In this post we’re gonna show you how you can grow DutchFem Automatic cannabis if you don’t want to use expensive lights, but just want to put it in the sun, on your windowsill. Because there’s usually no place for 10 litre pots on a windowsill, we’ll use a pot of 2 litres for this pot. By using such a small size, the autoflower will also be relaively small. The more room the plant gets to root, the bigger the plant will eventually get. The biggest problem with small pots on a windowsill is that they’re usually around heat (above the heater, behind glas, in the sun) and will thus dehydrate quicker once a plant starts to grow. To solve this problem, we use a pot with a water reserve that by use of a fuse will always keep the soil humid. This way, the plants always has access to water (without having to water it 3x a day) and she’ll be able to grow and bloom better!
After having prepared everything, I put the seeds on the soil and sprinkle a tiny layer of soil over it, so that the seeds aren’t visible anymore. Now just a tiny bit of water on top to make the soil humid and put the lid on, and that’s that! In the first pot I put DutchFem Autoflower, and in the second I put DutchFem Dwarf. After 2 days, the first plant (Autoflower) starts showing and one day later, the Dwarf is also starting to become visible. Now the plants have to get as much sunlight as possible.
The first 2 days you can keep the lid on the pots, but because they grow really quickly in this phase, you should remove the lids after 2 days. This is the most important phase for the plants. If they’re in the sun all the time they will grow in height as well as in width, making the stem strong enough to carry the top. But in the dark and/or on cloudy days, the plants can grow in height too quickly, which can cause the plant to be unable to carry the first leaves it sprouts and can fall/break. Should this happen to your plants, then you can solve it in 2 ways. The best way is to put them close under a TL tube or a CFL on days with small amounts of sun (No LED or other bulb) Because of the white light and the low temperature of a TL or CFL, your plants can be very close to it without burning. By leaving a max of 5 cm between the lamp and the the top of the plants, your plants will grow faster in width than in height. Plants are attracted by light, after all. And the larger the distacne, the more they’ll grow in height. For strong and somewhat older plants this is absolutely no problem, but young cannabis seedlings can grow ‘too quickly’ and fall. By putting them closer to the light source, the plant ‘feels’ that they shouldn’t really grow in height, but in widht instead, and make more leaves.
The second option is to support the leaves by use of a supporting twig. It’s better for use as a support appliance, because the stems are usually too fragile to be firmly put once they’ve shot out. Do NOT ‘glue’ them with cable ties or different solution because you’ll usually do more damage than help your plant. A simple support to lean against is usually more than enough to let them stand by themselves again, after only a few days. If they have come through after the first week or 10 days, the stem is usually strong enough to carry the seedlings by themselves, even if they get less sunlight from time to time.
As you can see on the pictures, the DutchFem Autoflower is using a skewer as support because she got not enough sun due to the Dutch climate on the windowsill. If you have the possibility to give them more sun by putting them outside (Every now and again) she will be happy with that. Again, you should pay close attention to the first 2 weeks, making sure they’re not in too much wind, because a young plant can’t take that either and will quickly fall over/break. A tiny bit of wind is no problem and will only stimulate her to make a stronger stem.
And every extra hour of sunlight will contribute to better growth and yield. It is a good idea to move them as little as possible, because they don’t want to be disturbed during growth. The plants are already 3.5 weeks old and 10 and 12cm tall and are starting to make their second set of leaves. We will give an update with photos of the results of our Windowsill Grow experience regularly
