  1. If you’re growing Critical autoflower seeds and you’ve noticed the stems on some of the plants are thin and weak, you’re probably feeling concerned. Fortunately, there are a few things you can do to help strengthen your plants’ stems and give them the best chance of thriving.

    First and foremost, it’s important to understand that genetics play a big role in determining how sturdy a plant’s stem will be. Autoflowering varieties in particular are known for having thinner and weaker stems than many other varieties. This is because the shorter vegetation period of the autoflowering life-cycle gives the plant less time to develop its stem structure. That being said, there are still a few things you can do, both in the short and long-term, to help lend your plant’s extra support.

    Starting in the short term, you can begin by providing extra support to the stems of your plants. This can be done in a few ways. For example, you can loosely tie the stems of the plants to a stake to help them stand upright. You can also ‘train’ the plants by tying their stems in the direction you’d like them to grow. Even in the early life stages of the plants, this can be beneficial. It’s important to do this with lightly pressure, however, as applying too much pressure can actually damage the plant.

    In terms of other environmental factors, look for anything that may be causing extra stress on the plant’s stems, such as high winds or temperatures, or excessive light exposure. Controlling these aspects of the environment can help your Critical autoflowering plants in the long-term.

    One final step is to consider adding additional support measures in the long-term. This could include adding a trellis or other supports to your grow-room, to give your plants something to lean on while they’re growing. This can be very useful, particularly if you’ve got large plants with heavy buds that may be causing the stems to droop or bend.

    All in all, while some of the weakening of the stems may simply be due to the genetics of the particular Autoflowering Critical variety you are growing, there are plenty of measures you can take to offer extra support and help strengthen the stems of your plants. With the right combination of environmental and support strategies, you can help your plants continue to thrive and reach their full potential.
