Yesterday I saw a grown tomatoes and cucumbers in greenhouses ultramodern. Much of this process I was surprised.
Now I am in Latvia. Yesterday visited the greenhouses near Riga.
Soil in the greenhouse, not at all. "The beds" hang at a height of about half a meter, to work do not have to bend, taking care of plants.
Instead of land - is such a basalt wool.
Each root two tubes of water and nutrients summed.
Interestingly arranged "conveyor belt" of cultivation. On the lower branches of ripen tomatoes when they ripen, their tear and cut branches. All the whip lowered (it is tied to the beams at the top) and starts ripening tomatoes next. The length of the stems with cut branches by the end of the cycle reaches twenty meters, the stems wound up at the bottom.
Each branch with tomatoes supported by a plastic support, not to break under the weight of the bunch. Sticker on one of the cluster of tomato paste more until it matures.
Even the process of pollination automated. Nests bumblebees are boxed, the outputs of which are opened and closed by automation.
In this farm tomatoes light 600 watt sodium lamp, and cucumbers 200-watt LEDs.
In addition to the upper lighting shining on cucumbers side additional LED lamps.
Measuring the spectrum of LED lamps, which are used there. It seems that they are very unusual. I will study when I go back to Moscow.
In a greenhouse maintained the desired temperature and carbon dioxide levels. On the leaves periodically and automatically sprayed water.
growing cycle - 4 months (more lashes are too long and the yield falls). After the end of the cycle greenhouse cleaned and disinfected. New seedlings are buying in Finland (among other things for two and a half euros per share).
When the greenhouse is a small shop (the bulk of course goes to the grocery chains). Cucumbers cost 3 euros per kilo, tomatoes 4.2 euros.
Here, up on this "assembly line." :)
And this is me in cucumbers. :)
P.S. I tried and cucumbers and tomatoes straight from the tree. Tasty enough. Not as tasty as the ground, but not "plastic", as often happens.
