Small Greenhouse: Make It Step-By-Step!

If you’re thinking about starting a small garden but don’t know where to start, you’re not alone. Many people are intimidated by gardening and don’t know where to start. In this blog article, we will give you tips on how to make a small greenhouse. We will walk the entire process step-by-step, from planning to building to planting.

What You’ll Need

If you are using an existing structure like a shed, check with your local building codes to ensure it is safe to cut into the roof. If it isn’t, build a temporary frame out of 2x4s and plywood to have something stable to work on. Cut down the 10 x 12-inch plywood to size and place it on the ground inside the frame. Make sure there is enough space around the plywood’s perimeter for when you paint it.

Use the 1/2-inch PVC pipe to create vents in each plywood corner. You could just leave them off if you don’t want ventilation. Next, drill holes at each end of the PVC pipe so that it fits snugly into each vent. Stick one end of the PVC pipe into each hole and tighten it up with a wrench. You’re ready to attach your green wall!

Now that your green wall is assembled, it’s time to paint it. You can use any paint or sealant that is safe for wood but be sure to wear gloves and avoid getting any on your skin. Once the paint or glue is dry, use a straight edge and a ruler to line up the cuts you made in the plywood with the vents.

Then use a circular saw or hand saw to cut out the holes. Leave enough space around each hole to screw in your PVC pipe. Finally, use a Stapler or Hammer and Nail Gun to attach the PVC pipe to the plywood.

To make a small greenhouse, you will need the following supplies:

– A 10 x 12-inch piece of plywood;

– A piece of 1/2 inch PVC pipe (about 24 inches long);

– A 1-inch hole saw;

– 1-inch galvanized finish nails;

– Tape measure;

– Ruler or a straight edge;

– Circular saw, or hand saw;

– Paint or a sealant to protect the wood;

– Scissors;

– Stapler or a Hammer and Nail Gun.

How to Build a Small Greenhouse

Making a small greenhouse is an easy way to extend the growing season and protect plants from extreme weather conditions. There are several DIY methods for building your greenhouse, but the most common is to use a tarp or sheet of plastic as a roof and walls.

Choose the correct type of plant to make the most of your small greenhouse. Many tropical plants can survive in cooler climates, while cold-hardy plants will do better in warmer environments. Once you’ve selected your plants, build the greenhouse around them using cardboard, wood stakes, and ropes. Make sure to overlap the stakes by at least two inches to keep moisture in and pests out.

To maintain your small greenhouse, clean it once a month using a garden hose with some Dawn dish soap. If there are any significant problems with pests or fungus, call a professional to take care of them.

Tips for Keeping Your Greenhouse Healthy

You can do a few things to keep your greenhouse healthy and productive. The first thing is to make sure that there is good sunlight penetration into the greenhouse. One way to do this is to put a skylight on the roof or use shading materials on the sides of the structure. If you have windows on the side, be sure they are wide open during daylight hours so sunlight can get in.

Another critical factor in keeping a greenhouse healthy is maintaining an even temperature. To do this, ensure no drafts coming through the glass doors or cracks around them. You can also install window Film Heat Reflectors which help keep your greenhouse’s inside at a consistent temperature all year long!

Watering is also essential for keeping greenhouses healthy. Ensure you water your plants only when necessary, and avoid over-watering as this can cause root rot and other problems. Use a moisture meter to check how much water your plants need, and give them just enough water so that their leaves are slightly damp but not soggy.
