It also means you can ensure your plant produces the best crop possible once you initiate flowering. All you need to do to make the switch is adjust the light cycle to 12/12. This becomes even more useful when you're able to make unlimited clones of your optimised plant.
The main drawback is that it'll take around four months to get a substantial yield. However, you'll have a larger and usually more potent plant once you're there. The way these differ from photoperiod plants is written in the name. Regardless of whether you feel the plant is ready, it'll start flowering at a certain time depending on the strain's genetic programming. In one sense, these plants are easier for novice growers because there's less to think about in regards to light coverage and cycle adjustment. On the other hand, due to the limited vegetation time, you have fewer opportunities for mistakes. This isn't ideal for first-timers, but the fact that it only takes two months from germination to harvest is definitely appealing. Autos tend to produce lower, milder yields than their photoperiod counterparts, but modern advances are bridging the gap. Now that you’re familiar with the distinctions between photoperiod and autoflowering strains, we can begin to break down each stage involved in cannabis cultivation.
Even when your plant is a mere seed, the work you put in will dictate its success or failure. Germination is the stage when the first root cracks out of the seed's shell, which takes between 1–7 days . The wet paper towel method is a classic approach here, but you start out with the major setback of tiny fibres all over your new root. You can plant directly in the soil, of course, but you need to ensure temperature and moisture are dialled in. If you want to keep all your seeds safe and clean, we recommend the Royal Queen Seeds Starter Kit. With that, they can enjoy clean, undisturbed germination. Once they get to 2–3cm high, you can remove them from the starter and place them in a suitable growing container. Breaking through the germination stage, plants enter the seedling stage next. At this point, they'll need about 18 or more hours of daily light. After two or so weeks of proper care, though, they'll be well on their way to robust growth. This is the point where it starts to look more like a cannabis plant. There will be one ridged blade per leaf at first, but the blades will get closer to their typical 5–7-finger stage by the end of this period. Until they get the full 5–7 blades, though, the plants are considered seedlings. Along with the increasing blade count, a vibrant green colour is another mark of a healthy plant. To keep them healthy, the two main things to keep an eye on are water and cleanliness. Seedlings are still fragile, so only light watering is necessary. Cleanliness is equally vital due to their disease and mould vulnerability. The perfect home for cannabis seedlings is a propagator, ideally with 70% RH and temps 20-25°C , under either white CFL lights or LED’s. Vegetative growth is normally associated with a transplant at some point as plants outgrow the starter medium be it a Rockwool block or paper cup filled with soil or coco. Continued development of the root zone and robust branching are the top priorities for the grower. High RH of 50% is ideal and cooler temps 20-24°C can promote more females if growing regular seeds. Autoflower cultivators have even less time to play with than photoperiod growers as most autos will race into flowering after just 2-3 weeks of vegetative growth. It’s for this reason that many auto growers plant their autoflowering seeds directly into the final container. The clock is ticking with autos from the moment of germination. Photoperiod strains can be kept in vegetative growth indefinitely so long as 18+ hours of light and suitable conditions prevail. This is what allows indoor growers to keep mother plants for years and why outdoor grower’s plant in springtime.
Indoors or outdoors 18+ hours of light facilitates taking cuttings too. This is the stage to pot up photoperiod plants into final containers, at least a couple weeks before switching to bloom or prior to Summer outdoors.
While the photoperiod strains can be kept in veg weeks or even months to allow for all kinds of pruning and training to boost yield like topping, FIM, LST or even a ScrOG the Auto grower is somewhat limited by time. At this stage, the focus of the grower and plants switches to the production of buds and the grower is already dreaming of a frosty marijuana harvest in the near future. RH needs to be reduced to 40-50% and temps kept between 20-28°C. Cannabis plants will first give you an indication of their sex in the early phase of bloom.
