Except as provided in this warranty, neither Grower’s Choice makes any representation or warranty of any kind, express, implied or statutory, as to any matter whatsoever, including without limitation merchantability, fitness for a particular purpose, non-infringement or otherwise. Grower’s Choice hereby disclaim any such warranty. Without limiting the foregoing, Grower’s Choice do not make and shall not be deemed to have made any warranty as a result of any testing, sampling, or similar analysis that either may perform.

Grower’s Choice shall not under any circumstances be responsible for any loss or damage, indirect, special, ordinary, exemplary, consequential or otherwise, arising out of the purchase or use of the lamps, except as expressly provided in this warranty.
