how big can autoflowers get

Simply spoken, reverse osmosis is a filtration process that results in pure, ultra-filtered water. With this, you are in total control of the mineral profile of your water. This can benefit the growth of your plants and your yield.

A healthy and strong root system means healthy plants with great yields. Consider “smart pots”, like the RQS fabric pot, to give you an advantage in this domain. With their ability to prevent plants from becoming root bound, fabric pots are better for overall development.

If you’re an expert grower and not afraid to put a knife to your plants, you can see whether topping will work for you. Just ensure that everything else is under control before looking into these more-involved plant training techniques.

9. USE REVERSE OSMOSIS WATER

Whether you are planning an indoor or an outdoor grow, make sure to start your seedlings indoors.

If the substrate is too compact, you can make it suitable for autoflowers by adding some perlite and coco coir. See our article here for more tips on the best soil for your autoflowers.

The sea of green, or SOG, method involves growing many small plants in close proximity to max out space and yields. This is especially effective in otherwise small grow-ops, and there is no better candidate than autoflowering strains. Their fast growth and short stature essentially do everything for you. Plus, no pruning or excessive handling is needed.

Soil growers are advised to use lightly fertilised soil for autoflowering cannabis. Heavily fertilised soils will burn these babies. Aside from supplements like enzymes, vitamin B, and beneficial fungi, autoflowers don’t really require large doses of base nutrients during their short vegetative stage. Heck, with good-quality soil, your plants may do just fine without additional nutes all the way to harvest.

Pot size is another very important factor. The amount the roots grow underneath will reflect directly in the size of your plant, so if you grow in a 5 L pot your plant will be smaller than if you grow in a 10 L pot. Even if there’s a difference in the size of Sativa and Indica-dominant strains, pot size will decrease their overall size, as they won’t have space for the roots to grow.

Follow the same logic to obtain the number of plants for square feet.

Genetics

Now, with light bulbs this is different and there indeed is a way to calculate the wattage you will need for your plants, this way you are not calculating how many square meter per autoflower you need but how much light you need. Let’s continue with the example we were following before. We have a space area of 6 square meter (64.5 ft 2 ) and we already know we can fit 30 plants in it, what’s the wattage we will need.

Meaning, we can fit 36 plants in a Sea of Green of 6 square meter, and to calculate the wattage, we have to multiply the number of plants by 75 W, so 36 x 75 w = 2700 W.

There are several things that help control the size of an autoflower, things like genetics, lights, and pot size make it possible to grow up to 6 plants per 1 square meter. Almost all cannabis consumers that want to start cultivating their own cannabis want to fulfill their needs without having to spend too much. To do that, you have to make the most out of your grow space.

Due to a shortage of time, not every training technique working for other cannabis plants suit autoflowers. For instance, HST or High-Stress-Techniques work very well on photoperiod plants, but autoflowers prefer Low-Stress-Techniques or LST.

Autoflowers growing outdoors usually receive only 12 hours of proper sunlight, and you’re probably wondering if that’s enough. However sunlight is the most powerful light compared to artificial systems set up by humans, so autos take advantage of the situation and produce maximum yields outdoors.

4) Reduce nutrient strength

It’s common for beginners to load their plants with too many nutrients and burn them. We get that you love your plants, but you’re only harming your autoflowers by feeding extra nutes. Photoperiod plants have bigger roots, but autoflowers are comparatively smaller and the nutrients have to be adjusted accordingly.

In particular, full-spectrum LEDs work the best for any type of autoflower. The higher the lumens, the better the yields, but if you cannot afford expensive lighting equipment, CFLs will work well during the vegetative phase.

As a grower, your job is to ensure that all the buds receive equal light, and that’s where LST helps a great deal. Most growers begin LST after the plants are “Topped”. Topping is another technique that involves cutting off the tip of the main stem, forcing the plant to grow more colas rather than one. Beginners can even “FIM” their plants, which is another method where you cut off only a part of the tip instead of cutting it entirely.

It’s also important to do some research to purchase autoflowering seeds of the highest quality. You can do everything right but it may all be for naught if the strains aren’t meant to produce high yields. For example, Fastbuds catalog shows you seeds ranging from XXL to L yield category, and you can choose anything depending on the space available.
