The plants are developing VERY well and grow with a HEALTHY GREEN COLOR. The BIO TABS nutrients are VERY CONVENIENT, since I only have to give PURE TAP-WATER to the plants. The nutrients are already in the soil and work for the whole cycle, all the plants need is watering. Normally I would use ph-minus to get my ph-value to 6,0 , because the tap-water is too high, but with BIO-TABS nutrients I do NOT NEED TO DO THIS! They are SELF-REGULATING, which means the bacteria in the soil change the ph-value they need! I LOVE THEM!
