White Cabbage "Ijunskaya"

* Growing cabbage seedlings indoors is a troublesome and difficult task, since not all gardeners manage to get good seedlings of this crop, but those summer residents and rural residents who have a greenhouse or other insulated shelter find it easier to cope with this task...
To get good seedlings of white cabbage, red cabbage, Brussels sprouts and Savoy cabbage, you must follow the following regime for growing it: the air temperature from sowing to emergence should be at least +20°C, and for 4-7 days after emergence +6+10°C, in the following time - on sunny days +14+18°C, on cloudy days +12+16°C, at night +6+10°C, with a relative air humidity of 60-70%. Good ventilation of seedlings is required.
The conditions for obtaining good seedlings of cauliflower and kohlrabi are almost the same. The only difference is that for these types of cabbage on a sunny day the temperature should be slightly higher (+16+18°C), and the relative humidity should be within 70-80%. (In a regular apartment, if the air is not humidified, the relative humidity is usually 45-50%).
Almost all types of seedlings immediately after emergence should be grown for a certain time at a lower temperature compared to the one that was before emergence. Unfortunately, this requirement is rarely met, so the seedlings often turn out to be elongated, weak and pale, and this leads to a decrease in yield.
