Once you have the Stack-n-Grow Lights Base Unit, you can place up to 2 Add-On Units on top, to easily expand your growing space, up to 3 levels. (Note: This Add-On requires a Base Unit to operate properly.) Each Stack-n-Grow Light unit is equipped with two full-spectrum T5 fluorescent bulbs that are spaced for optimum light coverage, and super easy to raise or lower. High-tech reflectors direct light down onto plants for healthier growth and less glare.

At only 7 lbs., each Stack-n-Grow unit is super lightweight — but sturdy enough to hold up to 110 lbs. Add-On Units fit easily onto the base unit, assemble quickly without tools, and store compactly when not in-use. Wall brackets are included for added stability. Height Extenders are also available to increase headroom and vertical growing space between tiers. 

The modular Stack-n-Grow Lights System is as easy as 1-2-3!

1. Start with 1 tier: Stack-n-Grow Lights – Base Unit
2. Or jump right to 2 tiers: Stack-n-Grow Lights – 2-Tier System
3. Add more tiers, up to 3 levels: Stack-n-Grow Lights – Add-On Unit

Important: When stacking units, prevent water from dripping from upper shelves onto the light fixtures below by placing our Small Boot Trays underneath, or use other drip trays or saucers on each shelf.
