24 hour lights for growing weed

Speaking of lightning, there’s a big difference in types of lightning used in different stages of plant development. Having a fancy HID, CFL, or LED grow light can bring you tremendous growth and prosperity, but a poor choice can also bring your plant down and wither it to a low-quality bush.

After researching the topic for a while, I realized that people form their opinions based on their personal experiences, and base their assumptions on their previous experiences with growing.

The plant itself is the first variable in the equation; many species react to light differently and require a different amount of it throughout the day/week/lifetime.

The flowering stage starts after the plant starts receiving 12 or more hours of darkness. During this process, the growth is not as quick as in the veg stage, and the plant starts developing buds. A properly educated and careful-enough grower can put this fact into good use, and maximize growth and produce, which is often the case in growing cannabis for commercial purposes.

By definition, the plant of cannabis classifies into photoperiod plants, which means it reacts to both light and darkness. There are also auto-flowering cannabis plants, which will be explained later.

As a conscious grower, you should ought to provide the best conditions for your plants to grow and bring the best yields. Lightning is one of the most important aspects of successful growth & plant development, so having it set in order is a must.

But, the situation isn’t that simple to come to a conclusion that easily. There are more factors included in the process of growing & proper lightning.

Digging deeper

Acknowledging the above-mentioned, we have to address the plant next. Throughout the growth & development, the plant of cannabis goes through several phases, each having its distinctive requirements and best practices.

Cannabis will stay in the vegetative stage as long as the plant gets short nights (less than 11-12 hours of darkness each day)

Most indoor growers provide 18-24 hours of light a day (known as 18-6 or 24-0 light schedules). Giving your cannabis plants more hours of light each day in the flowering stage will encourage faster growth.
