Frequently Asked Questions

Which Plagron fertilizer to choose for an indoor soil grow: Terra Grow or Alga Grow?

Terra Grow is more concentrated (NPK 5-1-4) and acts faster, ideal for short cycles or if you want to push growth. Alga Grow (NPK 4-2-4) is gentler, 100% organic, perfect for longer growth periods or if you prioritize the final taste. In enriched soil like Light Mix, Alga Grow is more than sufficient. In poor soil, Terra Grow will be more effective.

How to accurately dose Terra Grow and Bloom according to the Plagron chart to avoid over-dosing?

The Plagron chart indicates 1-2ml/L for Terra Grow during growth, 2-4ml/L for Terra Bloom during flowering. Always start with the minimum dosage and monitor the EC: 1.2-1.4 during growth, 1.6-2.0 during flowering. If leaves yellow quickly or the EC exceeds 2.2, halve the dose. Plagron is concentrated, it's better to under-dose than to burn the roots.

What's the difference between Green Sensation and Sugar Royal to boost flowering with Plagron?

Green Sensation (PK 0-9-10) is a late-flowering stimulator that increases resin production and density. Sugar Royal is more of a taste enhancer based on molasses that feeds beneficial bacteria. Green Sensation is used during the last 4 weeks, Sugar Royal can be used from the 3rd week of flowering. You can combine both without any problem.

Should Power Roots be mixed at the start and how to integrate it into a Plagron grow setup?

Power Roots is essential during the first 3 weeks to develop the root system. Dose at 1ml/L from transplanting and continue until the stretch. Mix it with Terra Grow or Alga Grow in the same nutrient solution, no compatibility issues. The humic acid it contains improves nutrient absorption by 20-30%, which is measurable in plant vigor.

How to maintain pH and EC with Plagron terra fertilizers to prevent deficiencies?

Plagron fertilizers are buffered but still monitor: pH between 6.0 and 6.8 in soil, EC between 1.2-2.0 depending on the phase. If the pH rises above 7.0, add a few drops of pH Down. If the EC climbs too fast, dilute your solution. Plagron contains chelates that remain assimilable even with a slightly off pH, but stay within the range to avoid iron or magnesium lockouts.
