You need to know that selecting a variety is really important in growing marijuana. The quantity and yields of the plants which are grown under those artificial lights would have to depend on the variety of the seed or if the plants are grown from the clones or seeds. Also, you will have to consider the number of days of growing those plants are placed into flowering as well as the optimization of such climatic conditions of such grow-room.
Surely, there has been an increase in the growing of cannabis indoors. If done right, such would produce fantastic quality that is often a lot better than being sold on the streets. You should also know that growing cannabis indoors really depend on using the powerful artificial lights to be able to replicate the effect of the sun. These lights actually take hundreds of Watts of electricity to work and they are often HPS lights however the other types of lights are quite fantastic when growing those marijuana buds.
The cannabis actually loves light and the successful indoor grower would try to deliver as much light as it can. Consider 250 watts/m2 as the minimum starting point and then aim for two to three times that level if you can. If there is more light, then you will find denser and bigger buds and you can also get to enjoy bigger yields as well. You have to remember that delivering high light could level the successful indoor grower to keep the plants near the light and maximize the light intensity and reach the leaves and the buds. Usually, the personal recreational or medical grower will have such growing area of one to two square meters below one 400W or 600W HPS lamp.
The indoor cannabis grower should also make sure that the plant doesn’t grow really near the hot light to avoid causing damage. When the light would feel cool to the back of the hand, this will be cool for the plants as well. For such 400W lamp, growers may not want the plants to grow 40 to 50 cm of the bulb. Such cannabis plants can also be bent over and tied if they become too tall. Some indoor growers would also train the plants in this way to get much of the plant near the high intensity light.
Particular strains would respond really well through pinching out the growing tip of the plant after that fourth or fifth leaf pair. Such results to the plants that are smaller and also bushy without dominant main growth stem and they are also preferred than the smaller growrooms.
