How and When to Transplant Cannabis Seedlings
The seedling stage is perhaps the most important phase of the entire cannabis life cycle. Whether you grow from seed or clone, the practical part always begins with the growth of a seedling. Repotting is important. Get wrong and you could lose the harvest. Proceed correctly following our guide, and you will get an excellent ganja. THE IMPORTANCE OF TREATING WITH CANNABIS PLANTS After germination or cloning, seeds and cuttings need a welcoming place to develop their roots. The main goal of cannabis during its seedling stage is to develop a healthy and strong root zone. If the growth of your seedlings were compromised right away, most likely they will never fully recover and, almost certainly, they will never reach their full potential. In the worst case, the seedlings die and your crop ends even before it starts.
THE OPTIMAL CONDITIONS FOR YOUNG PLANS
Cannabis seedlings must be treated very gently. Think of marijuana as a helpless little girl. If the plants need support, place them on a toothpick or a cocktail stick with a soft string.
The lighting program 18-6 is considered optimal by most growers. The white light generated by the CFL, MH or LED bulbs would be preferable. Even a sunny window sill can work just as well.
The roots grow in the dark. This is why we argue that a light cycle 18-6 or 20-4 is clearly better than a 24-hour cycle of constantly lit light. The humidity should be quite high. To create the perfect habitat for the growth of your seedlings try to keep the RU around 70% and the temperatures between 20 and 24 °C. To keep these parameters constant, get yourself a mini-greenhouse, a thermo-hygrometer and a water spray. The growth of too slender and slender seedlings may be due to genetics. However, in most cases, it is due to an excessive distance between the lamp and the plants. A cold white light of a 250W CFL can be perfectly positioned at 15 cm above a dozen or more plants, without running the risk of burning the leaves.
The Ideal Measures for Marijuana
Providing ideal sized pots for cannabis seedlings is a key aspect to ensure their perfect growth and to optimize the final harvest. In fact, it is well known that cannabis seedlings form very dense and long roots and small pots would severely limit their growth. Therefore, due to the limitation for the roots, which would subject a pot that is too small, it will also end up giving it many nutritional deficiencies; as well as giving it unnecessary stress which will end up considerably reducing the yield of the plant.
The perfect size of a pot depends first and foremost on the cannabis strain you choose to grow:
- For photoperiod genetics a very large pot is recommended, in general, in good environmental conditions they grow much more than autoflowering varieties. Therefore, for indoor photoperiod cannabis plants we recommend starting with a small 10 cm pot, then moving on to an 11 liter pot and finally to a 20 liter pot; the practice will be a little different for outdoors, where photoperiodics will grow dramatically, and much more; pots greater than 20 liters will certainly be needed.
- For autoflowering cannabis strains, which generally keep much smaller than photoperiodic varieties, 11 to 16 liter pots are recommended. A fundamental aspect of autoflowering cannabis is that it would be quite risky to decide to repot them, since in general after repotting a photoperiod plant, the vegetative phase is extended by a week to make it recover from stress. While for autos, not having the privilege of deciding when to flower, they will remain smaller.
Types of Best Vases
Standard pots, readily available at any florist in any city, are good choices for your cannabis seedlings. They can be found in plastic or terracotta. Those in terracotta have the special characteristic of retaining humidity, to be purchased if you want to grow in hot months to keep the plant cool easily; on the contrary they are not recommended in the cold months, in fact in that case an excess of humidity in the soil could very easily lead to the appearance of fungi and parasites.
The key feature of fabric pots is to prevent the roots of cannabis seedlings from intertwining. In addition, another considerable advantage of these fabric pots is the recirculation of air between the roots, this allows the plants to grow even more vigorous by having air recirculation in their main part. These pots have a further great advantage over the others, in fact, it would be impossible to exceed with watering and cause stress, or even death to the cannabis plants, in fact the excess water would not remain in the pot, thus causing root rot, but being fabric vases, the excess water comes out immediately out of the jar.
