Nutrient Requirements
Add premixed water soluble organic or conventional fertilizers and nutrients directly to the Hydro
Reservoir. Adding fertilizer at the time of planting can be delayed if your growing media is already
infused with fertilizer.
Note: You may find that you are using less nutrients with our Hybrid Grow Systems.
Why? Because Octopot Hybrid Grow Systems are closed systems that never waste fertilizer or
nutrients from washout or run off.
THE RULE FOR OCTOPOT IS: LESS IS MORE
pH & PPM
pH performs an enormous role in PPM concentrations. PPM can be spot on but if pH is off, PPM is rendered
meaningless because the plants can’t absorb the nutrients they need.
Learning to adjust PPM and pH can be challenging. As you adjust one, the other will react. As a rule of
thumb, it is more important for pH levels to be correct than PPM levels.
The use of a TDS or EC meter to measure PPM is a precise way of ensuring that your plants receive exactly
the right amount of nutrients.
Note: EC and TDS water meters fit into the Octopot reservoir hole, making it simple to measure and control feeding!

Harvest
Throughout the plant’s life cycle, cannabis plants have distinct nutritional needs.
There is an optimal level of PPM & pH for each phase of development.
These are only guidelines; please observe your plants and research your strain for more detail specific guidance.
