1. Cut the bottle in half.
2. Use a Phillips screwdriver and a hammer to punch a hole in the center of the bottle cap.
3. Cut a length of yarn/string about 1′-1.5′ long, double it over and tie a loop on one end.
4. Thread the yarn/string through the hole in the bottle cap so that the knot is on the inside of the cap.
5. Add potting soil and seeds…
6. You need to water the soil from the top the first time in order to make sure that it is uniformly wet and that the string also is wet.

Materials :

• 3 standard “cattle panels”.
• 2 rolls of 10’x50′ clear plastic. User a heavier grade. I used 6 mil.
• 1 16-foot 2’x’4, 3 8-foot 2’x2’s, 1 8-foot 1’x2′.
• A package (100) of 8-inch zip-ties.
• 2 rolls of clear duct tape.
• 1 roll of standard electrical tape.
• 2 simple door hinges, and a simple handle and latch.
• 4 2-foot sections of rebar.
• 2 20-foot pieces of PVC. Schedule 40 is okay, but lighter grade will work better for this.
• 2-inch wood screws.

Most patios take time, and days of effort, to build. But a small, detached patio like the one pictured here comes together quickly with minimal effort.

Think of the possible uses for this circle of bricks. You can tuck it into a perennial border. Or place it in a remote corner of your garden, where you can linger at day’s end over a glass of wine, or on Sunday morning with a latte while perusing the papers.
Tools :

• Rotary tiller or spade
• Rake
• Carpenter’s level
• Tamper
• Hose
• Rubber mallet
• Bench broom

Optional :

• Bucket for mixing mortar
• Grout bag
• Trowel
• Rag
• Burlap

You can find the Step-by-step instructions in Here

How To :

• Step 1 : Lay out the edge of the border with a garden hose, using the brick pattern as a spacer. Make curves gradual and smooth.
• Step 2 : Dig a 4-in. deep trench about an inch wider than the brick pattern, using a square spade. Cut the edge along the grass smooth and square.
• Step 3 : Cut landscape fabric to fit the bottom and sides of the trench and dump in about 2 in. of sand. Smooth and flatten the sand with a block of wood.
• Step 4 : Set the bricks tightly together so the tops and front edges are even and about 1/2 in. above the soil. Sweep sand into gaps and pack soil against the backside

Any greenhouse has four basic requirements:

• Warmth: a heating system (mechanical or natural)
• Moisture: an irrigation system (manual or automated)
• Protection: from the elements and pests
• Control: of air circulation and temperature (with electrical systems or by manual maintenance)

Tips :

1. The plastic film that covers your greenhouse will degrade in a few years and need to be replaced. The ideal method of disposal is recycling, but agricultural plastic recycling is not available everywhere, so consider storing it until you can dispose of it in an environmentally friendly manner.
2. This type of greenhouse is not good for areas that receive high winds or heavy snows. To prevent against collapse under snow, reinforce the greenhouse midrib with EMT conduit or steel rebar.
3. Choose wood for your foundation and door frames that is long-lasting and sustainable. Cedar, cypress, and hemlock are affordable options; redwood is also a good choice but is more expensive.
4. To keep conditions more constant, you can cover your greenhouse with a shade cloth, or locate it near deciduous trees that provide some natural afternoon shade.
