If your substrate drains poorly, excess water in the soil will prevent your seed from accessing oxygen, and it will encourage fungal growth. You can improve the water drainage of your soil by adding some perlite. Also, always make sure your planting containers have holes in the bottom for water to drain out.
Unless you are using cuttings, growing weed starts with germinating your seeds. If your seeds don’t sprout, for whatever reason, your grow will be over before it even has a chance to start. But If you know the reasons behind germination problems, your chances of getting your grow off to a great start will greatly increase!
7. NOT ENOUGH MOISTURE
Just like food, seeds are living organisms that need to be stored properly, otherwise they’ll degrade, die, or won’t germinate. When storing your seeds, keep them away from light, extreme temperatures, and humidity. A dark cupboard with stable temperatures is fine. For long-term storage, place seeds in a sealed container and store them in the fridge.
While tap water may be okay for more mature cannabis plants, it can be a problem for seeds and seedlings. Tap water contains chlorine, fluoride, and salts that can be detrimental to healthy growth and may even prevent seeds from sprouting altogether.
Seeds don’t need light to germinate. In fact, too much light can decrease their likelihood of popping. You only need to worry about providing light once your seedlings actually emerge from the soil. But make sure to start with low light intensity before gradually increasing over time.
Jiffy's, peat pellets, and other types of starter plugs with an alkaline pH inhibit germination in cannabis seeds. Some substrates such as coco coir may also be pre-fertilized and have a high EC (salt) level Untreated coco coir contains toxic levels of sodium and chloride. Or they could have been treated with fungicides and pesticides. If you have used a particular product with poor results you should stop using it and switch to rockwool or soil.
We work with distributors who enjoy the best reputation in the industry for professional storage and service. Our resellers are supplied by us directly or through our distributors. Although we make an effort to identify any black sheep in the cannabis seeds market it is impossible for us to monitor resellers all the time.
If you are new to cannabis growing it is not advisable to start with hydroponics. Don't make your first cultivation experience unnecessarily complicated! In hydroponics you have to constantly monitor EC and pH, choose the correct nutrient formulas and feeding schedule, clean and flush your system, invest in expensive equipment, etc. If you are insecure about germinating and growing in rockwool or other hydroponic substrates, switch to soil or start with a small test group to gain experience.
Please read our Germination Instructions before germinating your Mandala seeds. Due to the high quality and fresh stock of our seeds we advise against soaking the seeds in water or germinating in paper tissue. Germination results will vary when pre-soaking seeds. Fresh seed stock can germinate under these conditions, but not always. Most often, only pre-germinating in moist paper tissue works for fresh seeds. But this is also not full-proof and should only be done if you have enough seeds to spare.
The major cause is lack of light. The seedlings are stretching in search of light. This leads to elongated and weak growth. Give your seedlings as much light as possible. Move them closer to the lamp. Put them under an HPS lamp if available. If you are growing near a window move the plants to the sunniest spot or supplement grow time with a lamp. Outdoors you should also provide as much light as possible. Support the seedlings with a stick or looped wire while they regain strength. As soon as they have sufficient light they will grow vigorously.
