Greenstar Plant Products, Inc is an international producer of premium horticultural products and solutions for domestic and commercial use. Only the finest quality horticultural grade nutrients, free of chemical contamination, are used to create our brands. All raw materials are analyzed prior to use to ensure they are free of any toxic substances, such as lead, mercury, arsenic and high-salt content - typically found in low-grade fertilizers.
Greenstar brands are safer for the environment than what is widely available on the market today.

Earth Safe™
Earth Safe™ fertilizers offer a broad selection for the more specific needs of the home gardener. This line is organic and organic-based for the discriminating gardener that wants only the best for their plants. Larger pack sizes for those with bigger yards and gardens result in fewer trips to the garden centre to buy plant nutrients. This line also includes a non-selective weed killer made of natural food grade vinegar. Elimaweed is biodegradable and does not accumulate in the soil.
Comprised of both liquid and granular fertilizers, the Earth Safe line provides the right nutrients for all of your growing needs.

Grotek Life™
Grotek Life™ is an organic and organic-based line of fertilizers for all your indoor and outdoor plants. This line was designed to simplify your gardening program and provide optimum results without having any harmful effects on your plants or the environment. Made of high-quality fermented horticultural grade ingredients, Grotek Life has a low salt content and it is harder to over fertilize as the nutrients are available in the right concentrations. Low N-P-K numbers do not mean that your plants will be undernourished. Your plants can only use a small portion of the nutrients at once, so feeding with a 20-20-20 fertilizer means that most of those nutrients are flushed into the ground water. This results in a waste of money and contributes to the pollution of our waterways. Organic products also produce stronger plants that are more resistant to disease and pest attacks reducing the amount of pesticides used. These highly concentrated products will go a long way and are easy to use.

Grotek™ Science for Plants
Plant nutrition is more than just the N-P-K (macro-nutrients). There are also micro-nutrients such as calcium, magnesium and others, with nutritional requirements varying depending on what plant you are growing. Just like humans, plants suffer deficiencies caused by their environmental conditions and nutritional requirements. Plant supplements help to improve these deficiencies for a stronger more vigorous plant. Recognizing a need for high-quality supplements, Grotek™ was launched more than 10 years ago. VitaMax, the first product to hit the market under the Grotek brand, continues to be a strong leader in the market today. The Grotek brand has since blossomed into a complete line of base nutrients and supplements to meet specific growing needs. Serving municipalities, greenhouses and farmers globally, Grotek will continue to use Science for Plants to bring the best products to your plants.
