Grow Lights

Now there's a thought also.

Is that yours? that's the nicest, tidy-est hoop house I've seen! Beautiful.

Very nice, beautiful design and execution.

Someone much more skilled than me I admit but I have made them in the past that were similar.
It is a cracking example

The seedlings shown above are too young to be kept outside in any kind of greenhouse, big or small. A nursery with a warm temperature and artificial light is a must. A greenhouse won’t make things easy : light will be OK but temperature can get very high if you forget to open it, watering will be more difficult. To sum it up a greenhouse requires constant attention when a timer and a thermostat will do most of the work in a nursery.

That is not my experience, I put 2 day old seedlings much younger than his out in a glasshouse in daytime when outside temps were 50 F. His temps are much better than that and not hot enough to burn them. He has perfect conditions for it at this time of year. Everyone I know uses a glasshouse.

Update: So far so good on the new lights, I really like them. The digital timer is a great feature, there is a 3 to 5 day acclimation period and Viparspectra suggest a heigth of 36" to 40" away until the plants get used to the light. Then I can move them closer. the temperature on them is in the 70s now.

They were just repotted so I didn't want to shock them too much, they seem pretty happy considering. Used FF Happy Frog so there should be some nutrients in there (hope that was okay, I was going to use Light Warrior but hydroponic store guy suggested the Happy Frog).

Placed some of the seedlings in the cellar with the fluorescent T5s, the temp on the them is in the '70s and I think they do look better for it. Ran a fan on them for awhile, also on the LED plants.
The jalapeno peppers and basil look like they had a growth burst under the LEDs, they are not repotted yet --

I'm not looking for fast growth on the tomatoes as I have 4 weeks to go before planting, I've got a lot to do with the garden area so being a little late to the game works for me.

Looking good!

I think 83 is a good temp for seeds and long as there is some humidity.

I use 1000 watt HPS (5) lights to start my seedlings indoors. The heat from those lamps heats my house in the spring. Temps in grow area are about 80-83 and I keep humidity around 60-70%.

Happy growing!
