I have a growing facility that I use to harvest marijuana, growing pot is not too hard, if you guess what you are doing, however, I have experienced a lot of trials and a fair amount of errors, and one thing that is actually hard is week more than five in the growing stages, and there is the vegetative period and then the flowering stage.
The final week is key when getting a five star quality product.
Messing up in the final week is consistently such a heavy letdown. I spend weeks monitoring the lights around my products to make sure nothing gets burned or even slightly overheated. I also watch out for moisture as well as not get too dry or have a product covered head to toe in bugs. A different issue is that if I mess up the nutrients in week 6, the stink of the pot quickly swings. I need to cut back as well as allow the buds to produce their own natural stink. Other things I need to do in the final week of growing is monitor temperature as well as humidity. The temperature control with pot is quite tricky. This is why I have a little cheat sheet for it. I use ductless Heating as well as A/C for the first seven weeks. I have the control component set on a timed program to change from heating to cooling at evening. The final week I need a little less power. I use a space furnace to get the facility up and running, but not overheated. Then I use window A/C for the evening time cooling affect; When it comes to humidity, I rely on both a humidifier and dehumidifier. A lot of air quality swings in the growing facility depends on what is happening outside.
