Urban Greenhouse

Welcome to my Urban Greenhouse Tutorial! When I was asked to do this project I was pretty excited. Not only do I have the perfect rooftop for such a project, but I’ve been in the mood to incorporate more plants into my already pretty Zen lifestyle. Here, I’m going to tell you step by step how I created this look and also lay it out to where you can easily do the same… or do something completely unique, it’s completely up to you what you take from it. My only hope is that it inspires you to create and share.

Like most of my projects, I started with a sketch and quickly learned I needed to make some measurement adjustments, such as the width after adding the PolyCarb panel to it, but this gives you a rough idea of what I was going for…

Materials and Tools I used:
‣ 1 Broken down pallet, along with whatever scrap wood I had on hand
‣ 8ft Tuftex PolyCarb panel- Cost roughly $25
‣ 2 4ft Wooden Closure Strips
‣ 1 Box 2 inch Neoprene Washer Screws
‣ 1 8 ft strip 2 inch flashing
‣ Drill
‣ Tin Snips
‣ Nail Gun (with compressor)
‣ 1 1/2-2 inch brad nails
‣ Drill bit 2/16- 3/16 larger than the Neoprene Washer Screws
‣ Mending Plates (though I Highly recommend using a Kreg Jig instead, if available) ‣3/4 Hex Bit
‣ Pencil/Marker
‣ Jig Saw
‣ Tape Measure
‣ Miter Saw
‣Table Saw
‣ Hinges for lid
‣ Spare Paint- Keep it Light
‣White Spray Paint
‣ 4 Self-Drilling Screws

I started off by purchasing my 8×4 piece of Tuftex PolyCarb at my nearest Lowes, along with the Neoprene Washer screws that are needed for the panel, and the two Wooden Closure Strips. You can find all three together in the same section, so you wont need to run all around the store looking for each piece~ Thanks Lowes! For greenhouses, the Tuftex website recommends the Polycarb Panel, and warns against using the other panels they provide, such as Seacoaster, which is Not meant for greenhouses. So be sure to grab the correct one before spending your hard earned money..

My greenhouse needed to be roughly 3 feet long for my space, and the Tuftex panel is 26” wide, so I cut it into Two 26” long pieces using my Tin Snips. The panel can also be cut using a Utility Knife or a Circular Saw with a plywood blade set in reverse. Note: I used my Tin Snips, but if you have any wrist issues, you might want to use the Circular Saw instead. Once my panels were cut, I overlapped them by One Corrugation (Which is the minimum and maximum for overlap) to get my final measurements for the lid, which came out to 49.5” wide and 26” high.

Making the Lid Frame~

For the lid frame and base of the greenhouse I was using scrap pieces of wood I had in my garage, because of this, I ended up using some 1×2’s that were long enough to work. I cut down Two pieces at 26” for the sides, and Two more at 49.5” for the top and bottom, adding One support for the center at 24”. I used wood glue, brad nails and mending plates on each corner and center. Looking back, I should’ve used my perfectly wonderful Kreg Jig I had sitting right there.. Lesson learned for the next one. A Kreg jig will definitely create a stronger joint than the mending plates brad nails, but it still did the trick and it’s just for my rooftop. So if you don’t even have a Kreg Jig and want to be crafty with what you have, this is for you!… I’m o.k with my choice, yep, I’m totally fine with it… Ahem, moving on..

Closure Strips and Flashing~

For the closure strips, they only need to placed on the top and bottom, and Not the sides.
Based on the size of greenhouse you’re making, you can purchase as many anclosure strips as you need, and either cut them down at the hardware store, or wait till you get home. Tuftex also provides Foam Closure Strips, but to avoid over drilling and cracking my panel, I went with the wooden ones they offer. They’re slightly more expensive, but it sure beats having to go buy another panel if you accidentally over screw. The strips need to be light in color to avoid overheating with the panel, so I spray painted them white, and ended up brushing on some white on the lid frame as well… Sadly I thought of that After it was already put together~ To save some time, it’s probably best if you just go ahead a spray your lid frame at the same time as your closure strips, you’ll thank me later. With the closure strips ready, I used my Tin Snips to cut down my Flashing to match the width. Flashing only needs to be placed on the ridge, so I only used 49.5”

Putting It All Together~

Note: Screws should only be installed on the crowns of the corrugations, Not in the valleys

I lined everything up on the lid frame, with the two closure strips at the top and bottom, and two panels overlapping by the one corrugation required. Then, using my drill bit (Make sure the one you use is 2/16-3/16 larger than the screws you’re using, I’m telling ya, the last thing you want is to get this far and then crack your panel when you’re finally putting it together) I predrilled every other corrugation, which needs to be done to avoid wind uplift. Once my holes were predrilled, I used my Neoprene Washer Screws and secured them using my 3/4 Hex Bit, and as mentioned before, was extra careful not to over screw.

