Photosynthesis is the process of converting carbon dioxide into sugar under light, which is needed for plant growth. However, plants do not photosynthesize efficiently; only 2-4% of light is converted into sugar. Harvast is sprayed onto leaves once a week to enhance photosynthesis. It helps plants to photosynthesize more efficiently by up to 100%. This leads to faster and bigger growth. It is not a fertilizer, but it works well with all types of fertilizers.

Spray Harvast onto leaves once a week, preferably after watering.

No. Harvast is ready to use. Do not dilute.

No, Harvast is not a fertilizer. It is a photosynthesis enhancer; a new technology developed in Universiti Putra Malaysia. It is compatible to be used with all types of fertilizers and pesticides.

Harvast can be used for ALL types of plants because all plants photosynthesize. It can be used for ornamental plants and all types of vegetables.
(The efficiency will depend on the type of plants. C4 plants benefit more from Harvast.) 

Yes, Harvast is safe to be used indoors, even around children and pets. It can even be used on vegetables for consumption. It does not contain any harsh chemicals. The active ingredient is organic based.

Harvast is not a fertilizer. If the medium is nutrient-rich, using Harvast alone can boost plant growth. Using Harvast reduces the need to use excessive fertilizers which harm the environment.

Harvast does not cause any adverse reactions unless the plant is severely deficient in water and/or nutrients. Ensure your plants are well hydrated (without over watering) and have access to sunlight/grow light.

Harvast can be sprayed at anytime of the day, once a week, preferably after watering.

Harvast+ is a more advanced photosynthesis enhancer, specifically formulated for ornamental plants, especially aroids. Harvast+ should be applied onto leaves, once a week, preferable after watering.
