I would be interested to hear other professionals thoughts on different lighting systems.
We run a primarily outdoor and greenhouse operation but have some smaller indoor rooms. Some with LED (Marspro II) and some with HID - we are testing these more for off season production and mother plant and clone preparation for outdoor and greenhouse deployment in spring/summer.
We are developing plans for an integrated greenhouse (3000 sq+) with assisted lighting. Here in Canada we can have some pretty poor runs with the sun (there were 50 hours of sunlight in the last month for eg) for about 4 months of the year.
Has anyone else had experience with deploying a large assisted lighting system? Reflections on energy usage? Light spacing. What has worked and what has not worked so much?
