Looking for Tower Garden Curriculum?
This seed starting procedure has been adapted for the classroom from a procedure shared by Joe of level2concepts.com. It’s a little different than what’s in the Tower Garden manual, but works well in a classroom. This procedure works best growing herbs like basil, and lettuces like arugula, red salad bowl, buttercrunch, pak choi, and black seeded simpson. For the full procedure to use with other crops, visit www.tgardener.com/seedstarting.
Use the pH test kit that comes with the Tower Garden. Put 5 ml of water in the vlal and add 5 drops of the solution. Compare the color with the colored dots on the test paper. For a small amount of water ,like the apple juice container in the picture, use just a few ml of the pH – or pH + at a time to adjust the pH. Don’t stress out if you can’t get the pH exactly right. Most plants will do fine if the pH is close.
Give each student a rockwool cube and pour out several seeds onto 3X5 cards. The students can count out seeds and place them in the hole in the rockwool.
Cover the container so that all the seeds are in the dark. (A file folder works well for this.) Place container on a counter or in a cabinet.
Check each morning and evening (or when school is out) for sprouts. Replace the water each day. Most lettuce will only take two days to sprout.
It’s important to uncover the seeds when they sprout and place them on the Tower Garden base and turn on the lights.
Replace the water each day with 1/4 inch of water.
This basic procedure will produce fairly good lettuce for classroom use. If you’d like to grow better plants, visit www.tgardener.com/seedstarting for a more involved process.
