Green House


Years ago I got a pvc frame for a green house but didn’t get around to doing anything with it for years, here I was attaching the top cross beam.


The ends are being framed up for the doors and for a place to attach the plastic.


The doors are important, they are a bit of a pain just for the reason that they have to fit and hold up to movement. The doorway  was 48 inches so I made the door 48 inches, made the second door 47 and it worked better.


Doors obviously need to be square, providing your door way is square, reinforcement is needed.


Corners  being reinforced with plywood.


One thing I almost forgot to say, I got the frame free, don’t buy pvc, it has to be covered so the plastic doesn’t touch it or it will void the warranty on the plastic, maybe it doesn’t matter but they probably react when together.


Ends get covered first.


Easiest way to do the ends is to screw or nail the door shut so it won’t move and cover it all at once then cut out the door later with the exception of the hinge side. Prior to covering the ends or sides dig a ditch to bury part of the plastic so the plastic should be a foot longer than just to touch the ground for that purpose, otherwise wind will blow in, heat will be lost and possible the green house all together.dsc_0029

Part of the plastic buried, no reason to dig in front of the door if you want to open it.


Getting ready for the hard part, I have covered hundreds of green houses before but covering a house is never done with fewer than 5 people and I’m about to do it by myself, if a wind came (it has been windy), it could all be ruined. I also had to figure out a way to do it with out the plastic being held. If possible a person holds each corner while another person straightens the plastic and a sixth staples, but it’s just me.


Got it on, notice the extra hanging off the end, it will need to be trimmed but one of the biggest mistakes made is cutting the plastic too close and not having enough to work with, excess can always be trimmed but it has to seal.


There she is, once the top goes on you really need to seal the bottom immediately,  If a good gust of wind gets in it may cause big problems. The green house has more wrinkles than I would like but it’s not bad especially considering it was a solo job.


First plants in the green house, kale, I sprouted it under a tarp, it has been freezing almost every night. It may be too late to start it, but I’m going to try. This is the floor of the green house, it needs more work.  Ultimately I would like to bring in more soil but this is what I have now.

This house is not in the ideal spot, I have my reasons for the location but if possible it needs to be where the sun hits it first thing in the morning. It should run east to west so most of the sun hits it on the side, this one does run east to west but my house blocks the early morning sun.

People often think that a green house will make big changes, it depends on what you mean, this house is really more of a cold frame than a green house meaning that it is not heated, heating is expensive, since it is not heated it will freeze inside at night. There are options however. I have heard from people up north, that they put barrels of water on the sides of the green house, the water acts as passive solar and kept the green house above 40 degrees F. even when it was below 0 outside.

You also have to worry about massive temperature swings, ideally someone would always be there if the green house isn’t going to be automated using fans and thermostats. I will have to be very careful to pay attention to temperatures. The doors will need to be opened on most days to keep it from getting over 100 degrees during the day just to freeze at night. When I leave to work I will have to open the doors sometimes.  Then, they really should be shut at 3:00 or so to maintain heat from the day, I’ll do what I can.
