Seedlings look good - nice and sturdy considering no direct sun. Based on the weather outside of your window, it appears as if you are having a bit of a winter there! Is your winter this year aveage, or colder than average?

This year's January is colder than average (the gray lines).

I don't grow determinates as I want the tomatoes to ripen over a long period of time, rather than all at once. However, I have grown them in the past. The Siletz has superseded the still popular Oregon Spring because the Siletz is far better tasting. However, it may not be as good as later introductions by Jim Baggett of Oregon Stare University.

For what it's worth, the harvest window for determinate varieties can vary quite a bit by variety. I have had some yield continuously over the course of the summer, like Sunny Boy, Bradley, and Celebrity. "Determinate" as a biology term just means that each branch ends in a flower cluster and not a vining tip. There are a lot of commercially grown determinates that are meant to have a short harvest window, but they are not all that way. You also see the term "semi-determinate" thrown around a lot by seed companies, but I don't think there is even a precise definition of it. |

I have grown determinants that kept fruiting all season long (Siletz )and some that were finished after the first flush (Silvery Fir Tree). I don't get the "semi" thing either. I think that is referred to compact indet which has slower and short indet growth habit. But it is still an indet.

It is not true that all determinate varieties ripen at once. Only some of which are bred for mechanical harvesting ripen at once. Determinant varieties really terminate stalks by flowers.
The important thing is that they are low plants (bush), because between the two inflorescence is only one sheet (indeterminante three sheets). I want to watch all my determinate varieties how they grow and record all data. For each variety I have in my computer in MS-excel separate table (picture). I will try to keep you informed regularly.

I agree that determinants are bushy. Some varieties make small plants in any conditions. I have found, though, that in very good soil, some determinate varieties do make big plants - big bushy ones.

Awesome, Vladimir!
There really are many different habits for determinates, ie plants that terminate in a cluster. Some are very small, others are taller, and the pattern of leaf vs cluster does vary a lot. The genetics are . But it seems that many different patterns can be stabilized, large or small. There is a lot of variation in the OP's I've tried. |

FWIW, there is a working definition of semi-determinate, used by some researchers, that they have at least six inflorescence on the main stem before termination. The typical 'determinate' will have fewer than six.

I had a Celebrity plant last season which is a semi-determinate. It produced until the summer temperatures of 115 every day put it to sleep, but come fall, it started blossoming again and put on about 40-50 tomatoes that were larger than it's first flush. I was really amazed. Too bad it tastes like cardboard.

When you first showed me your XLS I did not appreciate the plans you had for it. Now I see it in use, I am very impressed - this is going to keep you very busy. Questions: 1. When do you record the date of a leaf emerging? When it first appears from the meristem, or do you wait until it is a certain size? 2. Are you ok with me using the sheet for a couple of my own plants this year? Thank you for sharing, rg |

Hi Robert,
Ad 1) -germinated plant I record when the cotyledons are horizontal. -leaf I record when it is greater than 25 mm (1 ") -inflorescence I record when it is greater than 12 mm (1/2 ") -sucker I record when it is greater than 25 mm (1 ") -flower I record when fully opened -compare ripeness of fruit will be around for different varieties problematic. I do not know yet how I'll do it. Ad 2) Robert, I will be very glad if you use the same table as me. We will be able to exchange our data. I want to use this record also when growing tomatoes from Stupice circuit and also for the early Czech hybrids. Vladimír Last edited by MrBig46; February 1, 2017 at 06:06 AM. |

I transplanted the seedlings, each plant is 200 ml crucible. After 44 days from sowing they all have three or four leaves. To the time of planting to warm hotbed remains about 60- 70 days. For us this winter will probably long.

My seedlings , at 22 days from sowing , have 3 to 4 true leaves. But they are much smaller than yours. I keep them at cool temperatures , ~ 65F ( = 18 C). I have about 40-50 days to plant out in the garden. The only EARLY variety determinant that i have is SILVERY FIR TREE. My other early variety is STUPICE but it is indet. Goo luck and have a great season !
