Description: This is our propagator for starting seedlings in the basement.
We chose GORM shelves that make a total width of just over 4′, since standard shop lights are 4′ wide. After assembling the shelves, we added some screw in cup hooks to hang the shop lights from. The lights can be raised as the plants grow.
We put heat mats on one of the shelves since some plants like to be warm. The power for heat mats and lights is fed through a power squid which is taped under the middle shelf to keep it under control. We also put some plastic sheeting on the shelves to reduce the chance of water leaking through.
