The 10 Biggest Mistakes Growers Make

13 10 2009

Just thought we’d share some helpful tips on what NOT to do when growing cannabis:

culture cannabis, marijuana, how to grow

  • 1. Don´t Over water – Over watering kills weed plants. Water once the top few inches of the soil dry out.  Hydroponics is harder to over water because rockwool has such excellent drainage properties. As long as the rockwool cubes are not sitting in liquid it is virtually impossible to over water a hydroponic setup. A hydroponic setup could either be watered constantly as the drip method, or once to three times a day as in the flood and drain method.
  • 2. Don´t Tell People – Why? They will only be jealous. People love to feel important and that is why they will tell other people; because others will listen to them. – Keep it to yourself.
  • 3. Touch/kill Germinating Seeds – Please have some patience. It sometimes takes 10 days for a seed to sprout. The paper towel method is recommended but be careful  because you must handle the seeds when transferring them from the paper towel to your growing medium. This must be done with extreme care!
  • 4. Grow seeds from seeded weed – One of the greatest disappointments known to the growing man.

90% of what the final product will be is in the seed´s genetics and has little to do with the environment the plant is grown in.

Many get their hands on the seed and think they have a gold mine. They will probably grow something like this: hermaphrodites, tall late flowering females coupled with early flowering males. This is because the only pollen that could have produced the seed was from a hermaphrodite or a very stunted and late flowering male the grower did not notice. Unless you are prepared for possible disappointment don´t use “unknown”  cannabis seeds. This is why people buy seeds from seedbanks such as Sensi Seeds, White Label Seeds, Weed Seed Shop or Flying Dutchmen.

  • 5. Don´t Over fertilize -Fertilize after first 2 spiked leaves appear follow the label. DON´T FERTILIZE EVERY TIME YOU WATER!!! Start with 25% and work your way up!  Leach the plants with lots of pure water every 2-4 weeks.  If the leaves suddenly twist or fold under, Leach and Spray with pure water for several days!
  • 6. Don´t Under fertilize – Under fertilizing is less common but it happens. If you are one of those people that likes to give the plant just enough nutrients make sure you use a organic soil mixture with blood meal and bone meal or some slow release fertilizer with micro nutrients.
  • 7. Don´t Start Too Early Outdoors – For several reasons! If you are starting outdoors June 1 is perfect. But if I start earlier I will get bigger buds right? Probably Wrong! Its strange but usually true: Plants started in early spring will get big but they will take significantly longer to start flowering. This is because at the peak vegetative period they sense the light cycles getting longer and longer, until June 21. But they don´t realize that its time to flower yet. Finally in the middle of August the plant says “HEY” “time to flower already” and it produces buds in August and September or later they will be tall as trees but thinner buds due to the fact that the sun is not as strong in September. Now if the ganja plants were put out later, as soon as they get a foot off the ground they say “what´s going on” I am just in early veggie and the light hours aren´t getting longer in fact SHORTER” Then the plants go crazy and since the sun is so bright in July and August you get amazing 6 foot trees that are heavier than the plants started in April!!! in addition to finishing earlier the late started plants are not nearly as noticeable.

Indoors is the same for different reasons. The light cannot penetrate more than a foot or two. So flower when plants are a foot tall. If you wait longer because you want bigger yields, you will get smaller yields and wait longer for them.

  • 8. Don´t Start too Late Outdoors – Plants need atleast a few weeks growing time before flowering starts as the summer days get shorter.  Starting too late in the summer will lead to small and/or immature plants by the time the season ends (harvest time)
  • 9. Don´t Provide A Bad Environment – Always provide air circulation and fresh air even during the night cycle is fine. All the air indoors should be replaced every 5-10 minutes.  Humidity between 30-70% temp aim for around 75-85´ Even seedlings need a gentle fan to strengthen the stems.
  • 10. Don´t Harvest Too Early – We know its hard. You see the buds and resin forming at a rapid rate. The buds are potent and you feel tempted to chop em down! The only problem is that another 25% of the weight will form in 2 more weeks. Wait until the plants have totally stopped growing and the white pistils are at least 50-75% brown.

*NOTE: Outdoors if security is a factor make your own call on when to sacrifice the fields. Also take buds continuously in case of thieves.*





How to: Germinate Cannabis Seeds

How to germinate cannabis seedsWhat is the best way to germinate cannabis seeds?

Basically, you’ll need two saucers or plates and some moist tissue.

– Line the bottom of the first plate with a few layers of wet tissue and drain any excess water from the plate.
– Next, place your seeds on top of the tissue, allowing each seed as much space as possible.
– Place another few layers of moist tissue on top of the seeds, again allowing excess water to drain off.
– Lastly, cover everything with the second plate, upside down, to form a ‘clam-shell’ shape – this will create the dark, moist environment necessary for germination.
– Place the plates somewhere warm (21ºC) and away from direct light.

Your seeds are now on their way to germination.

– Check your seeds every day to ensure that the tissue does not dry out. Spray the tissues with water if necessary.
– Within a few days you should see the first seeds open and a root emerge. It is uncommon, but some seeds may take up to 10 days or even two weeks to open.
– When the first few millimeters of root have emerged from an open seed, you should then CAREFULLY (preferably with tweezers) transfer it to a small container of growing medium (soil or rockwool). Make a hole 2-3mm (max 5mm) deep in the medium, place your seed, root first, into the hole and cover over.
– Your seedling should emerge from the medium within 1 to 3 days.

What are the best conditions for seedlings?

Seedlings will benefit from a bright (though not, initially, under lamps or in direct sunlight), warm (21ºC) and humid environment. A propagator is the easiest way to achieve these conditions. A propagator may be bought or built. It is, basically, a box with a transparent top which allows light in but stops humidity escaping. The simplest form of propagator would be a waterproof box with clear plastic sheeting over the top. The advantage of shop-bought propagators is that they often have built-in heating and/or vents in the cover to allow humidity regulation. They also usually allow more light to reach the seedlings.

Place your propagator next to a window to give the seedlings light, but avoid direct sunlight for the first couple of weeks.

When can seedlings be put under lights / in the sun?

When seedlings have grown their second or third set of serrated leaves (not counting the round cotyledons that initially emerge from the seed) they are usually hardy enough to flourish in direct sunlight or beneath a grow-lamp (preferably metal halide or fluorescent tubes). Always keep your grow-lights at least 50cm from your seedlings.

When can I tell whether they are male or female?

Cannabis will only show its sex once flowering has begun. Cannabis begins to flower when it receives 12 hours of light and 12 hours of uninterrupted darkness in each 24-hour cycle. Once this light cycle (or photoperiod) is initiated, the first flowers should be visible within 2 weeks.

Inside, it is the decision of the grower when to alter the photoperiod and induce flowering. This is achieved by simply adjusting the timers on your lights.

Outside, the grower must wait until the natural daylight hours have decreased to 12 per day. Exactly when this occurs will, of course, vary depending on your locality. In Northern Europe it happens around mid-to-late July.

It is possible to induce flowering outside by allowing your plants 12 hours of daylight each day, then covering them or taking them inside. This must, however, be done every day without fail.
