Really great selection, and I must say I was surprised by the pricing because the plant hobby can get a little bit expensive and I think a lot of places capitalize on people not knowing where to get specialty mediums and fertilizers. The prices were great here, the staff was also very friendly and knowledgeable which was a really nice change, I find that most staff at garden centres or nurseries don’t usually have answers or much knowledge about the products they are selling which was totally not the case here. Definitely would recommend this place to everyone!

Hands down the best hydroponic shop I’ve been too. Everyone who works here is very friendly and knowledgeable about growing cannabis and which products suit you. Any time I have a problem with my grow set up and need something new they’re there to help me with any questions I have. I’ve bought many products from here and drop in every week. Truly love what you guys do here. Keep up the great work For people having a hard time finding the place it’s in the coffees time plaza just out back. The entrance is just to the left of the coffee time. -Mikey
