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: Easy Hydroponic Growing

15 07 2008

Hydroponic cultivation need not be complex or expensive, and requires only a little more equipment than indoor growing using soil.

Hydroponic growing differs very little from soil growing. The plants grow and flower in the same light cycle and are fed the same nutrients – nitrogen, phosphorus and potassium (N-P-K,

plus micro-nutrients and trace elements). The main difference is that hydro plants root and grow in a neutral medium which, unlike soil, has no nutrients of its own.

Hydroponic nutrient is water soluble and is immediately available to the plants when applied to the growing medium, while organic nutrients must be broken down by bacteria in order to enrich the soil to which they are added.

Aside from the indoor basics of light(s), timer, fans and air exchange (all of which are required for indoor soil growing, of course), hydroponic growers will require two meters for testing the nutrient water they give to their plants.

  • An electrical conductivity or EC meter measures the amount of nutrient in the feed water and presents it as a simple number, allowing growers to be sure that they do not over-feed or under-feed their plants. Nutrient meters in different regions and countries may measure in other scales: TDS (total dissolved solids) or PPM (parts per million).
  • A pH meter tests the acidity/alkalinity of water. Cannabis prefers an acidic growing medium, so hydroponic feed water is usually lowered to around pH 5.8.
  • Most growers will also require a substance for lowering and/or raising pH. Tap water typically has a higher pH than ideal for hydroponic cannabis, so it usually must be lowered. Household products such as lemon juice or vinegar are sufficiently acidic to lower pH.

In addition, hydro cultivation will require a hydroponic growing medium, such as rock-wool (ideal for starting seeds and clones) or expanded clay-balls (a re-useable medium and an excellent second stage for plants that start in rock-wool), and hydroponic nutrient for the growing and the flowering stages.

In this diagram, plants are growing in rockwool slabs. The reservoir is filled with nutrient water, and contains a pump(attached to a timer) which delivers feed-water to the slabs several times per day.The slabs are inclined so that excess water runs off and flows back to the reservoir.
