Canada's Favorite Hydroponic Supply Store
Starting at CA$9.19
Canadian Garden Insider says.....
These strong buckets are used for many different applications in gardening. Many growers use them with a lid and mesh basket to make a hydroponic bucket system. Other growers use them for hauling soil or pre-mixing nutrients. They are handy to have around if you want to mix up a just small batch of plant food or additives.
For hydroponic applications, add on the black plastic bucket lid and you can cut a hole in the top to the size of the mesh basket that you need.
