Thinking about growing in a Greenhouse vs a Steel Bldg.,

What type of Growing System works best in an Open Span Greenhouse?

Does anyone out there know of any online courses, that may be available to understand how to grow Cannabis in a Greenhouse?

Any idea of any Legal Cannabis Greenhouse Grows that may be able to be a Mentor, to a Grower with 35 years of growing experience, inside, under lights? This will be for a Legal Grow in California.

Since you have the experience with lights. Why not set up something with lights in the warehouse. Green house is great, just have to choose which type suits your needs. Tons of info on the net, I find cannabis forums to be a bit limited on the greenhouse info. I was going to start a journal of my greenhouse this year but the ddos attacks here make me not want to post photos ahah.

Indoor will always get you more harvest per year whereas a greenhouse will get you mammoth plants with lower costs. I think the major thing is what sort of market are you supplying? For a lot of folks indoor is the way to go because you get a constant year long supply which is great for the buyers whereas with a greenhouse you just get one massive supply.

ALL OF THE ABOVE assumptions are flawed.

I've seen absolutely smashing results from greenhouse grows.

Whoever said you only get one run per year in a greenhouse is badly mistaken.

Costs can be well managed for either scenario, just as poor engineering choices up front can render your building uncompetitive whether it's a solid roof or not.

Depending on climate, you may be able to run your greenhouse year round with light depo and supplemental lighting.

Choices of HVAC, lighting and greenhouse technologies will be critical to cost per unit volume, appropriate combinations will be key.

I believe I can help you develop a solution that will put you well ahead of the competition for years to come, protecting your ROI even as the market price of your product continues to inevitably fall.

Cost of lighting always becomes the real issue. CO2 is another issue. The benefits of new greenhouses can make them a winner. That said a greenhouse in the snow will cost alot to heat.

Consider: location, amount of sun, temp management and Co2 costs. Pests can be reduced and managed quite nicely with "god bugs" and newer management systems. With all this new tech comes cap costs that become another issue altogether.

I know old thread.

Green house with supplemental lighting. You can achieve the same par as a good indoors setup with about 25% of the lights wattage. You are California that's a lot of free sun there.

I am complete newbie and I am planning to grow mine in our greenhouse which is part of our house. We have a bunch of plants there already. I am just concerned about light... How much should it have? It is autoflowering plant. Let's say our greenhouse currently has 16 to 18 hours of natural and artificial light combined. Is that OK for the plant? BTW it is spring time here now so we will have better weather and more natural light...

No problem for an auto flower. For a photo period plant it will only remain in vegetative state until you reduce light hours or black them out.

So I read I should reduce lighting to 12 hours in order for it to flower? Is that correct? LoL I was hoping it can do that by itself...

Greenhouse is better, but because snobby/spoiled pot heads is your market, you might want to do indoor

The most light you can give for as long as you can is best. Light cycle has no effect on flowering with a true auto.
