What is The Sunmaster 600W 10k MH Finishing Bulb?

Sunmaster 600W 10k Metal Halide Finishing Bulbs are intended to use for the final 2-weeks of flowering to set flowers and fruits. The finishing bulb offers UV, the violet-blue end of the light spectrum. They give the perfect light spectrum for the final stages of the flowering cycle. The bulbs operate to help ripen flowers and fruits grown indoors.

Who Are SunMaster?

Sunmaster designs and manufactures a complete line of metal halide lamps with spectral output tailored to specific plant growth needs.

The range of Sunmaster lamps promote higher levels of photosynthesis and are customised for various growth cycle stages. this bulb produces higher levels of the essential far red, UV light that simulates the late summer/early autumn sun light, where plants will naturally mature and set flowers/fruits. Supplementary UV light is perfect for the final stages of a growth cycle.

How Does the Sunmaster 600W 10k MH Finishing Bulb Work?

The Sunmaster FINISH bulbs are rich in UV light, the perfect light spectrum for the final flowering stage of a flowering plant's lifecycle. Using a UV specific finishing bulb helps to increase essential oil production. This works to improve the aroma, flavours, and stability of the final product. The bulbs help to ripen fruits, and offer a long life, with a high output.

The Finishing bulb by Sunmaster works by stimulating the plants' response against harmful rays and sunburn. The plant has its own inbuilt sunscreen, which is known as essential oils, produced as resin and oils on its surface. UV light radiation increases the production of essential oils.

Different Bulbs For Different Parts of the Plant's Lifecycle

Most indoor gardeners know about swapping out their bulbs as their plants transition from vegetative to flowering growth. They know the importance of offering the right kind of light for their plant's stage of growth. Put simply, plants have different light spectrum requirements depending on their stage of growth.

How Do I Use Sunmaster 600W 10k MH Finishing Bulbs?

To finish your plants and set the flowers/fruits: swap your HPS bulb out for the Sunmaster 600W 10k MH Finishing Bulb in the last 2-weeks of the flowering stage of growth. Doing this, you'll benefit from the extra blue, violet and UV light spectrum this finishing bulb offers. The UV-end light helps to increase the flavour and taste by increasing essential oil production in flowers/fruits, with higher terpene and sugar content.

Finishing bulbs work with standard 240V 600W digital and magnetic ballasts. Never use finishing bulbs, or metal halide lamps with the overdrive function on the ballast, as it could lead to the bulb exploding.

Garden tip: Use the finishing bulb alongside a flower booster. Flowering Boosters, such as GrowDog Botanical Boost provide your plant with extra nutrients that the plant uses to produce additional essential oils, as encouraged by the finishing bulb.
