You can easily cover a carport and turn it to a real greenhouse, all you need is wood running boards along the bottom, you can use 2x12 instead of cement footings and its heavy enough to hold it in place. Then just slap a piece of poly weave on, secure it to the wood framed footing via one foot pieces of 1x4 all the way around and you're in biz. Build end walls out of 1or2x4 to mount fans and intakes and call it a season. If you need more anchoring support, you can use the tie downs the carports come with or pound in some grade stakes and secure them to your baseboard/footing.

Hey all... anyone doing large greenhouses and or processing facilities pulling commercial power on property zoned ag/residential? Applied for 200 amp Ag service for shop and was told by PG&E that I want commercial not Ag service. Didn't seem to be a problem for them, just curious if others are experiencing the same. Thanks in advance for the input

they have some nice carports in the farmtek catalogs, almost made me consider just doing that and pulling tarp! but i need to have a permanent cover on my cold frames so they can't see any plants.

What size pots are you doing? What's your spacing between plants?

[Yes4Prop215]

since i have to keep the plant count low it won't be a true maximization of canopy sq ft. i am aiming for something similar to Fisher's setup with 100-200 gal pots in rows spaced as close as possible.

would love to just do a SOG of 50-65 gallon pots but then i would be asking for criminal charges on top of a compliance check. from what I've gathered, under 99 keeps things in the civil compliance jurisdiction. over 100 and they bring in the sheriff special enforcement unit to hit with cultivation charges.

Yea I'm planning on doing 99 plants this year. Can't decide on pot size. I'm going to run (2) 20x96 greenhouses this year. Figured I would do 49/50 in them, 2 rows in each greenhouse. Do you think I should run bigger than 65 gallon pots? Maybe I should bump it up to 100-120? Only going to have 10' of clearance so I was thinking I would have to pull a tarp and start flowering early.

At Rimol Greenhouses, we know cannabis growing.

Not sure I'd take their word for it, but I thought the package seemed well priced. The quality of the materials is questionable at that ticket...

[Backyard Farmer]

Rimol is who Envirotech and Gro Tech resell. It's all steel and plastic..

[FatherEarth]

So your negative experience was with enviro tech and was a service based issue?

Where you were satisfied with the quality of the Rimol material?

[Backyard Farmer]

The light dep part comes from another outfit.

Envirotech has "good" customer service, in that they eventually fixed every mistake, and even paid for what they damaged via fire...but they have horrible customer relations and service in that they couldn't pack an order correct to save their life or walk up to a fully built frame with functioning ridge vent and framed end walls and construct the blackout kit that came with no instructions quickly

I just set up my Karmen's Greenhouse helper arm (it's just like the golden arm pretty much) and it just won't work on my 72x20x11.5 greenhouse with the silver and black heavy duty black out tarp I got from Gro Tek. It's just too heavy..I can see it bending the arm down..and...there's no way one person could do it regularly. Anyone have any recommendations on tarps? or maybe some tips for the helper arm?

I don't want to go with breathable blackout tarp from forever flowering..wayyy too expensive and not very durable..and, I'm a little hesitant to go the doubled up panda plastic route because I'm not sure it would be that much lighter than the back and silver tarp and it can be unwieldy. looking for something in between and I need to be able to pick it up in Norcal or have it shipped fast. I've been turning on cfls in the greenhouse @ midnight with no tarp and it's starting to freak me out.

Also, I just found out that the tarp Gro-Tek sold me as part of a package is a full 3' too short on the sides. I'm going to call them tomorrow and see if they'll stand behind what they recommended.
