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).
