IV. Vegetative Stage

During the vegetative stage, your autoflower plants will focus on growing strong stems, branches, and leaves in preparation for flowering. Here are some key considerations for caring for your plants during this important stage:

  1. Providing the proper light spectrum and intensity: During the vegetative stage, your plants will need a lot of light to grow strong and healthy. Make sure to provide a light source that emits both blue and red light, as these wavelengths are essential for plant growth. Consider using a high-intensity LED grow light or a metal halide (MH) bulb.
  2. Managing nutrient solutions and pH levels: Your plants will also need a steady supply of nutrients during the vegetative stage. Make sure to monitor your hydroponic nutrient solution and adjust it as needed to maintain the proper balance of nitrogen, phosphorus, and potassium. You’ll also need to monitor and adjust the pH level of your nutrient solution to ensure that your plants can absorb the nutrients they need.
  3. Training and pruning your plants: To promote healthy growth and maximize yields, you may need to train and prune your plants during the vegetative stage. This can involve techniques like topping, which involves removing the top of the main stem to encourage branching or using a technique like the Screen of Green (SCROG) to train your plants to grow horizontally.

Here are some tips for caring for your plants during the vegetative stage:

  1. Provide at least 18 hours of light per day: Your plants will need a lot of light during the vegetative stage, so make sure to provide at least 18 hours of light per day. Consider using a timer to automate your light cycle.
  2. Monitor and adjust your nutrient solution: Check your nutrient solution regularly and adjust it as needed to maintain the proper balance of nutrients.
  3. Monitor and adjust pH levels: Use a pH meter to monitor the pH level of your nutrient solution, and adjust it as needed to maintain a pH between 5.5 and 6.5.
  4. Train and prune your plants as needed: Use techniques like topping, FIMming, or SCROG to promote healthy growth and maximize yields.

By providing your plants with the proper light, nutrients, and training during the vegetative stage, you can set them up for success in the flowering stage. In the next section, we’ll discuss the flowering stage and how to care for your plants as they develop buds.

V. Flowering Stage

During the flowering stage, your autoflower plants will begin to develop buds and produce resin. Here are some key considerations for caring for your plants during this important stage:

  1. Providing the proper light: Autoflower plants don’t require a change in the light schedule during the flowering stage. They will naturally transition to the flowering stage on their own, regardless of the light cycle. However, they will still require a lot of light during this stage to produce healthy, resinous buds. Continue providing them with a minimum of 18 hours of light per day, preferably using high-quality LED grow lights. Some growers prefer a light schedule of 20 hours on and 4 hours off during the entire life cycle of the plant.
  2. Adjusting nutrient solutions: During the flowering stage, your plants will have different nutrient requirements than they did during the vegetative stage. You’ll need to adjust your hydroponic nutrient solution to provide the appropriate balance of nutrients for your plants’ needs. Autoflowers generally require a nutrient solution high in phosphorus and potassium to promote healthy bud development.
  3. Harvesting and drying your plants: Once your plants have reached maturity and the buds have ripened, it’s time to harvest them. Cut the plant at the base and hang it upside down in a cool, dark, and dry place to dry for a few days. Once the buds are dry, they can be trimmed and cured for a few weeks in a sealed jar to improve their potency and flavor.

By providing your autoflower plants with the proper light schedule, nutrient solutions, and harvesting and drying techniques during the flowering stage, you can ensure a bountiful harvest of potent, high-quality buds.
