How to read the chart
Values are ml of product per litre of nutrient solution. Add products one at a time, mixing well after each — VitaSilica always first.
Feeding chart
The Vitaponix feeding chart.
Every dose in the Vitaponix line in ml per litre, week by week: vegetative growth and flowering. The same style of chart you know from General Hydroponics and Biobizz — built on the biological language of our eight products.
Water and pH
The chart is calibrated for reverse-osmosis (RO) water. After mixing everything, adjust pH to between 5.8 and 6.2 before irrigating.
Reference EC
The program starts at 1.4 EC when rooting a cutting and rises step by step to 2.2 EC in full flower. No EC pen? Follow the ml doses — they are the fallback. Always measure before correcting.
Vegetative growth
From roots to structure: VitaRoot drives the root system, VitaBase builds growth, VitaSilica reinforces tissue from day one.

Flowering
The baton passes to VitaBulk for floral mass, with VitaBud and VitaSweet for density and aromatics, and VitaFinish in the last two weeks for the finish.

Practical tips
- Change the solution completely every 7–10 days, even in recirculating systems.
- If leaf tips burn, drop the total dose by 10–15% before changing anything else.
- Under very intense lighting plants drink more: check the reservoir level every day.
- In the final two weeks VitaFinish replaces VitaCal and VitaSweet: it's the finishing phase, not a push.
- Shorter or longer cycle? The calculator generates the program for your exact number of weeks.
- These doses are a proven starting point: watch your plants and adjust gradually.
