GH, Hot & Cold?

dcarch · April 9, 2007

Now that I have my removable GH complete,

I have the temperature range set at 85 degrees daytime and 45 degree nighttime.

What would you do?

Thanks

In general, I'd think you'd want it a little cooler during the day (why 85F?), and a bit warmer at night.

Depends on just what you want to accomplish in that greenhouse.

I took a brief look at your other thread, and am I wrong in assuming you want to see at least a little fruit set on the plants before it's safe to remove "temp" greenouse??

If you were just trying to grow some nice stocky plants, a constant temp of 50-55F minimum would work.

In any case, I'd aim for above 50 at night, if possible/affordable in your area. Significant blossom drop will usually occur below 50-55F night temps, depending on the variety.

I set the daytime temp at 85 because I don't know better

.
I was thinking that would warm up the soil to keep the temp at night higher.

I am going to set the night temp at 55 degrees. I plan to remove the GH once the possibility of frost is gone, may be 5/1.

You only need 85 for pepper seed germination. And 75 for tomato seed germination. For growing transplants, I concur with Suze and some other folks that growing them at 55-60 will yield smaller, stockier, healthier plants.

I grow my transplants indoors in 70-75 and although they do fine, they are a bit lanky and never look as stocky as the transplants at the nursery. Of course after 2 months, you can't tell the nursery-grown plants from my own plants.

Actually, if they predict a warm sunny day, all the front panels can be openned for ventilation.

So, with 50-55 night time temps, what should your day time temps be for tomato plants. Mine are around 6" tall, potted up, and I'm planning to put them in the hoop house some time today. My first with the hoop house.
