Question 1

Why do you guys have so many products?

Accepted Answer

With growers across the globe growing different plants in different ways in different environments with different requirements, it’s important to have a diverse range to support all of that success! We recommend you research your needs and then find the right products to support your crop. We can help with suggestions if you are unsure. Our team is here to give you confidence and results with our range of options for your garden.

Question 2

Can I mix Grotek products with other brands of fertilizer?

Accepted Answer

We encourage all gardeners to experiment with their own recipes for success. But caution is always a part of making a new recipe. It’s important to consider all products and do some testing to check for compatibility. A good start is to understand the purpose and hopefully ingredients of all products. Try to avoid overlapping function because this can be too much of a good thing.

Question 3

Can your products “burn” my plants?

Accepted Answer

All fertilizers have the potential to harm plants when over applied. It’s important to follow directions for use as a good guideline. And remember, more is not always better. Make sure you observe your plants visually as much as possible. Corrections can be made quickly if you are monitoring your crop properly.

Question 8

Do I need to use all of your products to be successful?

Accepted Answer

NO! In fact we don’t recommend you try and use all of our products together. Our range has a lot of choice. Our products are targeted to plant stages, different requirements and different gardening styles. If you need some help check in with our team for support!

Question 9

How should I store my products?

Accepted Answer

Keep products sealed in the original container in a cool, dry location, out of direct sunlight.  This will help extend shelf life and reduce changes to the product over time.

Question 10

I found some old product is it still good to use?

Accepted Answer

Our products are stable over long periods of time to make sure growers get the best results for as long as possible. Most of our best before dates are around 3 years with the exception of biology. Most products can be used after that date but there will be a drift in the effectiveness of the product the longer it moves beyond 3 years. Anything over 3 years old should be spot tested on a few plants before use on the entire crop to make sure the efficacy is still there.
