I have a grow facility that I use to harvest marijuana.
Growing pot is not too hard, if you know what you are doing.
I have experienced a lot of trials and errors. One thing that is really difficult is week six in the growing stages. There is the vegetative stage and then the flowering stage. The final week is key when getting a good quality product. Messing up in the final week is always such a huge 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 and not get too dry or have a product covered in bugs. Another issue is that if I mess up the nutrients in week 6, the smell of the pot significantly changes. I need to cut back and allow the buds to produce their own natural smell. Other things I need to do in the final week of growing is monitor temperature and humidity. The temperature control with pot is quite difficult. This is why I have a little cheat sheet for it. I use ductless HVAC for the first five weeks. I have the thermostat set on a timed program to change from heating to cooling at night. The final week I need a little less power. I use a space heater to get the facility warm, but not overheated. Then I use window AC for the night time cooling affect. When it comes to humidity, I rely on both a humidifier and dehumidifier. A lot of air quality changes in the growing facility depends on the outside weather.
