The Optimal Veg Light Intensity

This is an Ongoing Blog post from Instagram.  We will update more shortly. 

What’s the proper Veg PPFD. Well, depends on your goals – according to this study 600 – 900 ppfd or even higher (1000+ ppfd) if you want compact plants (Vertical Growers).⁣⁣For experienced growers

If you are attempting to keep your plants compact, before the flower stretch, a blue enhanced spectrum, such as the 𝐌𝐚𝐦𝐦𝐨𝐭𝐡 𝐕𝐞𝐠 𝐒𝐞𝐫𝐢𝐞𝐬, + 𝐇𝐞𝐚𝐯𝐲 𝐋𝐢𝐠𝐡𝐭 will maximize the plants morphology to be compact with the most bud sites. ⁣⁣

We work with the world’s largest Vertical Growers and this is the type of research and analysis that is presented. Yours for free as a loyal Mammoth follower. 😃 Enjoy. ⁣⁣

Light intensity is one of the most important environmental factors for plant growth. We have shown multiple studies of Cannabis yield being Linear to Yield (Zhen 2021; Eaves 2019; Bugbee). For the most part, light intensity effects yield and spectrum effect plant morphology and cannabinoid production. However, we can steer the plants morphology with light intensity. ⁣⁣

If you are a Vertical Grower or have limited space – you should be pushing your plants with heavy light in Veg and with a Blue enhanced spectrum to maximize your space. Visit the website for this full study. ⁣⁣

In contrast with high-intensity light, low-intensity light is frequently reported as a factor for photoinhibition (Long et al., 1994). In addition, the effect of low light levels on plant growth and photomorphogenesis is well known; for example, they can lead to plant stretch or increase height. ⁣

It’s preferable to utilize a light that has both cool (5000k) and warm light (3000k). A larger proportion of blue light has an inhibitory effect on cell elongation, which leads to shorter stems and thicker leaves. Conversely, a decrease in the amount of blue light will cause a larger leaf surface area and longer stems. Too little blue light will negatively affect the development of plants.⁣

In Cannabis, plants grown under more blue LED were shorter and more compact compared to those grown under the red HPS treatment (Magagnini 2019).
