Looking good!! Looks good and sturdy. I can definitely see Don's influence. Cant wait to see the finished product. What are your plans for summer usage?

Good job topher,I agree with josh looks nice and sturdy.I will be building something about half that tall to cover my cactus and succulent bed(and probably)extending to cover some of my palms also,everythings in now except bananas,3-4 more wks on those,I will try to get some pictures in the next week or two.I've planted about 50(20cactus,approx30 palms) palms and succulents in the last three days!

Hey Topher.looks great!
Here's a idea for keeping down and from the wind blowing it away,drill holes clean thru your base wood and drive a couple feet of rebar into the ground,oh about every 4 ft should do it it fine!
More pics as you progress a long!

Looking good so far...but be warned...it will always be too small as whatever size you make you will certainly fill it and wish it was even bigger...believe me, been there and done that!!!!

I like your design both the framing and using the concrete meshing. I really want to put one in my yard, just need to keep it out of view of the HOA commandos. Are you going to install irrigation? What are you planning to cover it with?

This weekend I visited a guys adhoc green house in the back of his business. He had over 100 species of palms growing (all rare) and a distilled water irrigation system.

I am realy confused now because i don't realy know how to keep it from getting too hot. I am probaly right now just going to put some visqueen over it and maybe some shade cloth. I only get too work on it a little i'm all by my lonesome doing it and as don says those panels are a
PAIN to get up there by yourself. But i am very happy with what ive got so far . No irrigation system probaly just drag my garden hose in and out. Don thanks for all your advise youve been a tremendous help. And i was just thinking how i was gonna tie it down . So now i know.
Will post completed pics I think i will buy a fan to run in there this summer and ive bought a thermometer to watch the heat. There is many things that i want to try once it's finally built. I actually still have some pvc from my first green house and i want to make seed holders from them. I also want to try a lipstick palm and maybe some more cocos well to be honest there's palms being discovered as we speak and I realy enjoy the rare colorful ones , maybe now i can actually keep some alive lol :) Thanks guys for all your great comments !

Topher, hi there. Having had a greenhouses in our gardens ever since a child, even here in the UK they can get extremely hot. The one we have now can get to 100f easily on a good day, and it isn't in as sunnier a position as the former one we had. Would imagine your temps would easily get way hotter than ours??
As you already realise its far easier to heat one than to cool it down. We have a door at one end and 3 opening windows, plus the roof does not actually fit down to the walls at the front or back for extra ventilation...the gaps are filled with polystyrene blocks during the winter and I also have to use shade cloth. The previous g/h was the best though as it had a door at each end plus roof windows, with this you could get a good through draught and cool the house quicker. Found that hot stagnant air can be a real drain on plants, far better to keep the air moving...so yes the fan would be a great help, esp if placed at the far end to push the hot air out rather than actually 'trying' to cool it.
Not sure what type of material you are going to cover it with permanently...my immediate thought is that yours has only the one opening, correct? Would it be practical to make part of the far end panel removeable or 'roll-uppable' as you are using visqueen at first, incase your plants start to overheat?
Just a few thoughts from a greenhouse owner of 30 odd yrs!!! Hope you don't mind me chiming in? Am sure you will spend many hours in the g/h and get to grow those lipstick/cocos palms plus lots of others! Enjoy!

Topher,
How about a mister fan,I've seen them in Magazines,that would help cool down and provide humidity at the same time this summer.

You could leave the end off till colder weather, or build your frame for a small exhaust fan. The most cost effective mist fan for cooling I have found is sold online at walmart and delivered to your local store with no shipping charges. 84 bucks, and then you can put a timer on your faucet to kick on when you want it too. Just a thought! I found a seven day digital timer at attwoods for about 25 bucks and runs on a 9 volt little square battery. Has many settings for each day.Works great and you'll never have to reset if the power goes out. Just replace battery once a year.

Here is a link that might be useful: windchaser mist fan

Iam glad we just had an atwoods open real close to home so
i'm going down there and check out some options. Thanks everyone !

Hey topher I think your plan with shade cloth makes the most sense,if you have plastic over that in summer that thing will bake (or panels)as far as a mister goes great idea but I wonder in arkansas?misters are more effective in climates with lower dew points,I've been in ark in the summer!you certainly don't need to create any heat or humidity down there!

Yeah jim i know that's the dilemma i'm having I think for now i will go with visqueen and shadecloth and watch the temps real close , But i'm gonna keep the fan in mind too.
