Quick Summary: Ideal Flowering Stage Environment
- Temperature – 65-80°F (18-27°C)
- Humidity – 40-50% RH
- Grow Light – Bright light with far-red in the spectrum (high-UV is a bonus)
- Airflow – Fresh air and a gentle breeze
Now that you understand what you’re aiming for in a general way, let’s dive deeper into how environmental factors affect bud quality so you know exactly what to focus on.
How TOO-FAR LIGHT Affects Bud Quality
- Buds don’t get as big as they could have
- When lights are way too far, they basically stop growing altogether
- Otherwise, plants tend to be happy at relatively low light levels…
Keep lights the proper distance away to maximize bud quality and yields
Every grow light has an optimal distance from plants. This LED grow light does best at 18-24″ away depending on the strain and bulb used.
How LIGHT SPECTRUM Affects Bud Quality
- UV (Ultraviolet): increase trichomes and smells
- Blue: a spectrum that’s heavy in blue tends to keep buds smaller, may contribute to more trichomes, and may shorten the flowering stage
- Green: necessary for plant health and fastest growth
- Red: grow lights with a lot of red tend to produce bigger buds and may cause the flowering stage to last a bit longer
- Far-Red: necessary for photoperiod buds to develop properly, seems to contribute to the best bud development
The best flowering grow lights have a bit of blue and green, lots of red and far-red, and bonus if it produces UV light. The best flowering grow lights often appear white, yellow, or pink to the human eye.
