Miniature, cuttings-starting, white plastic greenhouse

Step 3 Securing of the plastic with bricks + greenhouse operation

Now, we'll firmly secure the plastic with the stones. We will first fold the plastic on all sides and then lay bricks on top of them. A single fold for each long side of the greenhouse will suffice, but the short sides of the greenhouse will need more rigorous folding. Make sure all sides are well sealed when you get the greenhouse operational (by eg applying water and increasing humidity for letting the plant cuttings take root) To seal everything up well, we may place a single brick every 80cm of plastic and do so for all the sides of the greenhouse.

After having the greenhouse well sealed up on most sides, we keep a single side open and place in the seed trays trough this side. Alternatively, if we intent to sow (which I would not recommend; preferably use another technique for this purpose), keep more sides open. Finally, lock it all up.
