Sentinel

Global Product Solutions - makers of Sentinel Environmental Controllers.

Global Product Solutions engineers have been designing and manufacturing horticultural products since 1997. Their mission today is the same as when they first started:

To produce the absolute best products…with competitive prices.
  • Without sacrificing quality, Sentinel will always choose high quality components over inferior “economy” parts.
  • Sentinel continues to make concentrated efforts to design products that give gardeners the solutions they want AND need.
  • Product designs are “user friendly” 
That is why Global Product Solutions has decided to take the lead to change the face of an industry. Hydroponics has been around for thousands of years. But only in recent years, has the full potential of hydroponics began to be recognized. This is primarily due to technology, Sentinel is taking advantage of the huge advances in computer technology and software to design some truly revolutionary products.
