Growing Tricks

There are a lot of things that you will have to do especially if you are growing the marijuana plants inside. Every single trick that you can learn is going to help out a lot and it will add up a lot for the best results possible to deliver you good dope.

Maturity

You could get the plants to reach maturity level within 5 weeks if you want to rush things. All you have to do is keep the amount of time that the lights are on the plant to only fourteen hours a day. The main problem with this is that the yield will not be as large. Ideally you will slowly drop down the amount of time that the plants have light until it reaches fourteen hours per day.

Water

You could stop watering the marijuana plants once the resin starts to reach the flower level. If you do this then the marijuana plant will produce more resin then it would if you kept watering them.

Cutting off a Flower

If you cut off the flower at the point where it connects with the marijuana plant a new one will grow back in a few weeks so your yield will be slightly bigger.

Ethrel

Spraying the marijuana plants with Ethrel when they first start growing can help yield more female weed plants then usual and the flowering process will probably speed up as well.

As you can see from just this short list there are a lot of little things that you can do to assist the growth of your marijuana plants for the better. Utilize these tricks so you can grow the best ganja possible.
