Well, getting my head around the whole grow concept is still slightly difficult. I am really hoping that I am not missing anything. I do have number of questions and I would greatly appreciate it if you guys could answer them. Their quite long so please bear with me. My first question is regarding heat. My grow room replaces all the air in the room easily. This is good in the summer but in the winter it will be a cold room for around 8 months. I have a grow tent in this room. If the room is too cold will I not be able to use it or is there some ways I could make it acceptable? I was thinking about putting so heaters outside the grow tent that are hopefully cordless because I only have one outlet to use (ofc with a power bar in it but I don't want to overload). I also wondering if not using any coolers and letting the light heat be used towards my benefit in the cool room would be a good idea. Secondly, I was wondering about space. My tent is 4X4 feet. I initially thought that means that I could fit 16 plants because it is 16 square feet but I read in my cannabis grow bible that it could fit a maximum of 9 plants, is that accurate or could I fit more? Next, I have been reading about things like trimming, flimming, LST, and SCROG. This will be my first grow, I am thinking about deffinatly trying trimming or flimming but I was wondering would you guys recommend a SCROG for first time? For the smell would one carbon filter be enough for lets say 9 plants or should I also invest in maybe a DIY de-orderizing bucket? I have been reading many mixed things about lights. Including ballasts which I don't fully understand. Is there anywhere where I can get a full light kit so I don't need to buy extra things? I really appreciate all the help GC has given me!
