Our system has so far shown to be very effective. Our Strawberry plants are now starting to fill out and the leaves are taking on some shape. When we checked on them on April 1st, we noticed that the tops of the rock wool were covered in what appeared to be green moss, and had also noticed that the water was becoming very dirty. Strawberry hydroponic systems need to have the water and nutrients changed twice a month and we changed ours for the first time since planting the seeds.
Before we changed the water, we checked the pH of our system and the temperature. Our pH was 6.9 and the system was kept at 70 degrees. We then changed the nutrients and cleaned out the container that held the water. After adding in the new water and nutrients are pH was a little high at 7.2 and added half a teaspoon of pH Down to bring the pH back down to 5.9.
We hope to see within the next two weeks or so the roots of the plants to branch out more, and for the plant itself to grow larger and hopefully starting budding.
You guys seem to be doing a great job keeping track of your plants & caring for them!! I did not realize how different plant’s nutrition needed to be depending on the type and I am really excited to see how well yours grow!!
