420 autoflower seeds can be planted in a large size pot, and will quickly grow into a short sized bush. After 4 weeks, they will flower independently regardless of the amount of daylight. Our top tips to grow this low maintenance strain is to keep the nutrient levels low. We find this lady can take large amounts of water; however, plants prefer a lower E.C level. Also, plant directly into big pots such as 19 liter / 5 gallon pots for the biggest plants possible.

When planting ak-420 automatic seeds outdoors, they can be planted without the need to wait for the later part of the year to induce flowering.

Indoors, ak 420 automatic is a beast of a plant that will deliver monster yields of high-grade buds. We recommend growing these seeds under 18-20 hours of light for the best results. As the AK420 autoflower seeds grow, they will produce a medium-sized, bushy plant that will display a thin fingered, long serrated sativa leaf structure.

<   AK 420 auto Watering Times and Nutrition

Watering your seedlings is one way to provide nutrients. Make sure they are not stressed and deficient, knowing when to water your plants and how much run off there should be, can make a big difference in how healthy the roots become.

When seedlings are growing and during the first 3-4 weeks, this is the time when it is best to feed little and often. Keeping a close eye on moisture levels in the pot is very important, and a good way to make sure the pots are well oxygenated is to gently water around the edges.

After lightly watering for the first 3-4 weeks, we then recommend watering only when the pots are totally dry. The balance of wet and dry will encourage roots to push out, searching for air and moisture. Once the ak-420 automatic plants have been watered, you should wait for the pots to become light and dry before watering again.

As far as nutrition is concerned, there are several ways a grower can provide the relevant nutrients over the life cycle of the plants. The first is using hard foods such as soil and compost combined with a water only diet. The other is to use liquid nutrients that will provide a well-balanced amount of Nitrogen, Phosphorus and Potassium.

autoflowering Cannabis plants will want a high level of Nitrogen available for the first 4 weeks, then a P-K dominant nutrient solution from week 4 onwards. During flowering, it is best to cut off Nitrogen levels and focus on Phosphors and Potassium. Bat guano can be an excellent organic nutrient for autos, otherwise any flowering feed from a Cannabis brand will work wonderfully.

<   Seedstocker’s 7 Top Tips for growing AK420 autoflower strain

1. Make sure that you provide plenty of space for the plants to grow indoor or outdoors. AK420 will express her sativa dominance, meaning plants can grow quickly, and become large sized. Our tip here is to provide at least 150 cm in height and lots of width.

2. Unlike photoperiod Cannabis strains that are kept in a vegetative state for long periods of time and can be repotted, auto’s prefer to start directly into a large pot. When it comes to AK 420 auto, avoid transplanting from a small pot into a large pot once the seedlings are growing.

3. When it comes to making your nutrient solution, it is better to feed nutrients less frequently than with other Cannabis plants. Despite her large sized appearance, she does not like a high number of nutrients. If using chemical nutrients, then our tip here is to use an E.C pen to find out the strength of the nutrient solution.

4. When planting indoors, we recommend to provide the plants with 18-20 hours of HID lighting for the best yields possible. Although, we find with 18 hours of light and 6 hours of dark, 420 genetics auto will produce the best plants.

5. It is a good idea to add support to the long side branches, in order to avoid the buds from toppling over with excess weight. Our tip here is to use bamboo canes or a net trellis to add support, especially during the final 21 days of flower production.

6. Thanks to the abundance of sugar trim, making water hash and dry sift has never been so rewarding. AK 420 auto will produce some incredible full melt hashes. Our tip here is saving all of the leftover leaves and not letting anything with trichomes go to waste.

7. One of the most important things to consider when providing the best start for any auto flowering genetics, is to ensure the growing medium is airy and full of air pockets. Our tip here is to use a growing medium that has a high ratio of perlite, and make sure the growing medium is slightly watered and does not become oversaturated, specially during the first 3-4 weeks