(Again, I’m trying to save you money and more trips to the store, you’re welcome 🙂

Building the Base~

Note: I have an abundance of 2×4’s from old pallets, but if that’s not your case, you’ll need to buy a couple 2×4’s and whatever wood you’d like (fencing boards work nice and are relatively cheap)

Cuts~
2 2×4‘s to 38” and 2 2×4‘s to 42” The top of the lid should be at least 4 inches higher than the bottom, to give it the angle it needs 6 Front and Back Boards to 49.5” Bottom shelf (multiple at 20”) Support boards ~Two strips at 45”, Two pallet boards at 24” and Two support boards for the floor at 20”) Floor board for the plants to sit on (44×20”)~ For this I used my table saw and cut one large piece from scrap Sides ~Four pallet boards at 24” and Two pallet boards cut at a 20 degree angle for the top)~ I used my Jig Saw for this, which I don’t think I mentioned in the video, my bad.

Installation~

I started off by securing my two precut 2×2 strips at the front and back. Inserted a 20” support board at each end to place my 44×20” board onto. Then secured everything into place using my 1 1/2 inch brad nails. The side pieces were then nailed into place starting at the top with the precut angled pieces, and working my way down, to make sure the top would be squared with the lid. Next I measured how high I wanted my shelf to be and attached the two 24” side support boards and placed 2 2×4’s on top of them running perpendicular. I nailed all my precut 20” shelf boards to the 2×4’s using my 1 1/2 inch brad nails.

With the base done, I set my lid on top, and made any needed adjustments before attaching the back hinges and adding the precut flashing. There are several sizes of flashing, and since I was using frame strips that were only 1 inch thick, and Closure strips that were also 1”, I chose a 2” flashing that would allow my hinges to give me the opening allowance I needed for the id. I attached the flashingonly to the top ridge (to stop rain water) by using 4 self- drilling screws.

Prettying up your greenhouse~

With so much spare paint in my garage, and so many colors, it was hard to chose which one I wanted. Since I was using the PolyCarb panel, I knew it had to be something light, so I picked one of my light teal colors that I love so much and haphazardly brushed it on. I like the rustic worn look, so I didn’t want to cover too liberally, and instead wanted to leave it looking like it’s been sitting in the sun for a while.

That’s it! I was finally ready for my herbs and I had my own little greenhouse I could enjoy for seasons to come.. Complete with a shelf for storing my potting soil and nick nacs!…. I hope it somehow inspires you to grow something, build something, or just create something. Either way, Thanks for stopping by!

Alright, so here it goes….

I’m finally doing it. Starting a blog, creating a website, getting my shit done. Its a fun and scary leap. A leap that puts me out there and subjects me to outside opinion and advice that I may or may not want or need, and I gotta say, Im pretty damn excited!

A little about me. I’m 38, never married, never a mother (except to a few adorable animals) and the youngest sister of three.. well four, counting my half sister which for some reason I always forget to do. I’ve traveled, cried, and laughed a lot throughout my life. My passions are and have always been centered around anything creative… music, arts, building, learning, reading, traveling, etc. I have horrible handwriting and just as equally horrible grammar and spelling, which I’ve always used (truth be told) as an excuse not to do a blog, or write, or create a best selling novel, but here it goes. No more excuses, it’s 2016 and I’m tired of putting my life on hold to make my insecurities satisfied. I am a builder. I am a Designer. I am putting myself out there and that’s all there is to it!

Now that being said (probably better off to a therapist than to the internet) I’m so excited to share some of my designs and creations with you. If you stick around long enough, you might see something you like, or something that gives you an idea to try and perhaps make better. Maybe you’ll even share some of your secrets and let me have a go at ’em. I mean, if we can’t create and share, what are we here for? I hope this blog grows into something good.. Here’s hopin.

What you’ll see on this blog: Misspelled words, Before and After photos of various projects along with how I did them, run-on sentences, a lot of ()’s, commas where they probably shouldn’t be (I love the commas), New designs, and videos when I’m able to do them or my iMovie doesn’t kick me out. If you have comments please be nice, good energy is appreciated.

And we’re off!
