This chart, like all nutrient charts, should be treated as a guide, not an exact plan. We are confident this chart is accurate however tap water from area to area differs.
With passive soil systems, to get it right, you must learn to read your tank and your plants. Firstly, do NOT grow blindly, you MUST have an EC meter and a pH meter no matter what if you wish to be successful!
We recommend adding the pH Water Conditioner to your water first. Mix it in well and leave for 10 minutes, then you can dose in your additives according to the chart depending on which WEEK you are dosing for. You then add our All-in-One nutrient. Although we have given you the dosage on our chart, it is strongly recommended to add the base nutrient gradually and check the EC with a calibrated EC meter until you reach the desired EC level. Once you have got to this stage and allowed everything to mix in for another 10 minutes or so, check the pH value of the solution again, you will find you may need to add pH down at the end. Do not exceed 0.75ml per litre of the water conditioner, as primarily, this is not a pH down. If the desired pH is not met, use pH down to achieve desired pH level. Do not keep adding water conditioner to lower the pH. A pH level of 6.0 - 6.5 is the ideal range to be in.
Before every application the bottles should be shaken vigorously, and the same principle employed in the tank, ie. a decent recirculating pump or circulation pump should be employed.
Due to the varying mediums people employ with this technique, we have dialled back the strength of nutrients used. The chart opposite applies if you are running a predominantly soil based medium. If you are using a purely inert medium in these systems like perlite then you can increase the food levels up to that of the soil run to waste chart. i.e double of this one. Remember less is best, you can increase the food levels as the plant calls for it.
From time to time it would be good practice to top feed and collect the run off so as to compare what was fed. With this knowledge you can make said alterations. i.e if you are feeding the plants an ec of 1 and a ph of 6 and the run off comes out at ec of 1.2 and ph of 6.5, then adjust the tank to ec of 0.8 and ph of 5.5. Do this until the run off matches the feed. Obviously the same applies in reverse if the opposite happens.
This will stop the potential of any type of nutrient build-up or lock out, and will ensure the correct application of this range.
The chart includes a starting background tap water EC reading of 0.4
