Superthrive Fertiliser

Size: 120ml


Superthrive has been used in the horticulture and agriculture industry since 1940 and is a renowned nontoxic vitamin and amino acid growth promoter from the USA.

It can be used on a daily basis to promote and boost growth but it is also a brilliant stress reliever for your plants anytime they are suffering (for example from heat stress and over fertilisation).

Superthrive is a vitamin-hormone liquid concentrate, containing .09% vitamin B1 and .048% of the hormone 1-Napthyl acetic acid (NAA). It does not contain any NPK macro-nutrient fertiliser. It should be used as an additive alongside a normal fertilisation program with other plant nutrient products, and not as a standalone fertilisation product. It works directly on the roots to encourage robust and healthy plant growth and to revive plants that have had a hard time, but Superthrive is also commonly used to reduce the stress caused after plants are transplanted.

Since it is nontoxic, it is safe to use on all edible plants and many growers also use it as foliar spray to give their plants an extra boost (spray on the underside of leaves for the best results). It is designed for use throughout the entire plant growth cycle and studies have shown it to be effective in both the vegetative and productive flowering / fruiting stages.

How to use

As a guide Superthrive should be used at a rate of one drop for every four litres of water. However, this does depend on the intended purpose and the types of plants you are cultivating. You can find out more about the guideline dosages on the manufacturers website.

Our Opinion

We personally believe that Superthrive is best utilised as a one-off treatment for stressed out plants, whether that’s stress from transplanting or stress from other factors such as heat or over fertilisation. For these purposes there really is no better product on the market. However, for general daily use as a growth promoter you’ll be better off going for a product like Hesi Supervit.


Superthrive FAQ’s:

When is it best to use Superthrive?

We recommend using Superthrive as a treatment to revive plants and restore health after they have suffered from any cause of stress. It can also be used effectively as a growth promoter and booster, but we feel that other specific growth promoting products such as Hesi Supervit work better for this purpose.

Is it safe to use on all plants?

Yes, Superthrive is a nontoxic product that can be used on any type of plant, including edibles such as tomato or lettuce plants.

Can it be used in hydroponics systems?

Absolutely, just make sure you stick to the recommended dosage ratio of one drop per four litres of nutrient solution when scaling up to larger volumes. It can also be used with Aquaponics and can even help promote algae growth.

Is this a standalone nutrient solution?

No, if you choose to use Superthrive as a growth promoter then you should use it alongside a regular fertilisation program that includes all of the macro nutrients and micro nutrients plants need to survive and thrive.

How often should I use Superthrive?

This really depends on your needs. It can be used daily, weekly, monthly, or quarterly. One thing to note is that it is hard to use too much Superthrive, but over use will just result in a waste of money as only a little is needed. If you do use too much, you can easily rectify the situation by diluting your nutrient solution with more water.

Can I premix a solution?

For the best results both us and the manufacturer recommend you avoiding premixing the solution and instead create a mix on the day you intend to use it.
