What you should understand is that choosing a variety is very essential when it comes to 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.
There has been an increase in the popularity of growing cannabis indoors. If this is done properly, then such would certainly produce a fantastic quality that is usually better than those 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. Such lights would take hundreds of Watts of electrical power in order to run and are often HPS but fluorescent lights, LED light, metal halide and also other types have all been used successfully.
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 keep in mind that the successful indoor grower should use high light to ensure that the plants get to close to the light maximizing the intensity to be able to reach the leaves as well as buds of the plants. For such personal recreational or medical grower, then such growing area of one to two square meters may have 600W or 400W HPS lamp.
Indoor cannabis grower should be careful that the plant won’t grow really near to the hot light and damage itself. 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. Those cannabis plants may be bent over and tied when they get too tall. Some of the indoor growers would train their plants in this manner to get as much of the plant as possible close to such high intensity light.
Certain strains would respond quite well by pinching out such growing tip of the plant after the 4th or the 5th leaf pair. This would result to plants which are smaller and bushy with no dominant main growth stem and they are preferred for those smaller growrooms.
