Advanced Indoor Soil Based Grow Methods

New ways of improving your plants yield have crept up over the years or so and some of them have become quite popular. The three most common new types of indoor growing are SOG, ScrOG and Cabinet growing. These are basically ways to grow seriously large top colas.

These methods do not have to be soil based, one can use hydroponics instead but soil is generally the most widely used medium with these set-ups.

The idea behind these methods is that the bottom branches of indoor cannabis plants do not catch much of the light cast from the HID and are not that good to smoke either because they are fan leaves. So why not create an apparatus that concentrates on the top part of the plant. In most cases the cola, is going to produce the most bud so why not try to get that part of the plant to grow really big. So along came the idea of SOG, which is also called Sea of Green.

A SOG set-up can be any size but must maintain a certain overall shape. First of all you need to grow some plants normally first. Wait until you see flowers and then select the nicest female you can find. Take cuttings from this female mother plant and grow the cuttings out until they have roots. When you do take multiple cuttings try create as many plants as you can fit into your grow set-up. In SOG grows we are looking a 1 plant per square foot or even one plant per 0.10 square feet. So that should be a good estimate as to how many clones you will need. Now, we want to look at pots here first. What we really need are tube shaped pots or pots that have a longer depth than width. You can make these yourself or buy these pots in the store. All we want to do is pack in as many pots with plants as we can into the SOG grow chamber. It is just a big cluster of pots with clones. The clones are planted all at the same time. No more new plants are introduced into the SOG grow room. When they have reached your desired height (keep it small), they should be flowered. Because the clones have been taken from a mother plant, the clones will carry the age of the mother plant with them. Since we took them from a flowering mother they will start to flower as soon as we start 12/12.

The final harvest result will be a full canopy of bud, hence the name Sea Of Green. Because you are using clones you only have to grow the clones out for the remainder of their flowering times. This means you can have a large bud quantity turnover ever 2 months.

This is like a SOG (Sea of Green) grow except fewer plants are used in conjunction with a screen to fill the grow area out with heavy top colas, hence its name - ScrOG (Screen of Green).

This screen is simply a large wire mesh put between your light and the plants (Figures 8.1 and 8.2). Again clones from a female plant are used like in the SOG method, but we allow at least 1 square foot per flowering plant in the ScrOG method.

The plants are not flowered until as such time as they have covered the entire mesh with green. As the plants grow up through the wire mesh they are trained and worked around the netting to form a very even canopy. The top colas and side branches are all trained under the screen.

There are many variations of the above two methods. They all still contain the same principles. SOG and ScrOG's were originally set-up to get the most out of poor quality fluorescent lights. Today's growers, since HID's came along, using a 600 watt HID bulb have literally taken these set-ups to a new level.

The veteran fluorescent user would line the roof of the shelf or the box with fluorescent tubes to try and get the most out of their grow with this method. Now with the HID lights they can really push their buds to the limit. Some people even grow top colas that are the size of soda bottles or large corncobs!

RealHigh is a ScrOG lover and has been growing ScrOG style for some years. He has added a bit to the ScrOG method through his experience with the process. This should help you understand more about the ScrOG method and what people have learned with this new technique.

This is like a SOG (Sea of Green) grow, but a screen is used to train the plant to grow horizontally creating a canopy of buds beneath the light. The screen is simply 2" chicken wire, or 2" nylon poultry fencing, or one can use hooks and 20 lb. fishing line to make their net.

The screen is at a set height above the plant medium. This height varies from 8" to 24" depending on the size light used to grow with. The light should be hung by chains and adjustable so that one can raise it if needed.

Clones are used again like in SOG style, because we do not want a hole in the canopy were a male was removed. This is why we use female clones for SOG and ScrOG grows. It does not take as many plants for ScrOG grow as compared to SOG. One should allow at least 1 square foot per flowering plant in a ScrOG grow.

This method also takes anywhere from 1 to 3 weeks longer per grow because we will be in a vegetative stage longer than a SOG grow.

The plants are trained to grow horizontally under the screen until they are 2 weeks into the flowering cycle. At this point you let the tops grow vertically through the screen. One should always train the main growing tops to the outside of the screen. They always grow the tallest, and we want the tallest to be on the perimeter of the screen. As the tops grow vertically, push the large fan leaves down under the screen, allowing the light to get to all the developing bud sites. If leaf growth is excessive, one should first cut the finger in half making a shorter leaf and allowing light to get to the bud site. Leaving half the leaf on the plant still allows it to make energy for the plant to grow. Taking a whole fan leaf away in one go can stunt growth.

In a week take off the rest of it. Some do not remove leaf at all, but I do it to help with air movement, reduce chance of mould or fungus, and to allow light to penetrate the bud sites. Just remember to remove a little at a time if you do remove leaf.

At this point flowers are forming and growing vertically creating a carpet of bud above the screen. Now we go below the screen and remove all the lateral branches and stray bud sites. The canopy has thickened up enough now that light is blocked from reaching this lower growth. It is only sucking away your plant's energy from the buds under the light. Remove all branches that have not made it to the screen and the stray bud sites. We want the plant to concentrate all it's grow energy on the developing flowers above the canopy.

