Wow this grow has truly been inspiring keep those updates coming man!
My friend grows super skunk, ak-47 and bubblegum in a warehouse grow op (half organic soil and half coco but moving to all coco now), he trashed the bubblegum mother though but both his super skunk and ak-47 plants are amazing. Super skunk smells so dank you just brush against the plants and the stench gets released :)

These strains are both very potent and easy to grow with quite different effects.. Now hes looking for some new strains to add in (hes only been doing this grow for around 6 months so far) but I can recommend the super skunk its really AAA+ smoke!
Nice greenhouse grow. Is the only light through the roof?

Thanks for the tip on the Super Skunk. Not to be a snob, but we only use clones from growers we know, and of plants that we have seen grow and tested the final product. Fortunately, I have quite a few growing buddies producing some of the best buds to be found in Cali. The guy who gave us the Bubbas and Lavander cross has had the lights burning for the last 20+ years! He estimates that he's gone through over 1000 different phenos of 50+ strains to end up with his current stable. His grow op is a high-grader's wet dream. Without access to these genetics, I would of had to do a home grow for at least a year to find 1 or 2 truly special plants. It seems like here in Cali, there's only 2 grades of smoke: Top 1%...and everything else.

interesting.
im not in Cali (yet) but we got some great beans imported from an "award-winning" breeder friend from CA. sent us a bunch of OG Kush x Bubba Kush beans and thank Gd we in our little collective are growing the top 1% out here :)

Who drops the cash for the cost....you....or is it a pooled together thing??......like you have 10 members and something cost $1000....everyone shell out $100?????

Luger's got it right. Most of our members have serious health problems and couldn't afford to shell out the necessary funds up front. We started this thing for people who have really big medication needs and can't afford to pay dispensary prices. We have one member who can only vaporize kief...and he needs alot of it. Can you imagine how expensive that would be paying dispensary prices? The edibles we make for patients who can't/won't smoke are made from buds, not trim. There is no way to consistantly dose edibles using trim. Once again, this is a product intensive medication. By having an investor capitolize the operation, the patients can spread out the payback over a period of many years. Even with the loan payback figured into the med price, we'll still be around 1/2 what they would pay at the dispensary. Keep in mind, forming a private collective of this type is easiest if a group of patients get together and decide to collectively produce their own medication. Furthermore, we feel that our structure fits within the letter and the spirit of the current laws. If we find ourselves overproducing for our existing members, we may add a few more members on a case by case basis. I doubt I would (as many growing collectives do) sell overages to other dispensaries.

If you got genetics that good from one bag of seeds from one breeder consider yourselves very VERY lucky. I've found that there is a HUGE variety of quality within each strain. Even strains that are "stabe" show alot of difference from seed to seed. The reason I say that I would spend a year finding the right plants is that it can take 100's of seeds of the same strain from the same breeder to get, what I feel, is that one special lady, worthy of basing a multi light grow op on.

I hope you did get lucky and ended up with a real ass-kicker. I'm sure your members appreciate it.

Yea I built my glasshouse a few years ago, my grow is in a small room at the back. I just built a wall to seperate it from the main room. Its just the free sunlight coming through which is also dimmed by the frosted panels so I have to elevate my plants right up there or I get quite alot of stretch. I do have power inside there but I only run oscillating fans... I do have grow lights its just if I switch on a grow lamp in there the place lights up like an orange lighthouse haha...

