We are the only retailer in Canada that actually grows a large proportion of our plants in house. Most of our plants start off in Tissue culture. Some are sold to the general public in tissue culture form while others are then moved into pots and go straight into our aquarium nursery system. As a result of this, all of our plants in our "PlantGuy Wholesale Nursery" section are in submerged form and will be easily adapted to your aquarium when you receive them.
If you're wondering why the prices of these plants are so low, the reason is the plants aren't going through 2 levels of distribution before hitting the retail market.
