Try Vancouver-based easy-to-use indoor plant food made form wild harvested Canadian kelp. It won't cause salt build up and can be used year-round for happy healthy plants.
Kelpy is food for plants that helps promote new growth, bigger leaves, more vibrant colours and builds resistance to pests.
The kelp is harvested from the frigid coastal waters of Northern Vancouver Island where it grows more than 2 feet a day from the rich mineral glacial outflow that feeds it and is cold processed (never heated) to keep all of the vitamins and nutrients intact.
A little goes a long way. 1 bottle makes 50L.
Giant kelp (macrocystis integrifolia)
Directions: Follow the regular watering schedule for your plants. Mix 1 tsp of Kelpy with 1 ltr of water and feed those beautiful plants. Use every two weeks year-round. Food for plants, not for people. Not for human consumption.
