Want to plan an experiment with Fast Plants but not sure where to start? This handy materials kit provides seeds and all the materials needed to set up 4 separate deli-container watering stations. You determine the experiment and the parameters you would like to test. There are enough materials to conduct 2 complete growth cycles (ensuring 8 separate trials, 4 at a time). This kit uses seed disks instead of individual seeds, saving time and ensuring that plants are spaced properly for growing requirements. Never worked with Fast Plants? Don't worry; planting instructions are included to help you be successful. With this kit, you can observe the complete Fast Plants life cycle in 35 to 40 days. Note: The minimum light requirement for each watering station is 24-hr, cool, white fluorescent light placed within several centimeters of the plants' growing tips.
