A Note on Extension Kits & Grow Lights 🌿💡
While all Tower Garden Extension Kits fit on both the HOME and the FLEX, we generally recommend adding them to the FLEX only. The HOME model has a smaller, narrower base, and adding too much height can make it unstable—especially if it’s placed outside on a windy day.
When it comes to grow lights, keep in mind they can be used with one extension, but that’s right on the limit. For best results, grow lights are designed to fit perfectly on a FLEX or a HOME without extensions. This ensures even coverage and stability while keeping your crops thriving indoors.
Which Extension Kit Should You Choose? 🤔
✅ Extension Kit → If you just want a little more space for your favorite crops.
✅ Baby Green Extension Kit → If you love salads and want maximum baby greens and small herbs.
✅ Extension Kit Combo → If you want a mix of full-size crops and baby greens/herbs for variety.
No matter which you choose, all extension kits are easy to install and designed to keep your Tower Garden growing strong.
