In a screen of green method the idea is the same as see of green except you use a screen to manipulate the plants into place by poking the buds through the screen and keeping the leafs under it. You do need to have air moving at all times under the screen it will keep out any mold or other problems. The idea is still the same with a screen you can grow closer then you can without. All the light is top light and you use a lot of it as well as top air circulation. Co2 will make it grow even faster. You grow from clones and only need to veg them for 21-30 dayâ??s. This method does require a mother btw and you need to think a little different then most but itâ??s fast and can grow quit a lot of pot in a very short time.
