I currently have a grow facility that I use to harvest marijuana, growing pot is not too hard, if you think what you are doing! I have experienced a lot of trials and errors! The main thing that is entirely hard is week many in the growing stages! There is the vegetative ordeal and then the flowering stage.
The final week is key when getting a high quality product, messing up in the final week is consistently such a big letdown.
I spend such a long time just monitoring the lights around our products to make sure nothing gets burned or even slightly warm. I also watch out for moisture and not get too dry or have a product covered in bugs. One of the other problems is that if I mess up the nutrients in week 6, the smell of the pot quickly changes. I am hoping to cut back and allow the buds to produce their own natural smell. A few 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 the reason why I have a little cheat sheet for it. I use ductless Heating and A/C for the first 5 weeks. I have the control unit set on a timed program to switch quickly from heating to cooling at night. The final week I need a little less power. I use a space furnace to get the facility warm, but not warm. After this I use window A/C for the night time cooling effect; 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 weather coming from outside.
