The seedling tent seedling growth stimulator circuit is composed of the transistors V1, V2, potentiometer RP, capacitors C1, C2, speaker BL, power switch S and battery CB, and the circuit is shown as the chart. V1, V2, and RP, C1 form a simple pulse generator. RP selects a small organic solid potentiometer or variable resistor. C1 chooses the monolithic capacitor or polyester capacitor; C2 selects the aluminium electrolytic capacitor with the voltage in 10V. V1 chooses 3DG6 or 59013 NPN silicon transistor; V2 uses 3AX31, 3AX81 or 3AX83 germanium PNP transistor. BL uses the 0.25W, 8Ω electric speaker. GB selects the 6V small-capacity maintenance-free battery. S uses the monopole tumble switch.
