A Gardener's Supply innovation!
Start with the Stack-n-Grow Garden Starter Kit (base unit). Then stack up to three Add-On units. Each unit has two 3' high-output, full-spectrum T5 bulbs that are spaced for optimum light coverage. High-tech reflectors direct 58% more light down onto plants for healthier growth and less glare.
Important: When stacking units, we recommend preventing water from dripping from upper shelves onto the light fixtures below by using our Small Trays (32-709), drip trays or saucers on each shelf.
