As peepo know ive been doing my first scrog so i have been reading up a bit more the last few days so i thought i would post some stuff i found incase its any use to any of you out there.the postman.

What is scrog?

scrog stands for Screen of Green and describes the practice of growing plants indoors on a horizontal, vertical or otherwise shaped screen.

Why scrog?

The use of screens to control the shape of the plant allows the lamp to be placed closer to a greater number of bud sites-and thus increases yield.

How?

For a basic flat scrog, fix a screen, or mesh, between 8"and 12"inches above your plants. Grow them up to it then bend the stems so that the shoots are growing horizontally along your screen.
You can allow the shoots to grow through the screen, then weave them back through; or bend the horizontally under the screen and tie them in position.
When the buds begin to form you can then position them above the screen to form a canopy of the desired profile.

Various sizes and materials are used for the screen, most going for a mesh size of around 2" square. Garden centres/DIY outlets usually sell rolls of plastic fence/mesh. Chicken wire is sometimes used but the thin bare wire can cut into the plant stem.

Who?

scrog
growing is usually done by smaller growers using one or two lamps, as access to plants and comparitively high levels of maintenance will be impractical for the larger or commercial grower.

How Big?

The same light to area ratio that applies to normal growing also applies to a scrog: thats is slightly less than 1msquare for a 400w, slightly over 1m square for a 600w.

Method?

The aim of a basic flat is to get the buds, during the final ripening stage of flower, in a flat, level canopy. To achieve this you will need to put the plants into flower at the right time-so they eventually stretch to fill, but not overfill, the screen. Getting this right involves a degree of guesswork and experience-and will depend on the particular growth patterns of the strain that you are growing. It is often stated that to fill the screen with a Sativa 50% of the screen should be filled before switching to 12/12; and 75% for an Indica-although from personal experience i've found that using these guidelines has resulted in plants that were too big.

here's a bit more

There are a few other areas where scrog growing differs from conventional cultivation-one contentious issue is removing leaves and shoots. Many scroggers remove most, or all, of the growth below the canopy; this is to allow increased air circulation below the screen.

The canopy, when filled out, can act as a horizontal barrier across the growroom preventing adequate air movement and trapping stale, humid air below. Also, scrogging involves
growing the buds closer together than would normally be the case-both of these factors can increase the chance of mould, so along with removing leaves and shoots, a fan is often placed below the screen to move the air around.

It is also claimed that removing the lower shoots/buds concentrates growth in the upper part of the plant.

Variations

The screen can either be attached to the pots/hydro, to the walls, or be supported on a stand.
If they are attached to the pots, or small hydros, it may be possible to fit several smaller screens together whilst still remaining movable, or detachable. This is termed a 'modular scrog', the main advantage of this method being the ability to move the unit during the grow; a consideration for those who have both veg and flower rooms.

If the screen is fixed to the walls, or other immovable objects, then it will be necessary to arrange the pots/hydros in their final position at the beginning of the grow.

The grower also needs to be aware of the need for access to the plants during the grow and a fixed screen can make this difficult. Again, this is something to take into account at the beginning of the grow otherwise you may find that when the plants get big-you cannot reach them and things can get out of hand.

This may sound like waffle, or obvious, but access can be difficult even in small GRooms-eg if you have a room say 1m square with two or three fixed sides-its going to be difficult to get to the back once things have got going.
(on a personal note-when on crutches i got stuck on my back under a scrogfor a couple of hours until someone came along and pulled me out).

Canopy profile

The profile of the screen does not have to be flat. Some growers use a screen with a V shaped profile (V scrog), some with a curved profile while others continue the horizontal screen up their GRoom walls (vertical scrog).
