Ultimate Yield Recipe

BloomBoss’s Ultimate Yield Recipe Ingredients

For your garden to thrive, plants need the right balance of these 8 basic “ingredients”:

1. Light

2. Air Flow/CO2

3. Growing medium

4. Temperature

5. Humidity

6. Nutrients

7. Water

8. Patience!


Lighting is the single most important factor in the success of your garden.

Our TrueSun Smart Spectrum was developed by indoor growers over many years of careful experimentation and testing to provide you with a true replacement for the sun.

In the spring the Sun’s distance is much closer to the earth, allowing plants to absorb more short wavelengths, which are mainly in the white and blue colors of the spectrum. Blue wavelengths are needed in the Veg stage of growth, yielding strong stems to support heavy fruit and thick leaves to increase nutrient and sunlight intake.

When fall nears, the Sun is farther away and wavelengths are longer. These are mainly in the red colors of the spectrum. When plants detect longer wavelengths, they release all their fruit/flowers to prepare for hibernation. At this stage, plants need as much red light as possible to produce healthy and lush flowers.

TrueSun Smart Spectrum delivers the optimal levels of blue, red and white light for each stage of your plants' growth.

Distance from the Light to the Plant

One of the biggest mistakes people make when using LED grow lights is not placing the light at the proper distance from the top of their plants (also known as the canopy).

BloomBoss TrueSun LED grow lights perform best when the light is close (but not too close) to the canopy.

We recommend initially positioning your light 24” from the top of your plants during the Veg cycle and gradually lowering the light to a distance of 18” based on how your plants respond.

If you want your plants to continue stretching, keep raising the lights as the plants grow. For taller leaner plants, increase the distance between the light and the top of the canopy. For smaller, bushier plants, decrease the distance. As your plants start to grow, keep the distance between the light and the canopy consistent.

During the Bloom cycle, position your light 18” from the top of your canopy, gradually lowering it down to a distance of 12.” During the later stages of the Bloom cycle, once the plant has produced flowers, experiment with more aggressive positioning.

Remember to always watch how your plants respond because they will tell you whether they want the light closer or further away.

Caution – Positioning your light too close will stunt growth and possibly cause bleaching. Too far will cause stretching. When raising or lowering your light, make sure to move it only a few inches, allowing time to transition before moving again.

Photoperiod - Light Cycle Management

Most plants will keep growing in the Vegetative stage as long as they “believe” it is early spring or summer. Outside, this happens naturally as the seasons change. Inside, growers use timers to manage their lights and “tell” their plants when to start blooming. For the best Vegetative growth, give your plants 6 hours of darkness per 24-hour period.

Once your plants have reached the desired height (remember, most plants double in size when they bloom) and look strong, it is time to change your light cycle to 12 hours ON and 12 hours OFF. This tells your garden that fall has come and it's time to begin the Bloom stage. A lot of growers dedicate a room specifically for plants that are blooming.

During dark cycles, it is very important that no light enters your growing area. Any light can disrupt and will negatively impact flowering, severely reducing your garden’s yield and quality.

During light cycles, both the Bloom and Veg switches should be on for maximum light output. In this mode, a lot more red light is introduced, completing the TrueSun Smart Spectrum.

To control and manage your light's cycle (turn on/off), you will need to use a timer. BloomBoss recommends using Wi-Fi enabled timers by D-Link for easy control of your garden’s schedule as well as energy management and remote monitoring from your smartphone or tablet. Please contact your BloomBoss retailer to purchase this and other Wi-Fi based garden automation, security and monitoring products.

Air Flow

Ventilation is critical to the success of your indoor garden.

Oscillating fans circulate the air within your garden. By simulating a light breeze, fans help to produce stronger, fuller plants. They also help to prevent mold and fungal disease.

An exhaust fan is the key element of any air ventilation system as it renews the air and regulates the climate of your garden. As BloomBoss LED grow lights produce far less heat than traditional HPS/MH lighting, temperature control is less of a concern, but still important.

Growing Medium

Many new indoor growers believe their only choice is soil, but there are other growing mediums such as:

• Hydroponics (Water)

• Inert Materials (Coco, Peat, etc.)

Take the time to do your research and determine which medium makes the most sense for your grow.


Your plants will grow in many temperature ranges. However, for optimal growth, we suggest a consistent room temperature between 75 and 80 Degrees Fahrenheit (F).

In most indoor gardens, your BloomBoss LED grow light should not require any additional cooling. In rare situations, depending on your garden’s configuration and number of units running in a confined space, some venting may be required to keep your temperature within acceptable ranges.


The ideal humidity of your garden should be maintained at 50% during the Veg cycle and less than 30% for the Bloom cycle. Lowering the humidity when in Bloom will help to prevent mold and fungal disease.


Plants have different nutrient requirements throughout their life cycles.Your local indoor garden center or hydroponic store is a great resource to help you through the selection process.


As BloomBoss LED grow lights produce less heat than traditional HPS/MH lights, you will need to adjust your watering and feeding schedule accordingly. For best results, maintain a consistent PH in a range from 6 - 6.5. Hydroponics like a range of 5.5 - 5.8.
