+ | ===== Special handling for heat-loving plants ===== | ||
+ | ==== Heat mat setting ==== | ||
+ | |||
+ | When I germinate seeds for heat-loving plants like peppers and tomatoes, I set the heat mat controller at a suitable level, generally 75 degrees. | ||
+ | |||
+ | <note tip>The temperature setting on the heat mat controller is a maximum, not an actual temperature in the tray under all conditions. When the ambient temperature is considerably lower than the set temperature, | ||

+ | ==== Grow lights ==== | ||
+ | |||
+ | These warm-weather plants like warmth as they grow in the greenhouse. Grow lights set at a suitable distance (about 7 inches) from the seedlings provide an acceptable amount of warmth. | ||
+ | |||
+ | ==== Re-potting ==== | ||
+ | |||
+ | Shortly after a seedling has two "true leaves" | ||
+ | |||
+ | <note tip> | ||
+ | |||
+ | ==== Irrigation ==== | ||
+ | |||
+ | The more true leaves that a seedling develops the more moisture that they transpire from the tray to the environment. So the more mature seedlings get, the more care they require in managing irrigation. | ||
+ | |||
+ | === Irrigation temperature === | ||
+ | |||
+ | For heat-loving plants, which really love extra attention, I provide moisture with water at the temperature of the tray- not cool water from the faucet. An unexpected dose of cold water can send the seedlings into shock, which slows their growth and reduces their robustness. | ||
+ | |||
+ | === Irrigation solution === | ||
+ | |||
+ | To provide nutrients to the growing plants in addition to what is in the potting mix I irrigate with (about) a 1% mixture of water with fish fertilizer and liquid seaweed. | ||
+ | |||
+ | {{ : | ||
+ | |||
+ | * 3 teaspoons of fish fertilizer | ||
+ | * 3 teaspoons of liquid seaweed | ||
+ | |||
+ | I pour this solution into the tray, allowing the potting medium to soak it up and percolate it to the plant' | ||
+ | |||
+ | <note important> | ||
+ | |||
+ | ==== Fertigation ==== | ||
+ | |||
+ | Often I use the liquid irrigation solution to provide additional nutrients by spraying it directly on the leaves of plants after transplanting. |
