Alternative Nutrient Solution for Tower Garden
I am an avid ground gardener but I wanted a Tower Garden for my porch. One of the main reasons why I bought this tower is that I was told that I could grow some vegetables "out of season". In my location Swiss chard is a winter vegetable but it is growing well in the tower. As for other veggies, I'm not so impressed.
Now that I have this Tower Garden, I'm realizing that the nutrient solutions, A & B that the TowerGarden website sells is quite expensive. There must be a better way.
My question is - How do I learn about using a different "brand" of nutrient solutions? And where is the best place to purchase them? As for water, I have access to both city water and well water. Which is better? City water, pH is 7.6 and well water, pH is 7.8. (I only use city water after it has sat in buckets for a couple of days.)
Hydroponics is a new way of gardening for me and I would like to learn more about it.
