You can recognize pictures of plants under LED lights through their purple hue. For many years these purple boards of diodes were the only option if you wanted to grow with LEDs.
Metal Halide lights are usually used during the vegetative phase of growth, but can also be used during flowering. Their bluish light is perfect for vegging plants, and while this will get the job done, many dedicated growers switch to another lighting solution once buds start to form.
Like CFLs, HIDs also come in a few varieties.
LED Grow Lights
Autoflowering seeds grow, well, automatically when cultivated outdoors. Plant, water, and fertilize them, then let the sun and mother nature do the rest. Indoor growing is more technical, but just a bit. Whereas the Earth and the sun provide abundant soil and light, you’ll have to provide those for your plant. You’ll also need to pay a bit more attention to plant nutrition, as well as install a carbon filter to keep the smell away unless you’re like us and want your home to smell like fresh marijuana all the time. Here’s all you need to know to get started growing autoflower weed indoors.
There are a variety of soilless options to choose from, but the most popular for growing Cannabis is Coco Choir. Made from coconuts, Coco looks like soil at a glance but is ideally suited for growing friendly bacteria that will give your plants nutrients. You don’t have to use it by itself; you can also mix it with traditional soil to create an ideal blend.
These long tubular lights often plug into panels of four or five lights and take up significantly more space than CFLs, but they produce a light spectrum slightly better suited for cannabis growth. You can find them at any garden center or home improvement store. When growing seedlings or clones, be sure to keep the light far away. While you can keep T5 lights closer to mature specimens, their light is too intense to stay close to more fragile, younger plants.
In general autoflower strains are almost always hungry for calcium and magnesium, so you should get a brand that provides those vital nutrients. Beyond that, don’t stress over it. The growing environment and medium, more than strain, determine what kind of nutrients you need to provide your plants. Since those are unique to each grower, it’s hard to give generalized advice.
Cannabis can only uptake nutrients when the soil surrounding the root zone has the right pH value. The optimal pH range here is 6.0–7.0. For growing in other media, such as coco, the pH should be lower, ranging from 5.5–6.5. If the pH of your water is not optimal (which is likely the case if you use tap water) and plants can’t uptake nutrients, this leads to sick specimens. The right pH is particularly important when growing autoflowers as they don’t have time to recover. You want to ensure your plants get all the nutrients they need during their short period of growth.
Essentially, this entails having multiple plants in different stages of growth at any given time. In this way, you can time things just right so that there is always weed ready to bloom and harvest. This gives you the potential for a never-ending supply that doesn’t require excess effort from you!
The best solution is to make your own soil mix at home.
TIP 9: CUT THE NUTRIENTS
To carry out a SOG with autoflowers, you’d simply plant your seeds directly into even smaller containers that allow you to fit as many plants as possible into every square metre of space. How many plants you want to use for your SOG, as well as their exact pot size, will depend on the space you have available. This may also vary from strain to strain. Feel free to experiment to find the ideal pot size and number of plants that produces the best yields in your indoor grow space.
That said, you shouldn’t need very large pots for your autos as they won’t usually get very tall.
You should nevertheless choose a pot large enough so the plant doesn’t get root-bound, but instead has plenty of space to grow.
More than anything else, genetics will play the biggest role in determining the final outcome of your grow operation. But what makes the right strain? Well, let’s start with your personal preferences, for example, what type of effect you want from your cannabis. If you’re smoking to get blazed with the best and the latest, you can’t go wrong with THC monsters like the super dank and potent Royal Cookies Automatic or Royal Gorilla Automatic, our automatic variants of two popular strains!
How do you water cannabis properly? For starters, don’t water your plants on a fixed schedule, but instead only when they need it. You should always allow the soil to dry out between waterings. A good way to check if your plants need water is to lift up the pots. You should have a pretty good idea of how light a dry pot is compared to one saturated with water. As such, only water when the pot is light and the soil has dried out. Overwatering can be deadly, so it’s better to err on the side of caution.
For example, cannabis needs more nitrogen in the vegetative stage. In the pre-flowering stage, nutrients with more phosphorous are preferred, and in the flowering stage needs a lot more potassium than nitrogen or phosphorous.
The yields depend on genetics, environment, stress, growers skills, and etc.. But in general, you can expect between 50-110 grams per plant.
6. Do not transplant
Most autoflowers reach a height of around 50-100cm but a plant’s size depends on the genetics and growing conditions. Also, all strains are different so you will find Sativa and Indica-leaning autos; Most Indica hybrid autoflowers will stay around the 80-120cm mark but Sativa-dominant autoflowers can reach up to 175cm tall.
Of course you can, you can grow autoflowers in a greenhouse all year round as long as you keep the inside temperature to a minimum of 15°C and there’s enough ventilation, airflow, and sunlight.
If you don’t want to bother about fertilizing at all, you can even try growing autoflowers organically. There are various ways to make your own organic soil, but you can buy some in your local store to start with. Organic soil is premised with nutrients, so it’s ideal for someone that doesn’t have a lot of time. For growers that don’t mind putting in the efforts, composting and building super soil is the best soil mix for autoflowers.
