keep the wood from splitting. A vise with smooth jaws would work fine, too.
Make the through holes a little small, then sand the skewer ends for a tight slip fit.

I didn't use any glue because I want to break the frame down when it's not being used.
Step 3: Plastic Wrap
Cut the plastic sheet about an inch wider than the frame and a little long. Start by taping one end to the bottom piece. Three small pieces of tape are much easier to control than one long piece. Drape the plastic over to the opposite bottom piece and trim to length with scissors. Pull it just tight enough to get rid of the wrinkles, center, and tape.
Do the same for the adjacent side.
Close up the loose flaps by folding down and taping. Again, use small pieces of tape. Done.
This is the third one I've built, all different sizes.
If you decide to make one, the techniques I used may save you some of the frustrations of my first build.
Ladies and Gentlemen, start your seedlings.
