The optimal temperature during the day is 75°F to 86°F (24°C to 30°C). Higher or lower temperatures will reduce flowering rates and will have a negative effect on yield and quality.
The vegetative phase lasts about 45 days, during which time the plant requires a significant amount of light strength. Nutrient requirements are high, especially nitrogen, potassium and micronutrients.
SOIL and pH LEVEL
When using artificial light, the light intensity will have an effect on the total growth, growth duration, water management, and nutritional demand of the cannabis plants.
GROWTH (VEGETATIVE) PHASE
Cannabis can be grown in soil or soilless media. The optimal pH for healthy growth ranges between 5.9 and 6.5. The pH level should be controlled during cultivation.
The final cannabis product is usually female-only without female pollination. To prevent male differentiation or crop variation, cannabis is usually planted as rooted cuttings. After a short time for establishment (about 14 days from planting), the vegetative phase will start.
Learn about the main challenge in Cannabis nutrient management throughout the different growth cycles.
In the vegetation stage, you will want about 18 hours of light for your plants. Use full spectrum lights. More Light = Faster Growth.
In the vegetative stage, you’re setting the foundation for how your cannabis plants will develop. Your plants will in search of light – they will stretch as much as possible and get very tall while they try to reach the for more light. If left to grow naturally, there will be many blank spaces between the nodes and branches which will negatively affect your yield.
These steps create a lot less stress for your marijuana plants because they are only tied down or bended. There is no cutting involved. Through bending, you can make your plant grow a horizontal rows of buds. Bend over branches that are taller than the rest. You can try tying them down or use weights. Super cropping is essentially a technique where you bend your plant until the bent point is slightly damaged.
If you want to maximize your yield with dense, bushy plants, you need to get familiar with the various approaches and tricks that master growers employ:
One of our favorite options for the best pots for growing weed are the 5 Gallon Fabric Aeration Pots from iPower, which you can usually find on Amazon in a 5-pack or 10-pack for under $20.
Fimming is similar to topping. It’s called FIM for “F*ck I Missed” because you pinch off
First things first: if your plant is in good condition, the factor that will limit or support your plant’s growth the most will be light. Don’t let them search for light while sitting in a dark spot. Also, don’t let your plants get burnt by the lamps if they’re too tall.
Different cannabis strains lead to very different shapes and sizes of plants. The balance between filling your space as much as possible and giving your plants as much room as possible might take some experimentation and learnings on your side. While a Sativa might grow another 150% after transitioning to the flowering stage, Indica will only grow about 25% more.
Give your plants some time for a strong vegetative phase. Grow it up to 18’’ inches tall, with at least 3 to 6 leaf branches, before switching to flowering phase.
