I have been researching alot about the contruction of grow room lately and have watched cervantes movie. I have a few simple questions that some of you will probably be able to answer pretty quickly. 1. When he constructs the 8x8 grow room, does he make a roof and line that with the reflective white material also? I didn't notice if he did and i dont think they mentioned it. I assume a roof was created otherwise the odour would be able to roam freely throughout the house. 2. When he built the growroom there didnt seem to be any way of getting in or out as the whole thing was lined with the reflective plastic. Was there a door or hole to get in and out of? 3. When he is making clones, he says that you take them from a mothered vegatative plant - meaning that you already know its female. I thought that you sex the plants at the end of vegetation heading into flowering? Or is the only way to tell if the plants came from a previous female clone? 4. Can you keep clones for a long period of time, or do you have to plant them when they are ready? Also about the mother plant, do you keep it in vegetative state until it dies? Do you maintain the 18/6 light schedule during its entire duration? Do you keep your mother plant with your other vegetating plants, or do you keep it seperate? These questions may sound simple but they have been bugging me for a while and i wanted to know what the deal was. Thanks guys.
