GREEN HOUSE FEEDING – SIMPLE FEED SCHEDULE
The feed schedule below can be used without monitoring pH and EC values; however, we do recommend to always measure pH and EC for best results. Tap water hardness should also be taken into consideration.
When using hard water and nutrient rich soil, one product (Short Flowering, Hybrids or Long Flowering) can be used from start to finish, making the GHF feeding line very cost efficient.
It is possible to use a combination of GHF base nutrients and Booster PK+
If a range of values is mentioned below (e.g. 5-7g/10L), it means that the first value is used to start with and should be increased every week until the final value is reached.
