Where to sow
When do we end the resting period of our plants and do
we start watering?
A useful rule to follow is, "If in spring the temperature in the
greenhouse rises above the 25oC and is maintained for at
least 4-5 hours", of course without the extra heating source.
Choose the first of a number of sunny days and
water, the substrate with water brought on temperature of
ca. 15 tot 20oC.
The next weeks we will not ventilate! This creates a humid climate comparable with the climate in the seed
is not always necessary. Keep the floor wet if necessary and water if the
pots are dry.
The plants will show life within a couple of days by sucking the water
buds will show and a new period starts. These weeks are comparable with
the conditions at their original habitats, where the spring starts with
lots of rain and a humid climate; the period that seeds germinate and
young plants could grow before the hot sun of the summer does its
After four to six weeks we start slowly to adapt
the climate in the greenhouse to a lower humidity level and careful
ventilation is applied. The first days we open the thin insulation film during
daytime and close it at night
and it is removed completely after one week. The screens are closed after
sundown and opened at sunrise.
This way we adapt the climate slowly to allow ventilation during day and
night time in the summer, whereby the temp could drop to 10oC
once in a while without risk.
