I've been a "hobby gardener" for years. I'm getting ready to set up a family-size hydroponic garden on the back porch. I put this blog together as a handy reference. Hope you like it.
great build, thanks for sharing this. however i do have a question, most old greenhouses have clear glass, why are you not using clear plastic? i’ve seen this type of greenhouses in the shops too and they are using a non-clear plastic, why is that?
i cant believe i didnt think of this lol good job, the ladie i live with wants a greenhouse and the ones you buy at stores are so expencive and yet so poorly made, this is top notch compared to them.
where did you get the plastic from?
Good stuff! I wonder how your frame would work with some sort of plastic panelling. Perhaps you’d cut the cost of a green house kit in half if you only needed the panelling.
Check out farmtek for the wide 6mil UV covering. I am looking at making a 12′x96′ (20′ of arch) hoophouse and the twenty foot wide rolls are $2.29/ft.

I bought the larger harbor Freight Kit. It is a cheap aluminum and if you have any wind, it will fold in on it’s self. Mine got destroyed while in the process of setting it up. We had a micro burst come through and bend the entire structure over with out the Panels installed. It was just the frame. I am now considering this style. We wasted $700 on the Harbor Freight one.
Nice job on your greenhouse.Also thanks for showing in detail really helpful i also live in florida.Plan to start on mine soon.

nice job on the greenhouse. what’s a flood drain hydro phonic system?
you can do that very easily,but takes alot of work.
I’ve seen several youtube video’s on building a cheap but well done house. This is the best so far. I loved the way you did it….great shots so we can duplicate your success. Thank You, Thank You for taking the time! I can do this.
i like it. i hope that NATIONAL PIPE AND PLASTICS INC pipe
Nice video. Very detailed; loved all your narrating.
Thanks for posting.
use fiberglass.
wicked man lets live with out the system
From altha florida here

In addition, one could also utilize a passive heating method consisting of something like black steel drums, filled with water, in the interior. Black attracts and collects more of the longer wavelengths from the sun’s rays and it would heat the water during the day, while gradually releasing the stored heat into the greenhouse, at night. Just a couple of ideas. If I ever get any land, I have a lot of good ideas to put into practice. In the meantime, I work on them in my head.
@davetidwell
If I could make a recommendation in regard to the heating in the winter? I believe that this method may provide enough heat to assist in Florida, as opposed to Kansas where I live (I work on these things in my head…still working it out)? There is a composting method called the Indore method and composting through a clear plastic produces heat and CO2. If you were to utilize this method along the external periphery and vent it into the greenhouse, it may help, plus add CO2.
Tried both 4 mil and 6mil…. 4 mil lasted 6 months, and 6 mil only 3 months (maybe the heat got the 6 mil) The stuff fails on the creases from being folded… When I run out of plastic, or patience, I plan to purchase UV protected plastic… Expensive, but rated for 3 or 4 years….

Dave: What plastic did you end up using in the end? I just bought regular 6 mil plastic
With two people, and using a air powered staple gun, takes about two hours… The first time you put up the plastic it is kind of interesting, the second and third time were no fun.
NO, but could not find anything on the web wide enough.. and the uv stuff is pricey… I’m considering purchasing a greenhouse kit from Lowes or Harbour Freight. Another reader here in Tallahassee purchased the Harbour Freight greenhouse, but I never did hear what he thought about the construction..
I was using a 20″ box fan that I controlled with a timer… started the fan around noon and shutdown around 7:00P Tried evap (swamp cooler) concept, but too humid… just got everything wet.
hey genius! too hot for most plants in the greenhouse eh? ive heard of that lately online, but i thought of a way u may have thought of already, use a lil thermostat in there to keep a steady temp, either run off house power, low voltage fan and t-stat+ maybe a solar powered fan t-stat setup..
what do u think about that sir?
