Be sure to provide adequate light for young plants. Fluorescent grow lights provide a constant, controllable source of light that is better than winter sunshine. Leave the lights on for 14 to 16 hours a day and keep the bulbs 4" to 8" inches from the seedlings by raising the lights as the plants grow.
If you do not use grow lights, place the Deep-Root Seedstarter in a south or southwest window. Rotate it daily to prevent the plants from leaning toward the light.
After germination, most young plants grow best in cool air temperatures (65 to 70 degrees F). This will help reduce legginess. Good air circulation is also important.
Keep the water reservoir full to keep the capillary mat moist at all times. Check the water level regularly and add water through the notched end of the platform. If the mat dries out, thoroughly moisten it to re-establish the capillary action. If the soil seems too wet, empty the reservoir for a couple of days so the soil can dry out.
To keep roots from growing into the capillary mat, lift the cell pack off the mat once or twice a week.
To ensure a constant supply of nutrients for your seedlings, a diluted solution of liquid fertilizer may be added to the water reservoir.
Your seedlings should be hardened off slowly before they’re planted in the garden. Do this by placing them outside for a few hours each day for 1 to 2 weeks, gradually increasing exposure to sunlight and wind.
Once you have transplanted your seedlings into the garden, you may want to plant a second crop of seeds and place the seedstarter directly outdoors. The seeds will germinate quickly in the springtime sun and can then be transplanted into the garden.
Wash all parts of the seedstarter with warm water to remove soil and other debris from surfaces. Soak the capillary mat in a diluted bleach solution and rinse in clean water. (All plastic parts of the seedstarter are top-shelf dishwasher-safe.) Store the unit away from sunlight when not in use.
