Jack takes you throught the steps of creating a plant light. Begin with a large sterolight container, all thread,bolts, nuts and washers, and a power strip with tie wraps to hold it togethers You'll use flourescent lights and two pieces of plywood. Two nuts are used to hold this together and its painted white. The plywood reinforces the lid because it isn't very sturdy. This allows the seeds to grow faster because they're in a controlled temperature. The sterolight is waterproof so you don't have to worry about leakage. The lights and the plywood are placed inside the lid and you've created a safe environment for your seedlings.
