Wondering how you guys that grow a lot start your seeds, not just in spring before the last frost but throughout the year for rotational and successive planting. Specifically, does anyone use grow lights? If so, any specific set up?
Starting from seed seems to be the bain of my existence. Even when I manage to get good germination, the seedlings get too long and lanky to support their own weight and just never live to become a full fledged plant. I think it's a problem of not enough good direct sun so ordered one light today to tryout and see if it makes a difference. Dam things aren't cheap either.
I start about 25 flats of seedlings each year. Flowers, Cole crops, onions, celery, peppers, tomatoes, pumpkins, gourds and squash, etc. Only time I buy a plant for the garden is if I need a variety of pepper or something that didn't germinate well or I forgot to order seed for.
Everything is started in my basement and lives there until it's warm enough to go out in a coldframe. I will start some flowers the first week of February, and continually plant more up until about mid May. I'll start again in another week or two with fall Cole crops and Chinese cabbage for my kimchi.
Been doing this for 15+ years. Started with T12 fluorescent lights. Moved to T8 and now am using LED shop lights of at least 5000k. Stay away from anything in the 3500k to 4000k spectrum, those have too much red light. Blue light is what you want for seedlings. Cool temps are also important after germination, really don't want anything over 60-65° for vegetative growth. Keep the lights close to the plants (3-4”) and keep them on for 16hours a day.
Expensive full spectrum LED lights are not needed for growing transplants. The only reason for using those is if you are planning on growing a plant to maturity under lights.
I think somewhere in this thread I posted pictures of my racks that are made from 3/4" pvc. The main rack has three shelves that each hold four 1020 flats. I am currently using 3-4' LED lights per shelf. I used to use only two lights per shelf with fluorescent lights, but the LED Lights are so narrow anymore, I moved to three.
In summary, cool temps, 5000k LED shop lights for 16 hrs a day.
Im assuming the light you ordered is a full spectrum "grow light" if so I'd highly recommend returning it if you can and pick up some $20 LED shop lights. Pair that with $20 or so in PVC pipe and fittings and you'll be on the way. For under $100 you could probably put together a two shelf system for up to 8 flats.
Edit: There are a couple pictures of my setup on the first page of this thread.
