Training is any method you use to control the growth of your plant.

Topping is probably the most common form of training(for canabis).
Topping is high stress training. Cutting the main grow stem off stresses the plant and causes it to redistribute its hormones to other grow tips resulting in the multi cola plants. Low Stress Training (LST)

There is little if any recovery time because you are not damaging the budsites of your plants. When you tie the top grow tip below the rest of the plant the plant has the same reaction as topping and the axial growth tips are redistributed. The key to LST is to create a horizontal plane of buds so that they all get the same light and grow at the same rate. You end up with a bush of many colas instead of the traditional christmas tree bud plant with one main cola. There are many ways to LST using steaks, chicken wire screens are common, many other I probably dont know about. First step is to get a large pot the final size you want your pot and put a bunch of screws arround the lip of the pot I used 8 screws. These are the tie points for your training Second Step.

This next step is CRITICAL!!! I cannot stress this enough. This is the countertie. It is used so that the bottom part of your plants stem stays straight and in place. Without a countertie you are likely to uproot your plant because training usually occurs when there about a month or so old and not extremely established. Its simple just tie a piece of twine from one of the screws arround the bottom of your plant. Make sure that your twine is tied above the first leaf pair so that it doesnt slip all the way down to the bottom of the plant. Third Step.*

The next step is to tie the main growth tip down so that the plant will release hormones that cause all the other growth tips to start functioning like the main cola.* I use a simple overhand knot and tie my twine UNDER the highest set of developed leafs. Once again you need to make sure that the knot doesnt slip off of your plant. Then i tie a slip knot arround a screw. I use slip knots so i can just tighten the string as the plant grows. You can retie it everytime but im super lazy and that wouldnt cut it.One last comment....one thing that wasen't mentioned above was the ability to tie shade leaves out of the way to get more direct light to bud sights*

Screen of Green (SCROG)
The screen of green (SCROG) method is also used when height and wattage are a consideration. A screen, usually of netting, screenwire or chickenwire, is attached at a desired height above the plants. This allows the growing marijuana plants to begin to grow horizontally after reaching the height limit, thus keeping the canopy, or height, at an even level, which allows consistent light penetration into the growing plants. Many growers have a consistent high yield using this method.*

*Sea of Green (sog)
Sea of Green Is the theory of harvesting lots of small plants, matured early to get the fastest production of buds available. Instead of growing a few plants for a longer period of time, in the same space many smaller plants are grown that mature faster and in less time. Thus, less time is required between crops.

This is important to you when the electricity bill comes each month. One crop can be started while another is maturing, and a continuous harvest, year round can be maintained. 4 plants per square foot will be a good start for seedlings. 1 plant per square foot will allow plenty of room for each plant to grow a large top cola, but will not allow for much bottom branching. This is OK since indoors, these bottom branches are always shaded anyway, and will not grow very well unless given additional light and space.

The indoor grower quickly realizes that plants that are too tall do not produce enough at the bottom to make the extra growing time used worth while. An exception to this rule would be if it is intended the plants are to go outside at some point, and it is expected that the light/shading issue will not be a factor at that point.The plants, if started at the same time, should create what is called a "green canopy" that traps most of the light at the top level of the plants. Little light will penetrate below this level, since the plants are so close together.

The gardener is attempting to concentrate on the top of the plant, and use the light and space to the best advantage, in as little time as possible. Use of nylon poultry fence or similar trellising laid out over the green canopy will support the plants as they start to droop under the weight of heavy fruiting tops. Stakes can be used too, but are not as easy to install for plants in the middle and back of the room, where reach is more difficult. It's easy to want big plants, since they will produce more yield per plant, but it's usually better with limited space to grow smaller plants that mature faster and pack into smaller spaces.

Sea of Green was developed in Holland. Instead of fitting 4 large plants in that small room, fit 12 small ones on a shelf above 12 other small plants. These plants take only 3-4 months to mature from germination to ripe buds, and harvesting takes place constantly, since there is both a vegetative and flowering area devoted to each, with harvests every 45-60 days. It's not the size of the plant, but the maturity and quality of the product that counts. Twice as many plants grown half as big will fill the grow space twice as fast, so harvests take place almost twice as often. Get good at picking early flowering plants, and propagate only those that are of the best quality. 6" square containers will allow for 4 plants per square foot.

You may also gauge by the size of your growing tray (for passive hydroponics); I like kitty litter boxes. ($3 each at Target) Planted 4 per square foot, (for vegetative seedlings) a 12 sq. ft. closet will hold 48 seedlings on one shelf. In my case, I use 4" rockwool cubes that fit into kitty litter pans @ 12 cubes per pan. I can get 5 pans onto a 12 sq. ft. closet upper shelf, so that is 60 seedlings on one small shelf! For flowering indoors, 1 plant per sq. ft. is a good rule of thumb for SOG.

