ThinkGrow
ThinkGrow Model-I plus 720W Linear LED Grow Light $ 1,207.50 $ 1,428.00
The ThinkGrow Model I-Plus LED fixture is a high-performance grow light designed specifically for horticulture cultivation. The compact design, featuring a built-in driver, ensures a balance between energy efficiency and an optimal human work environment. The innovative V-shape design on the LED panel enhances light distribution, allowing for a reduced height from the canopy, which in turn minimizes light energy loss. Benefits of Light Intensity This LED grow light offers outstanding efficiency with a light intensity of 2.7 µmol/J, ensuring that your plants receive the maximum amount of usable light energy per unit of electricity consumed. High light intensity promotes vigorous plant growth, enhances photosynthesis, and increases yields. This efficiency translates into lower energy costs, making it an economical choice for both commercial and home growers. Benefits of the Color Spectrum The fixture features four fully controllable spectrum channels—UV, White, Deep Red, and Far Red—providing the flexibility to dial in the exact light recipe your plants need. UV (Ultraviolet): UV light stimulates the production of essential oils and resins, enhancing the flavor, aroma, and overall quality of your crops. It also helps in controlling mold and mildew, ensuring healthier plants. White Light: Mimicking natural sunlight, white light supports all stages of plant growth, from seedling to flowering. It provides a balanced spectrum that enhances overall plant health and growth. Deep Red: Deep red light is crucial for the flowering and fruiting stages of plant development. It promotes the production of flowers and fruits, leading to higher yields and better-quality produce. Far Red: Far red light influences plant morphology, encouraging stem elongation and leaf expansion. This spectrum is essential for optimizing canopy penetration, ensuring that light reaches the lower parts of the plants, promoting uniform growth. With the TrolMaster HCS-2/3 controller, you can fully control these spectrum channels, tailoring the light to the specific needs of your plants at different growth stages. The external control capability allows for the management of up to 256 fixtures per channel, making it a versatile solution for large-scale operations. In summary, this high-performance LED grow light not only maximizes energy efficiency but also enhances plant growth through its innovative design and spectrum flexibility, ensuring your plants receive the precise light they need for optimal growth and yields.
