low wattage indoor growing (seed starts)
#1
In years past I have used our spare PV watts during winter for growing romaine using an intense LED light. (In summer we use the power for air conditioning). This year we are trying to do various vegetable seed starts and need a larger area than the LED light can handle due to the size of the seed trays. These are plants that are going to be planted outside eventually when they are big enough to survive the rats and cardinals so they can't be leggy where the wind and rain would punish them. We're not growing weed so don't need a vegetative growth solution. But we do need the lowest wattage solution possible so that we can run it off grid as much as possible.

When we used to house parrots indoors we used T5 fluorescents to mimic the sun as much as practical and I remember having to shop the weed grow stores to get them and they seemed to be energy efficient but that was at least 10 years ago.

Recommendations? Ideas? We've tried starting the seeds outdoors but the pest pressure is insurmountable.

I don’t know about the lights...
but I start vegetables & grow sunflower shoots outdoors (in an open sided greenhouse) by forming metal cages around & over the trays. They keep out almost everything. I use metal hardware cloth with the 1/4” grid.

That's a great idea that we are going to use one day but we are always going to have the indoor option because of RLW.

Can't help with the lights but to help with the sturdiness run a small fan across them from the side as soon as they sprout. They will grow up much stronger and wind resistant.

A weed growing book will probably have the best answers.

Basically, go for the most effiiency (lumens per watt) and remember that luminous efficacy decreases with the square of distance. LED produces less heat than T5 or HID so the lights can be closer to the plants; more smaller lights will probably work better than fewer, larger lights. LED is also directional whereas other technologies lose some efficiency to the reflector.
