The movement of air is necessary to a grow, because CO2-rich air is quickly depleted and that is a requirement for your plant's photosynthetic process, which causes new plant cells to grow. The heated air due to the lighting needs to get out of the grow too, as it dries out the plants. Usually, table fans are used in indoor grows, combined with ventilation systems, but that is probably not practical for your micro grow. You put one at a low point that will act as your intake fan and put another one in a higher position to act as an exhaust fan.
This way, as heat rises, the hot air will come out first, replacing it with cooler and fresher air. Don't forget to use some kind of filters on the fans which will help you battle unwanted pests and odors. Watering your micro grow becomes tricky after a while, as the plants become bushier and expand in width. You will need to use a small water system or make the grow accessible from the side to water your plants from the bottom. Don't forget that plants in micro grow need more water than plants in regular grows, as they have less root space. It was mentioned before, that space is the main difference between micro growing and a regular indoor grow. This lack of space usually calls for shorter and bushier plants, which is shown in the choosing of the right strain. There are other ways to influence a plants growth, such as various growing techniques: topping, super cropping,screen of green (ScrOG) and low stress training (LST). Topping is the process of cutting off the very top of the plant, which stimulates the plant to grow new secondary branches.
This way, the plant grows in width and not height, growing in a bush-like shape and creating more buds. Super cropping (or HST – high stress training) on the other hand, requires you to break the stem of the main branch. You need to break the stem in such a way, that the plant thinks it is gone for good and starts growing side branches, but not completely, so that the main branch can recover and grow to a smaller height. The ScrOG technique requires you to put a mesh wire screen between the soil and the light source. Once the branches grow through the screen, you can tie them to the screen to force them to grow horizontally, hence the name. With ScrOG you manage the height of the plant and all the tops get the same light. LST is a somewhat similar technique, where you tie your plants higher branches to the soil, forcing the plant to grow side branches and more colas, with the end result being a higher yield in a smaller space, perfect for micro growing. Beginner growers need to know that a micro grow isn't a worthy substitute for a real indoor or outdoor grow. But, it is perfect as a starting point to develop that green thumb and to learn about the important things you need for a good cannabis grow. Feel free to try out and experiment with new strains, techniques and instruments, as long as you treat your plants with care. The whole process of growing a plant is a reward in itself, not to mention the harvest, so what are you waiting for? Royal Dwarf truly is a miniature cannabis specimen that can remain at tiny sizes of 40cm tall when trained in the ways mentioned above. This plant was bred for one reason and one reason only: stealth. Growers can easily cultivate multiple Royal Dwarf plants in their home without a single suspicion being raised. She can easily be grown within modified kitchen cupboards, wardrobes, boxes, and computer towers. Small LED lights can also be used within these tiny spaces to avoid giving off too much heat. Royal Dwarf is essentially the autoflowering version of the legendary Skunk, and was made using a Skunk strain along with a specific ruderalis cultivar. She offers stimulating but subtle sativa highs fuelled by THC quantities of 13%. She can therefore be smoked all day long whilst allowing the user to stay on top of their game and not get too high. Her small yet compact flowers offer sweet and citrus tastes. Royal Dwarf will be ready to harvest a mere 8–9 weeks after seeds have been germinated. Plants grown indoors will provide yields of up to 200g/m² and won’t exceed 70cm in height. Plants grown outdoors within garden beds or guerrilla grow spots will produce harvests of 30–80g/plant and reach heights of between 50–90cm. Key Takeaway: You Can Use LST (Low Stress Training) to Force Any Marijuana Plant to Grow Into Any Shape You Want.
LST allows you to train your marijuana plants to grow into basically any shape. This gives you the power to force any strain to grow short, giving you the ability to grow a short Sativa or Haze, strains which normally grow too tall and stretchy to get good yields indoors.
To do this, you physically force the plant by providing no other options. You actually bend and gently manipulate your plants to grow into your desired shape, like an artist or scuptor. I highly recommend getting a spool of twisty tie or garden wire (soft, bendable wire, specifically made for the garden) to tie your plants down with.
