I read every word of your thread and I feel I have learned a lot from what you have posted. I am a beginner, much like you. I am an older gentleman that is tired of giving my money to the teenager "down the street", so I decided to grow my own crop. I have taken a lot of what was said in here and will be applying it to my box build. I have even purchased goods that was linked in this thread.
With all of that said, I am still a little unsure about your lighting. It looks like youre using only the T12 Florescent bulbs and it is working great for you. I have extended myself on my budget and I cant afford to get the CFLs for my first grow. I might be able to install them in the process, but for now I am not planning on them. Could you go into more detail of the types of bulbs you are using. Right now I have 40w, Cool White bulbs that produce 3200 Lumen. I thought only one light rail (containing 2 bulbs) would be enough, but I see I will need to purchase a few more. Any info on this would be helpful.
I also have some questions about your soil and nutes, but I will ask those questions when the time comes. I am still waiting for a lot of my supplies to arrive, including the seeds. Youre doing a great job, Sativus and youre an inspiration to me, so thanks for posting all the fine details you have and I hope you keep doing so.
