“Why not put them outside in a small tray with water in the bottom? The problem might not be so much sunlight but soil temp. Squash like it warm.”
I had them in a tray in paper cups with holes in the bottom and around the lower part of the cup, with water in the tray. The soil got wet so poured the water out of tray but made sure the soil did not dry out. Putting them outside in 102-105 temp. I figured would cook them, plus have to keep double netting over them due to squirrels/birds eating the seeds.
Today, I put the one with the seed that seems to be germinating in the small greenhouse outside without zipping up the greenhouse. Still think it will get too hot in there for the seed. Today it is cloudy so seed won’t get too hot.
The house is cool so maybe put the seeds outside under the roofed deck and cover them with net. That will keep them warm but not in the blistering sun. Once they are up, could put them for a brief period in the sun, then put them back under the roof.
That’s why I’m thinking the grow light assembly would work inside without all the watching and moving and watching. This unit, actually the four foot long one instead of the two foot I posted, has a fluorescent grow light that one puts close to the seeds to warm them before they come up. When they sprout, the light is moved up (it’s on a pulley set up), as the plant grows.
It appears plants like lettuce can stay there and grow during winter for food.
There are over 400 customer comments on this particular grow light unit and I’m on page 3 of 41 pages of comments. Seeds are sprouting and growing. It appears the best quality of this unit is the ability to move the light down and up according to the growth stage of the seeds/plants.
