My New Greenhouse

During winter, I'd been thinking about a new, more spacious greenhouse. I need more space to grow tender flowers and veggies, moreover to store there plants in wintertime. Also for growing seedlings in pots for transplanting outdoors, or for growing plants to maturity in containers. I chose the type of greenhouse, I decided to buy 'a hoop house' type or 'a tunnel' type to easily clean up the snow. The covering is to be policarbonate. 
When I'd finally purchased, the set of details was brought to the garden in April. It was a set of Aluminium frame, with 2 windows that allow to ventilate the 'hoop house', the arched roof, big door. It's said that is strong enough and is not to be damaged by heavy snow and high wind.

I learned it's important that the greenhouse would be mounted on a strong base that is well embedded in the ground, leveled in order to avoid any difficulty during the assembly.
The greenhouse assembly should have been quick, but there were difficulties with the place for it. I wanted the location of the greenhouse to be next to the berry bushes so 4 raised beds came up inside the new greenhouse.

I had to cut some branches of berry bushes next to the greenhouse back end. As you see the greenhouse has a window in the back end. The policarbonate sheets were first installed on the ends.

They said the actual assembly time depends heavily on experience of adjusters, in my case it depended on experience of my family-members. For two days off they have assembled a wooden base, an aluminum frame of a greenhouse, covered it with polycarbonate, made the door, windows and handles.

In the evening when the assembly came to an end I went inside. There was very warm and moisture ran down the walls. I immediately opened the door and windows to ventilate.

What can I say - my wish was fulfilled and now I have to equip my new greenhouse, make shelves, align the floor, put tubs with flower and veg seedlings. I'll take photos to show you how the greenhouse does. Can you share your experience in growth in such type of a greenhouse?
