We frequently get asked for tips about growing. Our first answer would be to buy The Green Harvest Grow guide off our site (only £9.99) This guide is only a breif introduction to growing. The book is great for begginers so it's worth the money. Remember it is illegal to germinate seeds in the UK and other countries, this info is solely ment for those of you who live in places where it is legal to grow marijuana
Germinating / sprouting
So, you have your beans in your hand. Now you are wondering what you are gonna do to get these to start growing. If you have purchased seeds from us then you can be sure that they are all fit to attempt to germinate since they have been through a screening process already.
Some people like to germinate the seed using methods such as the paper towel method before they grow the plant. This is to ensure that the seed(s) get off to a good start . But it is not really necessary to do this unless you have a large amount of seeds for your area (50-100+ seeds). If you only have a few seeds then you can plant them right in the soil.
To germinate in a paper towel simply place the seed between to dampened pieces of the paper towel. Next, place the seed/towel combination into a Tupperware container or plate. Set the container on top of a computer monitor, refrigerator or propagation pad and wait until the seed cracks and you see a tiny white root tip start to emerge from the seed.
After you have germinated the seed you will see a little white root sticking out of the split shell. Dig a small hole in the soil (I like to use the end of a pencil to make the hole). When planting the seed(s) or sprout be sure to only go down 1/4" to 1/2" and drop the seed in. Make sure that the root or pointy side of the seed is pointing down when inserting into the soil. Fill over the whole with soil, then keep the soil moist but not damp/wet with some water. You should provide at least 4" of vertical space for the tap root to grow down. Place one seed each in a 20oz+ cup or a one gal pot then place your pot under your lights. Start with a 24/7 light cycle (24 hours on, 7 days a week). You should see sprouts within 2-14 days depending on your individual conditions and the method you used. For quickest results try and keep the temperature in the mid to high 80's (F). You will see slower germination rates but lower temperatures are acceptable as well (70s), this will simply increase the amount of time it takes to germinate the seed.
The sprout will emerge first with the 2 seed leaves. These leaves are small, smooth and round followed by a set of single bladed, serrated leaves known as the first leaves. The height of your light from the sprout will depend on what kind you are using. If using florescent lights, they usually run cool enough to put them within 1-2 inches of your sprouts. If your going with a HPS or MH type of light, they get hot, so you won't want them too close. A good way to test a light is to put your hand between the plant (or in this case soil) and test how hot it is with your hand. If it's uncomfortable for your hand, it's too hot. Raise the light up until you reach a good temperature. These type of lights will also dry your soil out fast, so keep your eye on it. Once your light is set and the leaves start coming in you now are on you way to growth stage.
Once you see the plant break though the top of the soil (it should take from 1 day to 1 week) you will see two small round leaves. Your plant will grow up a few inches with the two leaves getting a bit bigger and new leaves starting between the two round ones. Your stem will probably look white, green or even purple at this stage. The color depends on what strain of plant you have. It's advised that you refrain from giving your plant fertilizer during the first stages of growth. These stages are quite delicate, it doesn't take much to make a fatal mistake. Remember though out the whole live span of your plant, like most other things in life, the more things you have going on at one time, the more likely for a problem to arise. Your best bet is to keep things simple.
Once your new sprout starts producing leaves, you are in the vegetative growth stage of the plant. Only water when the soil is dry all the way to the bottom of the container it is growing in. You can check by sticking a finger through one of the drain holes in the bottom of the pot to feel how wet the soil is, or by using a water meter. Perhaps the best method, however, is to wait for the plant to tell you it needs water. The leaves will start wilting slightly and the plant generally looks "thirsty". The reason this method is preferable to others is twofold – one, you are assured of not overwatering, and two, allowing the soil to dry out completely stimulates the roots to grow as they search for water. More roots = a bigger, stronger plant = more & better buds.
Probably the most common error for new growers is overwatering. Over watering will cause the plant to grow poorly, and if continued will lead to root rot and eventual death. Be careful if you are starting out with a large pot. If you water a small plant too much in a large pot, the plant may not be able to soak up all that water. It may look dry on top, but you might end up having mud on the bottom of the soil. This will cause root rot on your plant and is very unhealthy. A plant that is not watered enough is much more healthy then a plant that is watered too much. It's also harder to recover from over watering then under watering.
Since you have your plant in the 24/7 cycle let the plant grow for as long as you like. A plant may double, triple even quadruple its' height when flowering. Sativas can stretch up to 4 times there height and Indicas generally double in height. Some strains call for up to 8 weeks of vegetative growth. Your height, yield and potency will all depend on the strain and the way it was grown. As our aim is for bud, and lots of it, we will try and avoid massive plants unless we have the light to provide them with, otherwise we get a plant with huge stems, and only bud at the top 9 or 10 inches.
Remember, you can only get "bud" from a female plant. So you want to focus your efforts on the female plants. In order to find the sex of the plant, (for diagrams see the Green Harvest Grow Guide!!!) get a light timer and put the lights on a cycle of 12hours on and 12hours off. Having a light timer is much easier then doing it manually and is much more accurate. Make sure your plants get the complete 12hours of darkness during this stage. Any light interruption may prolong your sexing results for days or even weeks. Your flowering stage may take 2-3 months. You need to keep them on a constant cycle and remember to have complete darkness during the 12 hours of no light. Any interruption may cause reduced yield, potency, or extended harvest.
Cannabis is harvested when the flowers are ripe. The best indicator of ripeness is the color of the flower's pistils. Over the course of the flowering period, these pistils begin to die and, depending on the strain, turn different shades of brown, orange, and so on. Many cultivators choose to harvest when 60-75% of the pistils, or 'hairs' have changed colors. Optimum harvest times will vary widely with each Cannabis strain, so the best way to find that perfect harvest time is to experiment! Try cutting buds off during different times of flower (one at 6 weeks, then one at 7 weeks, etc.) to determine which time period suits you best.
