Instructables

Step 1: Materials and Tools

Materials:
Black plastic (I used Panda Film but this regular is fine)
Foam fruit box
Tape (I used masking tape but duct tape is better)
Small fish tank heater (this can picked up for around $20 AUD)
Perlite
Seedling tray (any kind so long as it fits in the box)
Water

Tools:
Scissors

Step 3: Set temperature & insert heater

The temperature for germination varies form plant to plant but you can find a good guide to seed germination temperatures here.
For tomatoes we set it to 26 degrees C (78.8 degrees Fahrenheit).
Then place the heater on the bottom of the box with the suction cups facing down.

Step 5: Put in the tray

Place the seedling tray into the box then fill each compartment with the Perlite.
WARNING: Perlite is made of silica, DO NOT breath in the dust!

Step 6: Plant the seeds

Plant one (1) seed into each of the tray's compartments and then turn on the heater. To keep the heat in place a small sheet of black plastic over the top. Once the seeds have sprouted this is not necessary. All that is left to do is wait until the plants are big enough to transfer into either a hydroponics setup or a regular soil garden patch.
