Why Grow Inside?

There are several great reasons to start this amazing hobby, self sustainability for one. With the rising cost of everything we consume, growing your own can save a lot of money. Another reason is to enjoy a living garden year round. In the middle of winter when it is freezing cold, there is nothing better than walking into a warm grow room with green plants, alive and producing fruit. This is one hobby that constantly pays you back.

Two green thumbs way way up for these guys! Everytime I have a problem in my garden, they have the solution. They haven’t let me down yet. Thanks Sam and Andy! Also thanks for suggesting I switch to the house and garden nutrient line, very impressed! When I decide to expand, you guys will continue getting my business!

Hands down the #1 hydroponics shop in the Twin Ports area.  Great atmosphere, with excellent staff who know their products and go beyond the extra mile to be of any assistance. The willingness they have to make a good impression on the community, along with the  deals on hand are outstanding!!  See for yourselves if you have any doubt.  I wouldn’t shop anywhere else for any garden growing /health needs after shopping at their establishment.  Plus I like their T.V. commercials.
