Outdoor greenhouse in the winter

Hey everybody I just want to see what everyone thinks about this idea I'm about to try. I have done a couple crops out side during spring and summer seasons. I usually do an indoor crop all your long and want to see what people think about growing during the winter time inside of a greenhouse. I currently have some sour diesel plant growing inside of a pretty big greenhouse that's not heated at the moment, and the buds seem to be going just fine turning extremely purple because of the cold temperatures at night. I know the buds would be a lot bigger if I substituted light and brought in some sort of heat also to keep from the cold chilly nights in Southern Oregon. But what I'm wondering is my thought is to build a new greenhouse that's a hoop greenhouse with plastic sheeting over it and it's made out of PVC if you haven't seen 1 look them up on the net. I was thinking about keeping it heated with an oil heater and . I plan on vegetating my plants indoors and till their about 2 to 2 and a half feet tall and then putting them outside to flower. Does anyone know anyone who has done this and saw the results? What do you guys think? Thanks everybody for the input!

Only problem i see is the "rainy weather" that Oregon is famous for. Here in cali its been cloudy for days. This means they will probably get little direct sunlight , and im sure you know how that will effect your plants. I would def add some supplemental lighting (23 watt cfls at 2700K work great for flower and are cost effective) everything else seems fine and should workout for you

He has a green house. I could relate. I had a winter grow. And instead of putting a heater I turned on the lights at 3am or right before the morning frost note: gets up to 20 degrees change before sun rise. I did half indoor then take em out till the sun set. Then take em in for an additional 5 hours just to keep em from flowering. Didn't matter cause they flowered anyways till a the whole month. Of April. Just about 8 and revegged for an additional harvest. 2 harvest is better than one

I have a Green House and a bunch of my seeds got all over the GH floor and they sprouted. Two are about 6-8 inches tall with female hairs showing and stinking up already and the others are 1-3 inches tall and still growing from what I can see. Im still in the middle of making my GH more sturdy since where Im at gets alot of wind from time to time. I think I might up root a few and put them in pots or maybe just leave them alone. I want to add raised beds to my GH and their in the way I had the idea of picking up some Teens from Cloneville and putting them outside to flower in January but do you think it will be worth the $30 a Teen ?

I understand that he has a greenhouse but a greenhouse doesn't create sunlight last time i checked. Theres a reason people dont grow outdoors in the winter. Not impossible, but he needs supplemental lighting and a greenhouse would give him plenty of places to hang lights

Isn't there a difference between a green house, and a polyhouse.

I can't see out of my greenhouse as it is covered in snow at the moment.

I am not familiar with your area, but if it's rainy and gets colder over the winter you are going to have real problems with mold. Off course you could add supplemental lighting, but then does that not attract other problems? (i.e most people grow with lights indoors). I guess if you are medically legal you are probably not worried about that.

The issue you then have is creating heat in a cold and damp place. The heat will create moisture and then mold will come. A dehumidifer will help, but also creates some heat and most dehumidifiers will not work below certain temps. Anything below 5 degrees celcius your plants will not be happy. If you can get round that the plants will grow, but due to sun positioning it will not be a very optimal harvest imo.

Hope the info helps.

build hoophouse inside greenhouse if possible...justa thought...peace
