If growing outside, some growers prefer to germinate seeds inside because they are delicate in the beginning stages of growth. Indoors, you can give weed seedlings supplemental light to help them along, and then transplant them outside when big enough.
A couple big drawbacks, though: Autoflower strains are known for being less potent. Also, because they are small in stature, they usually don’t produce big yields.
How weed seeds work
Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.
You might also find a mature seed that has been physically damaged through poor handling, like rough trimming. In those cases, it probably isn’t worth the effort to try and germinate the seed.
Ask yourself a few questions to decide if it’s worth the time and energy to grow the seed.
Starting from seed is a remarkable journey. Understanding the biology is one thing, but comprehending how a little miracle bean can turn into a gigantic tree that can affect your body and mind is nothing short of an evolutionary miracle. Or rather a co-evolutionary story of plant and human.
To accelerate germination, you are going to want to soak your seed in a small container with lukewarm water and place it in a dark and warm place for 12-24 hours, but no longer. By drenching the seed, it absorbs the water thoroughly, activating the germination process. Doing this also helps to loosen the shell as it becomes a little softer making it easier for the embryo to crack it open. When your seed sinks to the bottom it is ready to be planted, and sometimes the seed will pop out a small taproot. A seed can still be planted though if it does not sink.
“Don’t judge each day by the harvest you reap but by the seeds that you plant.”
For young plants, it’s best to use bottled water as it has no chlorine added. If using tap water, let it sit for 24 hours before watering to dissipate any chlorine. Chlorine can also be eliminated by boiling for 20 minutes. Under normal conditions, after soaking your seedling pellet, it should contain all the moisture your plant needs before it comes above ground. As it grows, it will only need about a shot glass worth of water at most per week to keep the medium damp. Seedlings don’t drink a lot of water, which makes sense given their size. Your plant will do better in a growing medium which is damp. Overwatering is just as deadly as drying out.
Seedlings require a medium amount of light in which it has enough to grow but not too much light that it gets burned. Leaving your seedling in direct sunlight will cause the leaves to curl, while too little light will cause the seedling to stretch. If growing outside, seedlings want to see a direct light source to stop them stretching. If inside, a sunny windowsill with more than half a day of sunlight works wonders. Otherwise, 18 in away from a growing light works excellently. Your seedling should not stretch more than 6 in at most. We’ll cover lighting in more depth in a later blog.
Perhaps the most exciting stage, your baby will typically come above ground in 1-2 weeks. As your seedling comes above the soil, its shell might take a few days to fall off. It’s best to leave it alone, nature has the job covered. If it does not come above ground after about two weeks, the chance of success is dramatically reduced, and it’s best to try again. Even the best seeds have an 85% germination rate. When your seedling comes above ground, it is going to want to see a direct light source.
Cupboard, grow tent or dedicated grow room. Directly in the soil or in pots outdoors. Even in a companion planted garden your marijuana will need to satisfy all these needs to grow well and supply you with high-quality resin soaked nuggets.
HPS (High-Pressure Sodium) and MH (Metal Halide) lamps are traditional types of grow lights. A 1000W HPS with reflectors can efficiently light a 1.5 x 1.5-meter space and provide excellent growth. Similarly, a 600W MH lamp will light the same sized space and give you world class flowers at the end of the grow cycle. The heat factor generated by these lights must be considered. If not exhausted efficiently your grow space will quickly become too hot for healthy cannabis growth.
So, you have come to the decision to grow your own cannabis. Well done! Soon you will be part of a rapidly growing culture. The phenomenon of homegrown marijuana that is sweeping the world.
Step 3: Lights For Indoor Cannabis Growing
OUTDOORS: Cannabis grows rapidly once the daylight hours start to increase during spring and on into summer. Unlimited root room and good genetics can see a plant grow to three or four meters during the vegetative phase.
STRAIGHT INTO THE MEDIUM: Place seeds directly into your medium, this way you can avoid any transplant shock. More often it is easier to germinate in a small pot of your chosen medium then pot on to the garden or bigger pots.
Understanding the fundamentals of cannabis growing is a good place to start your marijuana growing journey. Making informed decisions early will maximise your end yields. These seven basic steps will give you an excellent knowledge base to become an expert marijuana gardener.
TEMPERATURE: Cannabis is a very hardy plant and can survive cold and heat well. Just like you or me though, it can get stressed and not function well in the extremes. Cannabis can freeze or boil to death. It can stop growing or go into stasis. It will go into survival mode if the temperatures are too high or too cold for too long. Twenty-seven degrees centigrade is the accepted ideal for vigorous cannabis growth. Indoors this is easy to achieve with fans, air conditioning units, heating and cooling mats. Lights will certainly generate heat that needs to be vented.
