Tips for Cannabis Vegetation Stage 2019

The Vegetative Growth Stage of Cannabis Plants This chapter assumes that you have  germinated  your seeds and now have little marijuana seedlings starting to grow. If you took our advice and have some nutrients in the soil (or water), then this stage can be a fairly easy stage to get through. Temperature & Humidity: Room temperature should stay between 72 - 85 degrees Fahrenheit. Yes, I could say 78 is ideal, but if you can retain your room temperature in this range, you should be fine. Sometimes, being exact will drive you nuts, and sometimes you NEED to be exact. Your humidity is good if 45 - 65 percent can be maintained in your vegetative  grow room . Oh, and yes, your room can get to 60-65 degrees Fahrenheit at night (lights out) without any problems. Lights: Your lights should now be ON for 16 to 20 hours per day (24 hour period) - Light timers or outlet timers control this for you.

What light is best for vegetative growth?

In any garden, the vegetative stage is the foundation for a successful fruiting or flowering stage. After all, it is during the vegetative stage that the majority of the root mass is created and the plant’s structure (the spacing between branches and overall stem strength) is established. It is also during this stage that many growers use manipulation techniques to shape plants to increase yields. But aside from the various plant manipulation techniques used by growers, there is one other vital component that prepares a vegetative plant for a strong finish: the artificial light source. A garden’s artificial light is the sole energy source for all plant growth. It should come as no surprise that indoor growers spend a lot of time and money perfecting their garden’s lighting. The vegetative stage is crucial for the growth of marijuana because it determines how healthy and robust it will be once it enters the flowering stage. This is the point when the structural integrity i...