Yeah, the wind could really cause a problem, eh? It's gotta be easy for one person, yet strong as hell. Maybe the blackout settup inside the greenhouse?
the blackout inside could work as long as the lights arent hanging(i think). the wires/chains that hang them would get in the way of pulling the curtain across. idk how u would get a light proof seal around them while still easily doing the curtain thing. maybe have the lights on the walls, facing sideways onto the sides/tops of the plants? instead of hanging from the top... they would still get most of their light from the sun

thats SO true! theres the really dank nugs, and the rest... lol

i could see that being a problem haha. maybe u could do a removable blackout curtain so the light doesnt get OUT. with proper ventilation it'd work

Hold the presses. I got it. Blackout option #2: Build a dark room onto the end of the bloom house and wheel the plamts into the room at night. It would be a pain, but with a concrete floor and plants on carts, it could be done. HVAC would become more difficult. I usually put a big fuck-all swamp cooler (or 2!) on the end on the green house. This creates a nice cool breeze right through the unit. I guess I need to ventilate the dark room as well. Probably need to dehumidify it also. Hmmmmm. Can anyone build on that idea?

maybe this is kinda off topic but .... can you build a hoop style green house w/o have any other climate control ? just have the ends open or somthing I'd love to give this a shot in the backyard. lights and black out arnt neccasary unless you plan on multiple harvest correct?

Yeah you could do that gardener I would just use 2x6's and plywood and built platforms like 8x8 or whatever size ans either put wheels on them or move em around with a pallet jack.

I also had a few ideas on how to blackout. One would be the tarp is inside, jus run 2 pieces of conduit down the entirfe length of the house, just below the cieling and then drape the tarp over that. Then you could just pull it and it would slide down the pipes. You could either hang the pipes from the cieling or have posts coming out of the ground to hold them (that would be better cuz then you could hang other things off the posts too) and you could use multiple tarps that overlap so you don't need one huge one. So its inside and the wind won't mess with it. Does this make sense?

Also if you built the house like a triangle instead you could just have 1 tarp roll down each side and when ur not usin em roll em up to the top n strap or tie em up.

I thought that might be hard to understand so I scribbled out the one I think is the best idea, with the tarp on the inside sliding down conduits. I know its a horrid drawing its just to help explain what I meant



A scribbled side and front view. This would be incredibly easy to build.

Just curious what type of material people have used to keep moths out of their garden?
Last season I had some greenhouse plastic and screening and some still got thru! :P

Duke, it really depends on your local climate. Here in so cal, it's not too much of a problem. We live in a breezy area close to the beach, so there's some natural air movement. Personally, I'd install a swamp cooler on one end and vents on the other at the minimum. The fan runs all day and the pump is on a thermostat.

I dig the drawing. That dude pulling the tarp is priceless. It looks just like Helper D.

I like the idea. I like it alot. It also enables us to do everything in one house...just cover a section. This is a winner, Wood. Nice work.

Right on bro I don't kno where ur greenhouse locations gonna be if its in public or not but I read about some paint for glass that let's the light through but you can't see through it ill look for it later but I'm sure there is some light lost
 
Wood covered it. Thanks. I believe that 62 watts/sq ft isn't overkill. While the yield may remain close with less light, I wouldn't get those ultra dense nugs that california patients expect. If you're using less than 50 watts/sq ft, you're going to lose yield. I have a friend who uses 80.
Wow, Okay. With CO2 at ~1500ppm could one potentially use 100+watts/sq ft?

I was thinking of building from framed walls and sheeting the walls in opaque Lexan and the roof in clear Lexan. I've used a light meter to check tranmission through opaque Lexan, and the lighting strength is brighter than from a 1000watt HPS 1 foot from the bulb. Thats good enough for me. Besides, the roof would be clear. Another benefit to corrugated Lexan is that it breaks up the outlines. Even through the clear, you can see that there are plants, but you can't see what type.

Every greenhouse I've had, I've used a traditional framed structure. It makes fan, light, and shelf installation soooo much easier than with purlin and hoop construction. I also like having 6' vertical walls to get large plants right out to the edges. The last one I framed with steel studs coated with Boeshield anti corrosive (it forms a waxy coating). Steel studs are cheap and 2 guys can build any reasonably sized house in 1 day. I keep looking at the commercial greenhouse kits, but the nice ones are very expensive and the cheap ones are very wimpy. Since this thing needs to be 100% climate control, I'll need plenty of options for roof openings, fixed exhaust fans, and possibly a ductless mini split air conditioner.
