An ideal growing medium for annual and perennial flowers, vegetables and house plants. Composed of equal parts of shredded sphagnum peat moss and fine grade vermiculite plus just enough nutrients to sustain initial plant growth. Mixture will produce acceptable plants but for long term growing a balanced water soluble fertilizer is applied weekly. 4-Quart bag fills 35-3" pots.
Instant planter, just add water then seed or stick in cuttings as desired. Peat with proper starting nutrients are compressed into small wafer, when water is added, it expands 7 times its size into small post 1 3/4" x 2 1/8" high and covered with plastic net. Plant roots grow right through pellet permitting replanting without removing pot. Pack of 24.
Multiple program timer turns on automatically two or more times in 24 hours. Grounded for safety when used in three-prong electrical outlets.
Unique features include flexible, shatterproof material, and no-drip cover. Exclusive design forces condensation to remain in the tank. 10-1/2 in. x 7 in.
Great for creating terrariums, small aquariums, or as a critter cage. Solves the cracking and breakage problem of rigid plastic and glass tanks. Unique features include nestable to save storage space, flexible, shatterproof material, molded foot pegs that prevent scratching and temperature transfer, and rounded corners for easy clean up.

A unique hands-on science teaching aid that is visually exciting to students. Students are able to watch what they see and read in a science book happen right before their eyes. The Teaching Tank is approximately 12" x 12" x 1/2" and can be easily dismantled and cleaned with mild soap and water.
This expansion kit will allow teachers, parents, and students the opportunity to turn their original Teaching Tank into a small aquarium in about two minutes. With this wider tank, a whole new variety of experiments can now be completed.
This kit can be highly motivational to students for regular class or independent study. Both teacher and student guides are professionally produced and include easy-to-follow directions. Illustrations identify skulls of common prey species and charts are provided for students to record the data collected. Students learn about energy transfer through food chains while observing skeletal features which identify prey animals consumed. Additional studies can be conducted to evaluate animal populations within the owl's habitat, make calculations to estimate the biomass of the prey animals, or investigate the skeletal anatomy from the taxonomic features of the prey animals. 15 student worksheets, and Teacher's guide. Grades 7 and up.
