Light


Without light, the plants cannot grow. In the countries in which marijuana grows best, the sun is the source of light. The amount of light and the length of the growing season in these countries results in huge tree-like plants.
没了光,植物就不能生长。在那些大麻生长最好的国家,阳光是非常充足的,在这些国家里,生长季的充足的阳光可以让大麻长的和树一样。
In most parts of North America, however, the sun is not generally intense enough for long enough periods of time to produce the same size and quality of plants that grow with ease in Latin America and other tropical countries. The answer to the problem of lack of sun, especially in the winter months, shortness of the growing season, and other problems is to grow indoor under simulated conditions. The rule of thumb seems to be the more light, the better. In one experiment we know of, eight eight-foot VHO Gro-Lux fixtures were u
sed over eight plants.
在北美,阳光是不足以让植物长这么高的,拉美和其他的热带国家是可以的,问题就是生长季缺阳光,尤其是冬天,所以只能室内了。原则上就阳光越多越好,根据经验,8根八英尺(两米四)的高输出Gro-Lux可以供八株植物使用。
The plants grew at an astonishing rate. The lights had to be raised every day. There are many types of artificial light and all of them do different things to your plants. The common incandescent light bulb emits some of the frequencies of light the plant can use, but it also emits a high percentage of far red and infra-red light which cause the plant to concentrate its growth on the stem. This results in the plant stretching toward the light bulb until it becomes so tall and spindly that it just weakly topples over. There are several brands of bulb type.
植物涨的的非常快的,所以光的量要每天增加。有好多种人工光源可以用,每种对你的植物起的作用是不一样的。普通灯泡可以发出若干植物所需要的光波,但是灯泡也会发出很多远红外和红外线,这两种光线会导致植物的茎过度生长,结果就是你的植物会长的很高很高(不是什么好事)。有下面几个牌子的灯泡可以选择。
One is the incandescent plant spot light which emits higher amounts of red and blue light than the common light bulb. It is an improvement, but has it drawbacks. It is hot, for example and cannot be placed close to the plants. Consequently, the plant has to stretch upwards again and is in danger of becoming elongated and falling over. The red bands of light seem to encourage stem growth which is not desirable in growing marijuana. The idea is to encourage foliage growth for obvious reasons. Gro-Lux lights are probably the most common flourescent plant lights.
一种是植物灯泡(?),这个可以比普通灯泡放出大量的红光和蓝光,这是个改进,但是这算不算是个倒退呢?
它很热,不能放植物太近。结果是,植物只能越长离光越远,最后歪倒下了。红光似乎也可以让茎生长,这个对大麻来说是没什么好处的。我们的目的是要让叶子长的非常好,Gro-Lux 灯光可能是嘴普遍的植物灯了。
In our experience with them, they have proven themselves to be extremely effective. They range in size from one to eight feet in length so you can set up a growing room in a closet or a warehouse. There are two types of Gro-Lux lights: The standard and the wide spectrum. They can be used in conjunction with on another, but the wide spectrum lights are not sufficient on their own.
根据我们的经验 这个东西可能是最有效了。灯光长30公分到两米四,这样你就可以在柜子里或者在你的储藏间用。有两种Gro-Lux 光源,标准的和广谱的,两种可以一起协调使用看,但是广谱的Gro-Lux单独用的话效果就差一些了。
The wide spectrum lights were designed as a supplementary light source and are cheaper than the standard lights. Wide spectrum lights emit the same bands of light as the standard but the standard emit higher concentrations of red and blue bands that the plants need to grow. The wide spectrum lights also emit infra-red, the effect of which on stem growth we have already discussed. If you are planning to grow on a large scale, you might be interested to know that the regular flourescent lamps and fixtures, the type that are used in commercial lighting, work well when used along with standard Gro- Lux lights. These commercial lights are called cool whites, and are the cheapest of the flourescent lights we have mentioned. They emit as much blue light as the Gro-Lux standards and the blue light is what the plants use in foliage growth.
Now we come to the question of intensity. Both the standard and wide spectrum lamps come in three intensities: regular output, high output and very high output. You can grow a nice crop of plants under the regular output lamps and probably be quite satisfied with our results. The difference in using the HO or VHO lamps is the time it takes to grow a crop. Under a VHO lamp, the plants grow at a rate that is about three times the rate at which they grow under the standard lamps.
光谱灯本身就是按辅助光源设计的,价格也比标准的便宜一些
People have been known to get a plant that is four feet tall in two months under one of these lights. Under the VHO lights, one may have to raise the lights every day which means a growth rate of ate least two inches a day. The only drawback is the expense of the VHO lamps and fixtures.The VHO lamps and fixtures are almost twice the price of the standard. If you are interested in our opinion, they are well worth it. Now that you have your lights up, you might be curious about the amount of light to give you plants per day.
The maturation date of your plants is dependent on how much light they receive per day. The longer the dark period per day, the sooner the plant will bloom. Generally speaking, the less dark per day the better during the first six months of the plant's life. The older the plant is before it blooms and goes to seed, the better the grass will be. After the plant is allowed to bloom, its metabolic rate is slowed so that the plant's quality does not increase with the age at the same rate it did before it bloomed.
The idea, then, is to let the plant get as old as possible before allowing it to mature so that the potency will be a high as possible at the time of harvest. One relatively sure way to keep your plants from blooming until you are ready for them is to leave the lights on all the time. Occasionally a plant will go ahead and bloom anyway, but it is the exception rather than the rule. If your plants receive 12 hours of light per day they will probably mature in 2 to 2.5 months.
If they get 16 hours of light per day they will probably be blooming in 3.5 to 4 months. With 18 hours of light per day, they will flower in 4.5 to 5 months. Its a good idea to put your lights on a timer to ensure that the amount of light received each day remains constant. A 'vacation' timer, normally used to make it look like you are home while you are away, works nicely and can be found at most hardware or discount stores.
