When plants reach their mature size and begin flowering, they need more phosphorus, the nutrient most essential for budding. Check the N-P-K ratio listed on every package of nutrients to be sure that you’re using a high-nitrogen formula during the vegetative stage and a high-phosphorus fertilizer when your plants are flowering.
You want to keep the lights 18 to 36 inches above the tops of the plants. Check to be sure they’re not too hot by putting your hand under the lights at the same height as the tops of the plants—if it’s too uncomfortable for you, it will be for your plants as well.
3. Train Your Plants
Consistent ventilation with outside air is all the CO2 plants need during budding. More CO2—as much as 1,500 ppm—will amp up your plants’ growth rate and yields. Pushing the level to as much as 1,500 ppm of CO2 makes the maximum amount available to your crop during the crucial period when the buds are forming and fattening up. You can get a simple CO2 generator for less than $120.
2. Change Nutrients for Each Stage
You want the biggest and the best harvest? Then it’s all about the details! With these seven key strategies, your crop will be bigger and better than ever. Achieving these results is easier than ever. Read on to learn mroe about how you can increase the size and quantity of your harvest.
For reference, you can expect to grow up to two ounces if you use a 200-watt CFL lamp in a standard grow cabinet measuring 3.5 x 1.5 x 6.5 feet. However, experienced growers may receive double the yield. If you use a 250-Watt HPS lamp in a room of the same size, you could get up to five ounces or double that amount if you have prior experience.
You can invest in a CO2 generator if you are growing lots of cannabis plants. Be careful, though, as excessive CO2 levels are harmful to humans.
In practice, novice growers encounter plenty of difficulties and often end up with substandard results. To get the most out of your harvest, you must identify the strains you want and understand the importance of growing enormous buds. If you didn’t know, a plant’s bud appears after the plant enters the flowering stage. While the female cannabis plant leaves contain small amounts of THC, the buds are significantly more potent.
4 – Lighting
You won’t get healthy buds unless your plants are exposed to their preferred temperature and humidity levels. These levels vary during the different stages of a marijuana plant’s growth cycle:
Your marijuana plants require CO2 for photosynthesis. More is better as far as carbon dioxide is concerned because an increased amount boosts growth. It is also essential to add extra CO2 when increasing the intensity of the lighting. For reference, the air we breathe contains 350-400 parts per million (ppm) of carbon dioxide. Your plants use the CO2 and combine it with light to create the sugars that are pivotal to their growth.

5 – Carbon Dioxide
If the pH of the soil is below 5.8, your plant won’t absorb magnesium. This becomes apparent when your cannabis’ leaves begin to turn yellow. If you are using a non-soil growing medium such as Rockwool, keep its pH at around 5.5. There are various products available online to either increase or reduce soil pH levels.
When applying nutrients, always begin slowly and give half the dose to see how your plants react. Over the next few weeks, increase the nutrient level if you don’t believe the plants are growing quickly enough. It is best to add nutrients every 1-2 weeks.
