Gardeneer,
In the Czech language is called cold hotbed. English translation is not like me, so I wrote a wood frame.

I never cloned determinant tomato. Yesterday I cut up a tomato 0-33 and clones planted. I wonder how plants from these clones will evolve (leaves - inflorescence).

I began to harden tomatoes 0-33. In the morning I put it on the balcony when there is 9-10 ° C. To the apartment returning late at night when the temperature drops to 6 ° C.

PS.: have trouble re-sizing photos, I need a simple program. The problem is that I'm still just Windows XP, which is not supported. I deal with it with my son, who has not still time.

Hi Mr. Big,

Concerning re-sizing of pictures, I use a free website called Picture Monkey to edit my pictures: http://www.picmonkey.com/

Interesting approach, with the mulch over two raised beds and a trench in the center. I would never have thought of it, but it looks optimal to get moisture to the plants and also warm the sides of the beds and the root zone.

Two seedlings 0-33 looked like this after last night when the temperature dropped to - 1 ° C. Tonight was warmer (+ 3 ° C), but the next two nights should be still frosty below 0 ° C.

These grooves are there to facilitate and accelerate watering. I used to grooves with wood shavings mulch, this year I'll be the first to use black cloth, through which water seeps in.

Very nice! Very impressed with the O-33 seedlings as well. I have some seeds of this one, and I will start them this weekend I hope.

Evaluation of experiment with growing seedlings 0-33 in cold conditions.
Seedlings were on the balcony 80 hours, temperatures were as vidětt the graph. Two days afternoon was sunny and the temperature on the south balcony was increased to 18 ° C, alternatively at 16 ° C. Seedlings withstand low temperature (- 2 ° C), but could not withstand the permanent cool below 12 ° C and began to dry for. It's me, sorry.

Hi Vlad, thank you for sharing. Since in the pictures it appears the growing tip has NOT been frosted, would you consider this evidence of a level of tolerance?

Very interesting. I've seen damage like this on some plants about the same age but newly transplanted into larger pots, when just a cold night followed by a daytime high only 10 C, so maybe 30 hours in that case.

But almost every year, we have about 80 hours in that temperature range - especially with days only close to 10 C and colder nights for three days in a row, usually in late may. I had a lot of varieties that tolerated the 80 hours or so with no damage. The difference, they were older plants. And they were already established in bigger containers, where the soil may have warmed already.

And of course, frost tolerance for a few hours is not the same thing as tolerating constantly low temperatures for three days or more. I think they are separate traits.
