Commonly Asked Questions

Q. I have recently changed to growing under LED lights. Does my nutrient strength
need to be stronger due to the increased light output that LEDs provide?

A. Possibly. High intensity LED rooms and/or CO2 rooms can use up to 30% higher EC than listed in our feed programs, however every phenotype will have slightly different requirements. Caution should always be used if exceeding the recommended EC levels

Q. I am starting the Easy Feeding Program (1, 2, 3, 4) but I don’t have a separate
grow and bloom nutrient. Am I missing something?

A. You’re not missing anything. Dual Fuel 1 & 2 is used for both the grow and bloom stages. Massive is used as your dedicated bloom booster and will be added in the bloom period for the extra Phosphorus & Potassium your flowering plants require.

Q. I am starting the Professional Feeding Program. What part should I add first?

A. Always add Plant Guard first. Allow to diffuse in the nutrient tank before adding any other nutrients or additives. Adding Plant Guard second will immediately turn your nutrient tank cloudy as it falls out of solution. If this happens dump the affected tank and start again, but this time with Plant Guard first.

Q. There are two bloom boosters – Massive and PK Spike. What is the difference?

A. PK spike is a mineral based Bloom Booster. Massive is a mineral/organic blend. Each independently delivers the full amount of Phosphorus & Potassium that your plants need. Use one or the other depending on your growing method.

Q. Why do you sell two different bloom boosters? It’s confusing.

A. Some licensed producers use UV sterilisation to deliberately target and kill
organic matter. Sterile facilities use mineral based fertilisers such as PK Spike.

Q. What are the advantages of organic additives like Massive?

A. Massive is a mineral and organic blend. Organically minded growers seek the advantage of the symbiotic relationships between plants and organics that nature provides. Advantages include naturally occurring growth enhancers, Gibberellins, amino acids and enzymes.

Q. Your feed chart only shows nutrient strengths in EC. What should I do if I have a ppm, TDS or CF meter?

A. All of these meter readings are just a measure of nutrient concentration. Use the conversion chart on this page to align your meter reading with the recommended EC of our nutrient feeding programs.