The main 3 differences between a SOG and ScrOG grow is the number of plants grown, the screen, and the slightly longer grow cycle of the ScrOG. Both methods can be done under the same light and in soil or with hydroponics. There are many variations of the ScrOG grow, but they all contain the same principles. There are the V-ScrOG, Stadium ScrOG, Flat ScrOG, and the Cylinder ScrOG grows in today's homes. I think you can picture what these look like. They work the same way but just have a different shape.

One of today's strains has earned a place in the ScrOG garden and this is C99. One will find a pure indica or indica dominant cross will produce the best in a ScrOG grow. A good ScrOG grow will average 2 ounces of bud per square foot of screen, but one can not expect this the first few grows, for it takes proper timing and the correct strain to accomplish this.

ScrOG was originally designed for grow area's limited in height and fluorescent lights were used to light the grow area. Today's growers are using HID (High Intensity Discharge) lights for growing ScrOG. They have taken it to the next level with these lights and are generating great results.

Today's grower is always trying some thing new to better production of their favourite plant.

So there we have RealHigh explaining to us how he has worked with the ScrOG system. As you can see he has added much more to the basic ScrOG than we have mentioned. All this comes with experience, practice and experimentation.


To define this is going to be no easy task. A cabinet can be your hot press, small closet, an old refrigerator, a box, a press, or a simple cupboard will do. The grow area is usually small and can accommodate 1 to 4 plants at a time. The idea behind a cabinet grow (Figure 8.4) is to keep a cycle of plants growing at all times. There are three things a cabinet needs to get started, and these are:

-The Cabinet -A Light

-An air vent with fan.

Most people simply set up their lights so that it is adjustable.

Figure 8.4 - A simple cabinet grow by X3n0.

They do this by using adjustable chains or a spring-type cord. A large hole is made in the unit to allow some air to get in. Another hole is made to allow air to escape. A fan is placed in one of the holes that will extract the hot air which is being generated by the heat from the bulb. This vent and fan would be near the top of the cabinet near the light. Hot air rises and that is why it is placed there up top. The intake hole is on opposite side of grow area and can have a fan in it also. This fan is generally moving a bit quicker than the extractor fan to allow a fresh supply of air to circulate before leaving the grow room.

The walls are painted flat white or Mylar is hung for reflective purposes. The plants are usually placed in separate pots and go through their entire life cycle within the cabinet environment. Clones are taken from the plants and placed either on a second shelf in the cabinet or near a window in your house. Some people have made a small compartment in their cabinet for clones and germination. This can be any size, but is kept small because you only want to just keep the clones alive. This small compartment will probably have one or two fluorescent lights in it for the clones. It would be best to keep the compartment at the top of the grow chamber near the exhaust fan. You do not need an intake fan for these clones unless it is a big set-up. A simple hole in the side will allow the plants to breathe. After the harvest, these clones are put into the grow room and the process is repeated. It is a Perpetual Grow. The legal term is a Marijuana

Factory. You can harvest bud every 30 days if you have the right strains. Your light can be air-cooled in a few ways. The most common way is to mount a 4" dryer flange on the hood and link from the hood flange to the exhaust fan flange with a 4" dryer hose. A fan can be mounted on the hood also.

Figure 8.5 - This is a picture of a typical air-cooled system that can be purchased in most grow shops that sell grow lights.

Growing Marijuana Indoors Soil


As you can guess all of the above grow methods can be shaped to suit the grow room.

Many a cannabis cultivator have turned entire rooms into a ScrOG or SOG grow. Size is totally up to the grower. For those who are happy with 4 ounces of dried bud every month a small SOG or Cabinet grow is the way to go. For those who want a bigger yield to last all year then a large ScrOG grow may be considered. Many a 5-ft. x 5-ft. ScrOG grower have delivered 30 to 50 ounces of Marijuana every 2 months. When conditions are at their optimum level this can be achieved.

An expert's indoor grow room would look something like this. 14-ft. x 24-ft. area x 9ft height. Several vertically suspended HPS lights would hang from the ceiling. The roof, walls, and floor would be covered in reflective material like flat white paint and Mylar. All lighting fixtures would be met at a junction box on the wall. Ballasts would also be attached to the wall. The plants would be placed on the ground in large container buckets inter spread between the lights hanging down. The room would also be completely light proof.

Multiple air ducts and extraction fans would take the hot air out and pull the fresh air in. An Ozone generator would be in place to kill the smell and cannabis odour. Other items may be in place such as a CO2 generator, electrical generator, and even a light mover like a Light Rail III. A Light Rail is a horizontal light mover and there is a ASun Circle' that the lights suspend from that move the lights in a circular pattern. This allows fewer lights to be used in covering a large grow area like this one.

Sun Circle Light Mover

That is about the bones of what a professional grow room would look like.


The objective of the perpetual grow is to keep most of the room flowering at all times. This means that while your plants are flowering you will have an equal amount of plants in the vegetative growth stage. So in essence, half the grow is in its vegetative stage and the other half is in its flowering cycle.

As with most grow rooms, the grower will learn to make the best use of his/her grow space. The room will become an intense hobby area and a most rewarding one too. In time the grower may even begin to learn more about plant genetics and start to develop some strains of their own breed and stock. Soon the grower may find himself or herself entering competitions or even producing some of the finest seeds available on the market. As you know seeds sell between $20.00 to $150.00 for 15 seeds. A breeder could soon find their hobby turned into a nice little income maker.
