Starting seeds in rock wool cubes for your Tower Garden vertical garden? Once the seeds have sprouted, I use a weak solution of Tower Garden Mineral Blend. I use a solution that is about 25% of the normal ratio. Once the seedlings are put into your vertical garden use a 50% solution of Tower Garden Mineral Blend for about the first month and then progress to the full solution as your plants become bigger. This works well when you are starting with all new plants as you would do in the spring.
I also use normal strength Tower Garden Mineral Blend on my soil-plant starts that will be transplanted into my traditional soil garden. Tower Tonic Mineral Blend is the best all-around fertilizer, and it’s all-natural! “But what about the cost?” you ask. Just $60.00 of Mineral Blend could easily last all summer!
