Pretty much year round I get 12 hours of direct sunlight in my backyard, perfect to flower, not so much to veg. Last fall I had plants in a 10x20 greenhouse under 2000 watts for 6 additional hours, 3 in the AM before sunrise and 3 in the evening after sunset for a total of 18 hours of light. But, when the cooler temps hit late September and the sun tilted in the sky they knew what time it was and started to flower regardless. Not even running 3000w worth of electric heaters at night and keeping temps above 60 was enough. Swings of over 30f were happening tween night and day, no good.
So, I'm building a bigger better insulated greenhouse. I popped for 200' of 3.5mm Solexx, and construction is about 1/3rd completed. The new hoop house is 17' wide by 28' long with 28' archs from ground to ground. I also bought a 30,000 BTU natural gas heater to combat the temp drops we get at night here in the South West desert. Come summer time the Solexx should also really keep the heat out too.
A dividing light block wall down the center that rolls up and down automatically will happen as well. I want to both flower and veg at the same time, and my goal is to be able to do both year round whenever I want/need.
My question:
What's the best lighting schedule to run to keep mj in veg during winter in a greenhouse?
I'm sure temps had a lot to do with them telling me what time it was this past fall, but I'm not sure if a few hours at the beginning and end of the day really fools them once the days get a bit shorter and the nights colder.
I've read back in the day before electric light farmers brought gas lanterns into the barn around the plants for an hour in the middle of the night, but I've never tried it.
Thoughts?
Here's a few day old pic.
I've got a bit of the Solexx up, the back wall up, and the front framed and doored as of today.
