How to grow grass on a windowsill: all you need to know
Cannabis grows best outdoors in the sun or indoors under strong lights, but it is also possible to grow cannabis plants on a windowsill. Read on to find out how.
Not everyone has a great outdoor spot to grow cannabis, and not everyone is willing to invest in expensive indoor growing equipment. At the same time, most of us have at least one window sill in his apartment. And while it’s far from optimal, it’s still possible to grow a healthy cannabis plant on a windowsill. Here’s how.
STEP 1: HAVE REALISTIC EXPECTATIONS
Cannabis is a hardy plant that can grow in many different conditions and even on a windowsill. However, it is really important to understand that your plant will only produce small amounts of bud under these conditions.
Don’t be misled by the photos you see posted by professional growers and even seed banks—a cannabis plant grown on a windowsill won’t look like those weedy bushes. On the other hand, it will usually produce little more than a few grams of bud, the quality of which will depend on the amount of light, nutrients and care that you can give to your plant.
STEP 2: CHOOSE THE RIGHT PLACE
Cannabis plants need lots of light. If you decide to grow on a windowsill, choose a window that receives as much direct sunlight as possible. Cannabis also likes warm temperatures of 18–30°C and humidity levels of 40–70%. When possible, try to achieve these conditions, either artificially using air conditioning and a humidifier, or naturally by growing at the right time of year.
Remember that, in nature, cannabis grows from spring (when the seeds germinate) until early fall or winter when the plants wilt and die naturally.
STEP 3: CHOOSE THE RIGHT VARIETY
Choosing the right cannabis strain is always important when growing cannabis, but if you’re growing on a windowsill, using the right genetics becomes paramount.
First and foremost, you need to use a cannabis strain to autoflowering when you grow on a windowsill. Unlike photoperiod strains, autoflowering strains do not flower based on a change in the light cycle. Instead, they begin to flower automatically once they reach a certain age. This is really important when growing on a windowsill, as you won’t have enough control over your lighting to force a photoperiod strain to flower.
Then you need to grow super hardy varieties that don’t take up a lot of space. Avoid tall sativas, as they require far too much space to grow well.
STEP 4: START YOUR SPOTS
Once you’ve decided on a strain and have your seeds, you need to germinate them. To do this, place the seeds between a few damp paper towels and keep them between two plates in a dark cupboard. They should start sprouting within a few days, after which you should plant them in the ground.
For young shoots, you can use a clear plastic glass as a pot, which allows you to closely monitor the roots of the plant as they grow. Ensure
you to drill some holes in the bottom of the glass for drainage and fillthe ordinary moist earth. Make a hole about 1 cm deep, place y your seed and coverthe. Next, place your seedling on your windowsill. It should break through to the soil surface within a few days.
STEP 5: TAKE CARE OF YOUR SPOTS
The young plants of cannabis are very fragile. They like warm, humid environments, so it’s a good idea to cover your seedling with a plastic bag and sprinkle some water with a mister indoors every few days to retain moisture. . Be careful not to have your hand too heavy, because excess humidity can give a real breeding ground for bacteria and fungi.
Let your seedling grow until it has developed a few nodes and at least one leaf with a full number of fingers (between 7 and 13 fingers, depending on the variety). Once you see the roots pushing through the bottom or sides of the plastic cup, the seedling is ready to move into a larger pot.
STEP 6: PREPARE YOUR POT AND SOIL
Soil is the best medium for growing on a windowsill. And the better your soil, the healthier your plants and the buds they produce will be.
But before you even think about your soil, you must have a pot to house your cannabis plant. Normally cannabis growers use pots with a size between 10 and 40 litres, but of course these are too big for a window sill. Calculate your space and try to give your plants the biggest pot possible, keeping in mind that the more soil the plant has available, the taller it will grow. Also, remember to use a pot that has plenty of holes for drainage.
Once you’ve chosen your pot, it’s time to prepare your soil. The easiest way to do this is to buy high quality soil from your garden center and mix it with about 30% vermiculite. This will give you soil with good drainage, which is perfect for cannabis. As your plant grows, you can use fertilizers to help it reach its full potential.
If you want to avoid fertilizers, you can take the time to prepare your own soil before planting. You’ll always start with commercial potting soil, but over the months you’ll enrich that potting soil with all kinds of ingredients to create a nutrient-rich medium for your plants to grow in.
Start by mixing 3 parts soil, 1 part vermiculite and 1 part worm castings. Then you have to add green sand, dolomitic lime granules and guano. The amounts used will depend on the size of your pot. The packaging of each product should indicate dosage information, so be sure to calculate correctly based on the amount of soil you are using.
Once everything is well mixed, moisten all the mixture and let it sit for three days before planting your seedling in it.
STEP 7: FEED YOUR PLANT
When feeding cannabis plants, you have two main options: commercial nutrients or homemade nutrients, both of which have their pros and cons.
Commercial nutrients can be calculated exactly, so you know exactly what you are giving your plants. They also exist in the form of different specialized solutions for vegetative growth and flowering. However, many of these nutrients are synthetic and need to be flushed from the soil within a few weeks of harvesting, to be sure they don’t leave a streak of produce. chemicals in your final product. If not used correctly, these nutrients can also cause excess nutrient burn on your plants, which can be very negative if the wrong reaction occurs.
Homemade Nutrients, on the other hand, are natural and can be made by infusing food scraps (such as vegetable peelings, coffee grounds and brewed tea leaves) into a “tea” which can then be used for sprinkling. your plants. These teas don’t need to be flushed out of your soil before harvesting and can provide your plants with a wider spectrum of nutrients than just an NPK solution. The downside is that you don’t know exactly what nutrient concentrations you’re giving your plants. These teas also take time to prepare.
NOTE FOR SIZE/TRAINING
Cannabis growers routinely use pruning and training to force their plants to grow in a specific way and develop more heads. When growing on a window sill, only very light pruning is advised. Remember that you are working with small autoflowering plants that usually don’t have time to fully recover from high stress training before going into flowering.
CHOOSING THE RIGHT VARIETY TO GROW ON YOUR WINDOW SILL
As we mentioned earlier, choosing the right genetics is very important when trying to grow cannabis on a windowsill. Below is a quick list of our favorite autoflowering strains that will hold up well in these conditions.
LITTLE DWARF AUTOFLOWERING
Little Dwarf Autoflowering, as the name suggests, is a very small cannabis strain perfectly suited for growing in tight spaces like a windowsill. As a cross between Skunk and ruderalis, this strain is super-hardy but still capable of producing very aromatic buds. Little Dwarf Autoflowering typically takes 7-9 weeks from seed to harvest and produces 40–80g/plant, depending on its environment and the skill of the grower.
POWER PLANT XL AUTOFLOWERING
This little indica-dominant powerhouse is an alternative to autoflowering to the original Power Plant XL. This strain can produce a real good harvest even in colder conditions and has slightly less dense buds, which means it is less susceptible to bud rot and other fungi. She will be ready in around 8 weeks from seed to harvest, after which she will reward you with delicious buds containing up to 15% THC.
GREEN AK XL AUTOFLOWERING
AK-47 is an epic variety renowned the world over. Our Green AK XL Autoflowering combines these excellent genetics with ruderalis, resulting in a superb auto that can produce up to 100–150g/plant of top-shelf bud. Even better, these plants barely exceed 100cm in height, making them perfect for growing on a windowsill.
