Building a green house

[209 Cali closet grower]

Well it's start to warm up in California. So thinking of building a green house, to hold, like 24 plants, or less if bigger. Thinking of using strong pipes, like sch 80? And the clear plastic u get at Lowe's. Any inoffensive would be great

I used the heavy 6 mil plastic from Lowes, works okay. build your green house taller than you thing you need... my girls hit almost 14'

Don't use the cheap 6 mil wrap if you want more than 6 months of use out of it. You need a skin that is UV protected or it will literally break apart into tiny little pieces from sun exposure. Get something from a greenhouse supplier that is designed for outdoor use.

Out in Colorado the lowes/home depot plastic cracks and breaks due to the sun every 2-3 months and needs to be replaced. That's also at 9k+ feet elevation though, so the u.v rays are stronger here. I'm going with u.v resistant, anti condensating plastic this year. Pain in the ass replacing the plastic 4-5 Times throughout the year.
Good luck!

I agree. I built a greenhouse last winter for veggie starts and used the 6 mil plastic. Didnt1even last til the end of the year. Now I'm redoing it with free windows i got on craigslist. Finished it up yesterday.

Nice! My gh has lots of free windows salvaged from the roadside. Love repurposing stuff!

Make sure you leave plenty of side, front and back openings for air circulation.
I have 8x8 doors front and back, 5 foot roll up sides, two interior circulation fans, a 4X8 screened opening above the front doors, and a 4 foot exhaust fan above the back doors!

Schedule 80 ? Think about that

i havent done an outdoor greenhouse in years... back in the day i would install microsprays and mist nozzles on the top ream pipe powered by a pond water pump... i dont know what i was thinking at the time, but that moisture caused some molding and mildew. so if by chance you thought of it, just keep that problem in mind....

Used windows are a good idea. I have a couple of friends who do home improvement kind of work. I get used windows from them all the time. Just frame out your greenhouse to fit your windows, and put poly carb panels on top.

Spend 40-60$ on some Greenhouse film I got mine from Amazon it's rated for 6 years and lets a good amount of light threw. I've used cheep plastic from lowes for a few years and I would Not recommend it at all, it last for maybe a year and IMO diffuses the light too much. I mean if you're just trowing up something for a season and on a budget go cheap plastic.

Make sure you buy pressure treat lumber start thing about buying a fan for venation.

Might I recommend using something like this

as opposed to the plastic wrap?

I used to have a greenhouse in SoCal, built myself a hoop out of PVC and that worked just fine. The visqueen totally sucked though, couldn't keep temps below 90 to save my life because it seemed to absorb the sunlight (explains why it craps out on you eventually), trapped humidity inside, and caused way more problems than it was worth.

The windscreen I linked to you goes for about the same price, cheaper even at some places. Light penetrates through it much better than the visqueen, plus you get airflow from all the little holes in the screen. When I remade my greenhouse with the screen I noticed better results by the next day. I don't even think I had the visqueen up for a week before I tore it down and replaced it with the screening.

I got a bunch of windows laying around.

There is an old greenhouse at my Mamma's old house. It had a fiberglass roof, three big windows, with plastic wrapped around the rest. A good thing about the windows is you can open them to get some airflow. Just put up screen or chicken wire to keep varmints out.
