In a standard hydroponic system, production plants go through a period of vegetative growth that lasts 4 weeks, followed by a period of flowering growth that lasts 8 – 10 weeks. Total grow time for production plants is approximately 12-14 weeks.
There are 14 essential minerals in fertilizers that plants require for life. Macro nutrients are used by plants in the highest amounts. Micro nutrients are used in smaller amounts but are still required for life.
Tap water by itself is not enough to feed your plants. Tap water contains some native minerals but not enough, or all the required minerals. Fertilizer supplements containing all 14 essential minerals must be added to tap water to create a feeding solution.
Hydroponic plants require a very precise application of fertilizer. Dosages vary from week to week, supplying plants ideal nutrition for their stage of growth, while avoiding excesses that cause toxifying salt buildups in the grow media.
The multi-step Dr. Seeds Professional Hydroponics System is designed to prevent a toxic build up of minerals and optimize growth. For example, the system delivers more phosphorus during the 1st week of growth when plants can use it to support root strike, and during the 4th week of growth when plants use it to initiate budding. During weeks 2 and 3 phosphorus is applied less because at these times extra phosphorus won’t help your plants and excesses of it will block other beneficial nutrients from being absorbed. The nutrient ratios in the Dr. Seeds Professional Hydroponics System are proportioned perfectly for growing cannabis in hydroponics.
The amount of calcium and magnesium that needs to be added to the feeding solution depends on the starting state of the tap water. Tap water that is very hard contains calcium and magnesium already and doesn’t need as much extra added to it. R/O water or tap water that is very soft needs more calcium and magnesium added to it.
The Dr. Seeds Professional Hydroponics System offers optimal nutrition and works well for many cannabis strains. There are two kits available, one for R/O water and one for tap water. The kit for R/O water contains a full supplement of calcium and magnesium. The kit for tap water contains less calcium and magnesium because average tap water contains native calcium and magnesium already and doesn’t need as much extra added by fertilizer.
