I have read sea of green and the scrog method...but will someone comment on the BOG Method.....

Bog methods

Many people have been excited about the scrog method and have dreamt up all sorts of ways to expand production, myself included in the mad scientist crowd. The most common variation is the "bog" method.

Bog for "box of green", was first coined by Kunta and further developed by chthonic and several other growers. Added to the horizontal screen are vertical screens around the perimeter. Either additional plants are used at the edges, or the scrog field plants are grown longer, but either way, the additional foliage is allowed to grow up the outside of the vertical screen, taking advantage of wasted air space above the field. It also allows plants at the edge of the field to get into the circle of intensity from the bulb.

Imagine the light field as a circle sitting tangent to a horizontal line. Imagine your plant as a point on the line outside of the circle. How can the plant get inside the circle? By going up. You might equate this method to an "arena" grow in this regard. An extension on the bog theme is spiral bog, first coined by chthonic. In a spiral bog the plants are allowed to add considerable vegetation, which is trained around the box in a laid-down spiral, like this: //////. This method allows all the screen area to be densely filled with bud sites.

There are two ways to fill the vertical bog screens, as I mentioned. The first is to use more plants, which are added to the edges of the grow. When the horizontal scrog field plants are forced to flower, the plants on the edge are allowed to grow vertically like sea of green plants, the resulting growth being trained to the vertical screens. If the growth is too tall for the screens, it can be laid down at an angle, like a spiral bog grow. The advantage of this type of bog grow is reliability and speed, since the horizontal field is filled in exactly the same manner as in a normal scrog grow. The disadvantage is that the number of plants is increased to near plantlet-method sea of green levels.

The second method is use the same number of plants as in a standard scrog grow, or thereabouts, but to allow them to grow longer before forcing, around another two weeks of growth seems to be about right. This process is proving to be tricky for me, and I have so far failed to produce a fully successful extended bog grow. But other growers are having success, and the method is superior in theory. Here's what chthonic has to say about his experiences with 70 watt HPS lights:

"The quickest and most successful approach that I have found to train a bog grow is to lower the horizontal screen to within 6" of the soil and grow 2 plants per sq. ft. straight up to the vertical training screens. As it's a box driven by a 70-watt bulb, the height from the horizontal screen to the roof is only 12". The plants grow unhindered 18" from the soil up through a narrow band of the horizontal screen and onto the verticals until they touch the roof. Then they are laid down horizontally and trained in a spiral fashion /// around the vertical training screens. Spiral bog or s/bog. The cabinet is small; spiral training is the only way to direct the shoots so it just happens...

"The spiral training can go one of two ways. The entire plant can be bent over in one direction and trained along with the rest of the plants in a clockwise or counter-clockwise fashion around the vertical training screens. Or the plant can be trained as it naturally branched, trained in opposite directions along the vertical training screens."

Any method of growing should be analyzed not only for production over the space used, but also for production over time. Just for the sake of argument, let's suppose a plantlet-method sea of green method produces 1 ounce per ft., and the subject plant takes 60 days to complete its life cycle. That would be .017 oz. per ft./day. Let's suppose a scrog grow takes two weeks longer, 74 days, and produces 1 1/2 oz. That would be .020 oz. per ft/day, advantage scrog. Let's suppose than an extended bog grow takes two more weeks than a scrog grow, 88 days, and produces 2 oz. That would be .023 oz. per ft. day., advantage extended bog.

Note that it's possible to shorten the cycle by growing plants in a separate area for about three weeks and then adding them to the scrog setup. But most micro and mini growers don't have room for a separate growing area.

The "bog" term is subject to some debate. Chthonic believes that the term should be used for a box of foliage that surrounds a light held in a vertical position. Such a setup can be an outstanding way to get the most of out small security lights in the 70-100 range. But I think for a larger light, like a 150 or 250, it is necessary for the light to be in the normal horizontal position above the box. Personally, your author thinks that bog can be used as a general term to describe such a grow, and I don't really know what other term to use. Chthonic believes this type of grow can be referred to as an arena grow, but I've usually seen that term applied to free-standing plants rather than a box of screen. In my recent compressed grows using shielded lights, I coined the terms "h/bog" and "v/bog", stealing from chthonic's notation, but no one else has picked up on the lingo. Time will tell what terms become attached to these methods. Most people just use the generic term "scrog". Fair enough.

Finally, hollow screen forms do not have to be in the shape of square-cornered boxes. I've seen one grower using small HPS lights who shaped his screen into a deep bowl shape, with the light suspended in the middle. Recently I read posts on ADPC describing inverted V shapes. A single "correct" way to do this probably doesn't exist.

At this point, these methods are so new that every grow provides significant information. My advice to those new to the scrog method is to get a few fast, flat scrog grows under your belt first to get used to the process. But do add the vertical screens regardless, and capture whatever excess growth you can on the verticals, as there is no reason not to handle as much growth as you can.

Smokin you covered everything All I can do is add a few pics.
Here's a link to my bog after it was built. http://www.hempcultivation.com/420/s...threadid=14436

And this is the only pic I have of it in use. This is an early stage. I got about half of the sides filled before I found out that they were all males.
