Buying a bunch of seeds is nonsense.  You can just save the seeds from what you eat.  I threw a bunch of cantaloupe seeds from One Cantaloupe and have what looks like 100 plants.  The seeds are sprouting like crazy.

The same can be done with Watermelon.

Jalapenos.

Stone fruits like peaches.

Cherries.

Lemons.

Tomatos.

Cucumbers.

Apricots.

Pumpkins.

Peppers.

You name it.  These seeds are all free.  You throw them out.  Try growing them.

At $4.00 a cantaloupe I am going to save myself a fortune with my own home grown Cantaloupes.