If less plants are grown in this size space, it will take them longer to fill the space, thus more electricity and time will be used to create the same amount of product. If more than one plant p.s.f. is attempted, the grower will soon find that plants thus crowded tend to be more stem than bud, and the total harvest may be reduced, so be cautious. It's good to avoid "topping" your plants if you want them to grow as fast as possible.

It's better just to grow 2 or 4 times more plants, since they will produce more, faster, in the same space. Also, "training" plants with twist-ties is a great way to get them to bush out a bit. Just take any type of plastic or paper twist tie and wrap it around the top of the plant, then pull it over until the top is bent over 90-180 degrees and then attach this to the main stem lower on the plant. Do this for one week and then release the plant from it's bond. The plant can be trained in this fashion to take less vertical space and to grow bushier, to fill the grow space and force lower limbs to grow upward and join the green canopy. This technique takes advantage of the fact that if the top is pulled over, it creates a hormonal condition in the plant that makes it bush out at all lower internodes. Sea of Green entails growing to harvest the main cola (top) of the plant. Bottom branches are trimmed to increase air flow under the "blanket" of growing tops. Use them for cuttings when you need more clones.** *

Topping (fim)
Some marijuana growers will take a pair of clippers to the top of their plant just above the last branch formation during the third or fourth week of vegetative growth. The top is removed by shearing it away at the stem. What happens next is that the main stem splits off in two or more directions, creating a V-shape at the top of your plant. The end result after flowering is two or more top colas instead of one. Now, two top colas instead of one does sound appealing and some growers have even managed to force a plant to grow more than six top colas using this method.

Unfortunately this topping method of pruning doesn't always lead to better results.Depending on the strain and the growing environment, the 'topped' plant may produce two small top colas instead of two big ones. Also, each strain has a threshold for bud production that cannot be improved upon because it is a genetically predetermined factor. On the other hand, some plants when fully grown without topping do not reach their threshold. The strain Blueberry is a good example of this.

If you grow Blueberry without topping you won't achieve maximum bud production from that plant, but if you top the Blueberry, you will. Other strains aren't so flexible and the two top colas will simply share the same volume of bud that a single cola would have produced on the same strain.It's advised that you keep in mind that pruning for yield using the topping method is strain-dependent and experiment carefully with this pruning method. Do this with 2 out of 10 plants in every grow. You'll find in time that during this vegetative prune you will be able to shape your plant.

Plants are generally pruned three to four weeks into their vegetative cycle, but can be pruned sooner or later or more than once.Pruning during flowering is not advised as the plant will be forced to divert its energy from bud production into branch and leaf production. This results in a slower rate of bud growth. For optimal growth finish your pruning well before flowering.

(fim) is a form of topping where instead of topping the plant where the new growth is and the plant v's off leave a lil remaining instead if a clean cut and the plant will grow multiple tops I have seen as meany as 8.The increased number in tops is due to the the topps that are left have more growth hormones and split off instead of two tops you get multiples*

Super Cropping Technique
Supercropping is an easy growth - training method for marijuana growers. This is simply cutting off the top of the main stem several times during its vegetative growth, leaving approximately 10% of the stem intact each time. This method induces the plant to generate the growth of additional side shoots, which in turn increases the overall bud production. This is a favorite method of many growers, due to the almost - guaranteed increased yields.

Super Cropping: By taking a branch between your forefinger and thumb you can gently crush the branch, causing it to develop multiple branches above the crushed area. You must crush it on the correct side or risk breaking the branch. Just squeeze lightly until you feel the branch give, then let go. If it gives easily then you have crushed it on the correct side. If it is hard to crush and the branch splits then you have chosen the wrong side.

Practice makes perfect with Super Cropping.Super Cropping should be carried out during the second or third week of vegetative growth and does stunt the plant.You should also note that plants that are Super Cropped can remain in the vegetative growth stage for twice as long as normal but the end result is a very bushy plant with multiple node regions that should all produce bud. Many growers have thrown Super Cropped plants away because they believed that the plants were not flowering in time. If you Super Crop your plants make sure that you have the patience to wait until the process is finished which — usually about four to six more weeks of vegetative growth.**

Good luck and happy growing:ganjamon::rollit:

I just put two plants in scrog, they were in 5 gallon hard pots so I potted up to 10 gallon fabric pots (600 watt was potted up 2 weeks before & 400 watt only a few days before 12/12 change), past two weeks slowly cut time back then changed MH bulb to HPS & changed hours to 12/12 time two days ago, and they both have white pistils with tiny budding beginning. Do I count weeks of flowering beginning light 12/12 change? IDK what they are so how will I know when to flush for harvest? Flush at 7 weeks from light change?

. 60 watt, LST now in scrog. I cracked the base of my plants while training and they are a little over 2" around so during flowering should I zip tie the base?
