  1. Hi all, I'm new on the forum and the growing world so bare with me please I was trying to find a better section where to post this but I couldn't seem to find one, so here it is. (Moderators feel free to move around, or please PM me before removing as it'll be a quite long one ). So, a bit of background. I've been a smoker/lover for about 20 years, then for unknown reasons I started having bad reactions to (I think) THC so I had to quit Now, this all CBD world is exploding all around, did a bit of research about medical strains and, as where I leave it's impossible to find anything but crap, I decided to give it a go and try and grow my own. Problem is I don't really know if these weaker strains will cause me the same problems when "consumed" So I'd like to stay on the cheap and upgrade further on in case of success. I've ordered some Sweet Nurse Auto CBD 5-10% THC/10-15% CBD and CBD Critical Cure 5% THC/8.5% CBD (and I also received a whole bunch (10/12) of high THC seeds), started buying some of the needed equipment and I'm "building" my tent (80x90x150cm, I used electrical pipes for the structure and I'll cover it with cardboard using emergency blankets as reflective material on the inside). As for lights I went for LED and I got a cheap COB 300w one off ebay (not sure if linking is allowed https://goo.gl/ugPPM6 ) Now the questions: I've been reading about fans and filters but I've seen on youtube some pretty experienced growers having good results without and saying that for air circulation it's enough to open the tent once/twice a day (https://youtu.be/lt-KNNAY80g min 4.14) And adding 1/2 small conventional fans for airflow. What's your take on that? This leads to opening the tent, from my understanding it's ok to open the tent given you respect the light cycle (hence you open it when the light is on and keep it close, especially during flowering, when the light is off). Is that right? Ventilation when the tent in closed. I was thinking to add a line of small holes close to the bottom on one side (where I'd put my fan so that it would kinda pull fresh air in from there) and the same on the top to the opposite side (from where the warm air is supposed to get out). Would that do? Also, shall I worry about the light leaking in from those holes or, making them small enough (say 6 holes 10mm), the amount of light will be irrelevant? Finally, last but not least, I'd like to go as "organic" as possible, avoiding chemical nutes (even because they require flushing and water is kind of an issue on the island where I leave). I do make my own compost (coffee ground, tea leaves, egg shells and all the veg waste from salad, greens, fruit etc...), would you use it when potting? What else you suggest to use as an aid? I think that's about it for the moment, be assured I'll be back bothering you guys with more questions once I'll start! I can't wait!!! I'll probably start with one because of the very small tent, most probably I'll go with the Sweet Nurse which is stated to be ready in 8 weeks from germination! Peace
