Squirka with a window frame.
If you have a greenhouse, you can start the garden season four to six weeks earlier and end it four to six weeks later than usual. The version of this structure offered by us is unlucky in the manufacture, it is small enough for the plants in it are within reach, and at the same time is large enough to become a good help when growing vegetables. In addition, this is a good way to attach old window frames to business, which may be at hand.

In the greenhouse, the danger of overheating and dehydration is much higher than hypothermia. Overheating is possible even in early spring and late autumn, during periods of maximum use of the greenhouse. Remember that even in the coldest winter days, the bright sun can increase the temperature in a greenhouse to 24-27 ° C, and this is permissible maximum. Provide the greenhouse with supports that will allow to fix the glass frame in the raised position when overheating can occur. The danger of hypothermia of plants is small, unless the wind does not blow right towards the greenhouse.
Old window frames – ready -made glazing for a greenhouse of this type. If you do not have unnecessary frames, you can buy them at flea markets or ask your neighbors.
The construction of a greenhouse begins with sawing lumber.
The board with a cross -section of 2 × 4 inch cut into three segments of 19 inches (a) and three segments with a length of 12 inch (b). These will be blanks for vertical racks.
The board with a cross -section of 1 x 6 inches, cut into three segments of 59 inches, which will serve as the lower boards of the front and rear walls (B), and five segments of 25 inch – for the side walls and the central board (g).
Cut the board with a cross section of 1 × 8 inches to 59 inches. It will be the upper board of the front wall (d).
Cut the boards for the posterior wall (E) and mowed sidewalls from the board with a cross section of 1 x 10 inches, as shown in the diagram on the right.
The sizes of a greenhouse of this type are due to the size of the window frames used. If the size of your frames differs from 20 x 29 inches, you will need to properly change the dimensions of the structure. In any case, fasten the window frames to the greenhouse with loops with the outstanding axis, which will allow you to easily remove them if necessary.
Production of a greenhouse.
Start with the manufacture of side walls, taking higher vertical racks (a) for the rear angles and lower vertical racks (b) for the front angles. The mowed upper edges (g) will provide an inclined position of the window frames, which will allow rain water to slide off the greenhouse and give plants the maximum amount of sunlight. Attach the front boards (c), (d) and rear boards (c), (e) to the ends of the side boards (g), (g) to make a box to get a box. Then attach the central racks (a), (b) from the inside with screws, then attach the ends of the central board to these racks (g).
Put the window frames on the greenhouse so that their upper edges are flush with the rear wall (they will be slightly issued above the box on the side and front), and mount the loops. To provide plants with ventilation, attach the lower ends of the undergrounds (for example, for tomatoes) with screws 1% inch to the inner front angles of the box, as shown in the figure. Screws should be screwed up so that the backups can rest and hold the window frames in the open position.
