The 11 in. x 22 in. Tall Clear Plastic Dome Dual Tray Kit with 4 Domes, 4 Standard Flats, four 72 Cell Inserts and a Quad Heat Mat comes with everything needed to begin plant propagation. Use the four included compartmental trays to start 288 separated plants using your favorite growing mix. The quad heat mat works best when on a flat, dry surface and plugged the cord into any 120-Volt outlet. Included seedling trays are to be placed directly on top of the heated mat. For best germination results, place the tall propagation dome over the tray and keep it under a T5 fluorescent lighting (approximately 300 ft. to 800 ft. candles). Direct sunlight or high HID lights may be too intense for seedlings and as a general guideline, seedling and clones grow best with temperatures of 70° to 80° and humidity range of 50% to 60%. Please be sure to research your particular plant as temperature and humidity requirements vary for different species and hybrids. Kit includes: VTDK4 - Qty: 4 - V726220 (standard flat 72 insert), Qty: 4 - VSFB900 (standard flat), Qty: 4 - VTD300 (tall dome), VSEEDMAT20 (Medium four Tray Seed mat) and VDT (Digital Heat Mat thermostat).
