Rockwool:
Many growers like to use the cubes for seed germination and
for rooting cuttings. This seems to be the easiest to use. Many growers
claim that rockwool should be pre soaked for 24 hrs in water with a pH
level of 5.6 (7.0 for soil grows). This is to stabilize the pH level of the
rockwool.
How to make up nutrient solutions:
Always follow the very simple instructions on the products.
All you need is a container to make up the nutrients in and the
nutrients themselves. Each of the packs should have A, B, and C
written on them. The mixture is usually 3.5mls of A and B and C per
liter of water. This is called a 100% strength mixture if you follow the
guidelines as stated exactly on the label.
Hydroponics pH:
After you have mixed up your nutrient solution you will want
to take a pH reading of it. If you have any problems, just like in soil
growing, you will need to adjust your pH level. Now, you do not use
the same method to adjust pH levels as described in the soil chapter.
For hydroponics you need to buy a pH Up and pH Down adjusting
