This year I purchased a grow tent. Basically, this acts as an inside greenhouse. Reason for this was to give the seedlings a happy, warm, environment to grow, so that when it is time to plant outdoors, they are well on their way to being strong, and hearty.
The tent is on for 24 hours a day and the heat lamps inside are programmed to heat up to approximately 78-80 degrees for 14 hours a day. Once the heat lamps are off the tent remains 70 degrees.
I started the seedlings the third week in March. A little later than I usually do. Below are some pictures of the crops from the very beginning in small containers, to being transplanted into larger containers when the roots have been well established.
My hope is that the plants will continue to thrive in the tent so that when they get planted outdoors, they will be large enough to produce vegetables earlier than in previous years allowing for a longer harvest. Wish me luck!
