How to Make a DIY Greenhouse _ I Like To Make Stuff

Hey , I'm Bobby and I like to make stuff today .

We're gonna make a greenhouse today .

We're at Josh's house on the side of his house .

He has a really large open space and his wife has always wanted a greenhouse .

So we're going to build one to go here .

This is going to be a lean to style greenhouse .

It's not going to be attached to their main house .

It's not going to be embedded in the ground and there's a bunch of different ways to make greenhouses .

This is just one of them .

Now , the first tip here is to clean off this wall because this is all going to be covered up by the back wall of the greenhouse .

We're going to do that now to give you an idea of how big this is going to be .

It's going to be six ft off the wall and 12 ft long .

Each one of these sections in the concrete is three ft .

So we're going to have four of those 1234 and it's going to end right here .

Now , the door to the greenhouse is going to be right on this end .

So you can walk around from the back door and walk right inside .

We've got a whole stack of two by fours here that we're going to use for the entire construction and we're going to start by making the floor .

The floor jots are going to be two by fours , 16 inches apart , 16 on center and the entire thing is going to be 12 by six .

If you wanted to scale this down by four ft , that would be super easy to do .

You can make it eight ft or four ft or whatever you want for this .

I'm going to use a pneumatic framing nailer and a lot of times people confuse this with the roofing nailer because it's got a coil .

There's actually a coiled and a straight version of both roofing and framing nailers .

I'll have this linked down below as well as all the other stuff we got at Lowe's in case you want to check it out so far , I've only put in this one and one down there .

These are four ft from the outside edges .

Now , I said earlier that we are going to put all these pieces 16 inches on center and we're not actually going to do that .

16 is the minimum spacing to make sure that the floor is fully supported instead of 16 inches , we're going to break each one of these areas down into three equal segments and then just put the two by fours there .

We've got the frame laid in place and this is not its final position .

It's actually going to be closer to the wall , but we have to be able to work on the back of it before we push it up against the house .

And also we can't level the ground underneath it without completely grading this area , which we don't want to do until we get it into its final position .

We'll deal with that later on .

But for right now , I'm going to start building out the back face of this and nailing the pieces in place so that we can get the back complete , move the whole thing into place before we do the rest of it .

I've got the vertical pieces up on the back and they're really floppy right now because they're only connected at one little spot on the bottom , but we're about to tie them all together with 12 by four going all the way across , then we'll have at least kind of a stable wall .

Now , at this point , there's nothing to stop it from going forward and backward .

So we're also going to build the front wall and then connect to the front to the back at the top corners and that will at least give us a stable structure for today .

We thought this area of ground was pretty level .

But once we got the frame pushed into place , we saw that it wasn't going to be good .

So we decided to stop work and figure out a way to get the surface level all the way across .

Now , like I mentioned before , you could grade the surface ahead of time , but we didn't really want to do that .

So instead , we used some two by fours to act as feet going all the way from the frame to the ground .

We used two levels on the frame and worked our way from one end to the other , making sure that the entire thing was level and now we've got a great surface to build on .

We got this outer frame put on , but I'm not going to nail these two pieces in yet .

I'm going to screw them in instead because eventually we want to take them out so that we can lay down the floor panels on the floor Joyce .

Now we're ready to lay down the floor and this is going to be two layers .

The first is half inch pressure treated plywood .

We've notched it around the two by fours .

We've laid it down and we're going to use decking screws to hold it down .

Then on top of that , we're going to use some outdoor siding .

This is a composite , it can get wet , it will be just fine and it actually is going to look a lot better on the floor than just regular plywood .

We got the floor put down and we're going to finish putting the uprights on the sides just to make sure that this is parallel with this .

We've got some spaces on the top and the bottom .

We can just slide it all the way over and nail it in place .

The framing is now complete .

We got the floor down and now we're going to start wrapping the outside of this with some paneling .

We took the off cuts from these floor pieces .

These are going to get nailed onto the walls right here and then wrapped in some trim just to make them look better .

Now , the clear part of the greenhouse is going to go on top of these pieces , but we'll get to that in a little bit to cover the outside of the greenhouse .

We ordered these four by eight sheets of plastic and we couldn't get them at our local store .

Unfortunately .

But luckily if you order from lowe's dot com , you can have them delivered to your local store for free , then you just gotta go pick them up .

This plastic actually comes with a white sheet on the outside that you could leave on if you really wanted it to not be fully clear .

Some people actually paint the inside of greenhouses white to cut down the amount of heat , but it's up to you whether you leave this on or take it off and have these pieces completely clear .

