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.*





Cannabis Growing Guide 5/6 – Male/Female

28 01 2009

Cannabis plants are either male or female. The male plants produce pollen which pollinates the flowers of the female plant, which once pollinated, produce seeds. If the female plant is not pollinated (if there are no male plants nearby producing pollen), the flower/buds continue to develop and produce THC. Female plants which are not pollinated are referred to as sensemilla (without seeds).

Usually 40-50% of the plants are male.

A female can either generate a large seedless bud, a large bud with a few seeds, or a large bud that is almost totally seeds. The first case is achieved by removing all the male plants before any of their flowers open. The second case occurs when a few male flowers have opened but you remove them before any more open. The third case occurs when you miss-time the flowering of the male. This can be devastating if you have big female plants because you could loose 90% of the smokable herb to seed production.

The spotting of males is one of the most difficult of things to explain to a person that`s never grown since it really takes careful attention to how the tops of male plants look at this stage of development. Even experienced growers will be unsure at times and will have to wait till the next visit to be sure. When a male enters the stage of flower development, the tips of the branches where a bud would develop will start to grow what looks like a little bud (little balls) but it will have no white hairs coming out of it. Females will have no balls and will have small white hairs.

Male is on left with cluster of balls and female is on right with wispy white hairs.

Difference between Male and Female Cannabis plants

Difference between Male and Female Cannabis plants

Males are often, but not always, tall with stout stems, sporadic branching, and few leaves. Males are usually harvested except those used for breeding, after their sex has been determined, but before the pollen is shed. When harvesting, especially if close to females, cut the plant off at the base, taking care to shake the male as little as possible. This helps prevent any accidental pollination by an unnoticed, open male flower.

Tip for beginners: Buy feminized seeds! This way you will only get female plants.

Feminized strains tested

22 08 2008

White Labels’ Northern Lights strain achieved first place in a test conducted by the Spanish Cannabis magazine Cáñamo.

Cáñamo conducted a grow test of 23 feminised strains and published the results in their August issue. Ranking was determined by the yield of bud produced per plant.

Northern Lights´ first place is especially noteworthy, as her yield was double the average weight of the tested varieties and around 30% greater than that of the nearest runner-up.

White Label´s X-Haze achieved 18th place in this competition, which is a very respectable result for any Haze variety.





Feminised cannabis seeds from Sensi Seeds

24 06 2008

Sensi Seeds marijuana seedsSensi Seeds recently announced they are now also have feminised cannabis seeds in their product range. The feminised strains they are now selling are bred from 5 of their most popular strains.

  • BIG BUD
  • JACK FLASH #5
  • SILVER HAZE #9
  • SKUNK #1
  • SUPER SKUNK

In their press release Sensi stated the following;

The idea is extremely attractive (feminised seeds ed.) – seeds that produce only female plants are a novice grower’s dream, eliminating the practice of sexing plants in the first weeks of flowering as well as the need to devote limited grow-space to unwanted males.
However, until quite recently, feminised seeds did not perform as well in practice as they did in theory, with unacceptable tendencies towards hermaphrodism, irregularity and unexpected growth. Hence, Sensi Seeds did not offer any varieties of feminised seed for sale until they could be sure such seeds were up to their exacting quality standards.

Have a look at these new feminised Sensi varieties for yourself.
