Twelve days ago we were able to plant around 740 cucumber plants. We are using this year as a sort of experiment and therefore have no real heating system in place. The temperatures have not been ideal causing the plants to lose a bit of their bright green color, but they are growing. Most had 2-4 soft leaves when we planted them and now have 5-8 leaves. They are planted in 8 rows 3-4 ft. apart with 10 in. between plants.
We hung strings from the ceiling for the plant
s to climb and we are training them to go up the strings. We monitor the temperatures, and open the windows if the temp goes above 30C (anytime the sun is out) and close them when the temp goes below 20C. It is amazing how much warmer it is inside during daylight hours. When it gets a bit warmer we have some ceiling fans we are going to install vertically in the two front windows to help with cooling. 
For watering, we have sprinklers hung from the ceiling and drip tape in each row. The well (that was installed last fall) is directly outside and is used to fill an old 3000 liter tank in which we mix fertilizer with the water before watering. It seems to work well to use gravity to water (with the drip system), but we may install a pump to speed up the process.We hope to have fresh cucumbers in a couple weeks.