And I think in this case , we're going to pull this off .

This is basically the same stuff that you would find on a political sign , it's two pieces of plastic with a corrugation on the inside .

And so since it's thin plastic , you can easily cut this with a utility knife .

So we're going to set it down into the trough that we've made down here , cut it off at the top and then connect the panels .

I said I was going to use a utility knife and that would make more sense if you were cutting this way in between the corrugations , but we actually have to cut across them .

So instead I'll use a circular saw .

We've got these roofing screws that we're going to use to put this stuff on .

It has a washer and a gasket and really in this case , that's really just going to help not crush the plastic as we screw these in Bob's in the garage , cutting up the rest of the pieces for the roof .

I have to worry about the door .

It doesn't need to be really heavy .

We're going to use some of the same plastic for the top and some of the same trim for the bottom .

And so I'm going to frame this out nice and simple using pocket holes and three quarter inch material because again , it doesn't need to hold a lot of weight .

I've got the door made up , it fits the space just fine .

And before I add the plastic , I'm going to attach it to the greenhouse with the spring hinges so that when you let go of the door , it just closes .

We still have to add a little bit of trim to the outside and maybe some bracing .

So it doesn't sag .

But while I work on this , Bob is up working on the roof , I've got the center panel on roof and I put this on the same way that we did the stuff on the outside .

It's got a channel on each side so we can slide on two more pieces .

But we also have to cut some holes in this .

Oddly enough , we need to add some vents to make sure that it doesn't get too hot on the inside .

We can open these vents and let some air out .

So I'm going to get a jigsaw up here and cut a hole to make the flaps on the top of the roof .

I cut down a few more pieces of this and then I also cut down one piece that's a little bit smaller .

This is going to act as my template so I can lay this on the roof , trace this shape and then cut it out and I'll be sure that the flap is going to cover it enough on each side .

Then I'm going to put the flaps in place with some flex tape .

We chose flex tape for this because it's a waterproof tape .

It's used often to seal up leaks or things like that .

Water is not going to mess up the adhesive and in this case , that will work out really well because it's going to act as a hinge exposed to the elements exposed to rain and the humidity on the inside of the greenhouse .

If you make a greenhouse like this , I do have one recommendation .

Don't do it in the summer time because it's insanely hot on the inside .

I've got to put a few more screws down here to attach this last panel and then we're going to run a circular saw down the front edge to get a nice clean cut on all of these panels .

I also wanted to point out one thing in this particular case , we're going to run some lag screws through the back of the frame into the house to make sure this thing stays down .

But if you live in an area where you have to deal with high winds , maybe hurricanes , you want to look at how you're supposed to strap something like this down .

So it stays in place in those situations .

Just be sure to check your local code .

I got both vents put in on the top and Josh cuts some little pieces of wood that can be clipped into place to keep them open .

And when you're ready to close them , you just pull those pieces out and they'll fall down .

Now that will give us air out .

But we also need a way to get air in .

And for that , we're going to use these registers .

These are ac registers , these are specifically made for high humidity areas and they can be open and closed so we can cut some holes right down here .

Put a register here and one on the other side and then this thing will be done .

So here it is the final greenhouse .

Now , there's a bunch of different ways you could do this .

There are tons of different designs for greenhouses .

This one was made specifically to go up against the house .

In fact , because it's up against the house , we ended up not even putting a back wall on it because it just uses the house and it's holding plenty of heat on the inside .

We chose the plastic for this , but honestly , the stuff is pretty expensive and there's a bunch of different options that you could use to cover a greenhouse of any type .

You could use this stuff or you could use the white version of it , which is a lot cheaper and will actually create a little bit of shade .

You can take plastic sheeting on a big roll and wrap each one of these sections .

It's going to be a lot cheaper but not as strong .

The construction for the greenhouse is pretty much universal , but depending on where you live and what the temperatures are like , you may need more vents or fewer vents .

You may need a fan , you may need a heater .

There's a bunch of different options that will all depend on where you live .

Huge .

Thanks to Lowe's for sponsoring this video .

We got everything that we use in this project tools and materials either on Lowe's dot com or at our local Lowe's store .

We'll have links down in the description for everything so you can go check it out .

We've got tons of other types of project videos for you and if you're not subscribed , be sure to do that as well .

That's it for this one .

Thanks for watching .

See you next time we've got a whole pile of two by fours here and I'm gonna attach it now with some spring hinges so that whenever the door fart , I think it's fine for what we're planning on farts .

But if you live in an area with high winds , maybe if you have .
