Greenhouse in a Bottle

with dish soap and a little bleach,
and well-rinsed with water

Organic seed-starting medium | Seeds
Combine our toilet paper tube
seed-starting idea with this simple mini-greenhouse, and your seeds will think
they're growing up in the Taj Mahal!
Do this several weeks ahead of the last
possible frost in your part of the country; the seed packet should tell you how
far in advance of that frost date you should start your seeds indoors.
Simply make four half-size t.p. tube
seed-starting containers, and fill with moistened seed-starting medium and your
seeds. Water in slightly.
Then take a 2-liter plastic soda pop

Take the rounded bottom piece. Into it, place
the four "loaded" t.p. tubes. They should snuggle up against each other.
Then "screw" the longer top part down

your plants can move from their mini greenhouse into the soil outdoors!
Longtime gardeners re-use the soda bottle
tops as a "cloche" (cloashe) to protect seedlings from the wind - simply
"screwing" the top part down into the soil around a tender plant.
They also keep their two-part mini
greenhouses from year to year, to recycle and "rebuild" the greenhouses for
next year's crop!
