Keep your Tower Garden nutrient solution in the proper pH range with the Tower Garden pH Kit. The kit makes it easy to test your reservoir water and adjust the pH when needed so your plants can properly take up nutrients.

For Tower Garden, the nutrient solution should generally be maintained between pH 5.5 and 6.5. Test your water, then use the included pH+ or pH- solution to raise or lower the pH as needed.

A pH Kit is included with the purchase of a Tower Garden FLEX or Tower Garden HOME. This replacement kit is available when you need additional testing solution or pH adjusters.

Need more of just one adjuster? Shop the Tower Garden pH Lower Kit or Tower Garden pH Raise Kit.
