Need some help to determine in what I have to work with is okay. Am a newbie, so bear with me. Need to grow for personal use for back problems and buying is just getting to be way too much. Here's what I got: - Am going to use an old walk-in shower that is about 3ft x 3ft. Am only going to have 3-4 plants at a time and will most likely veg indoors and flower outdoors as weather is good all year round (I hope I said that right). - I have (8) 14.5w 5000k 1575 lumen led (100w equivalent) bulbs I already had. I am in the process of making a light that would use all 8 bulbs (4x2) with reflectors. 1. Will this work? Is this enough light? 2. Would this be okay to mix an autoflower or two in? 3. Is there any way to rough guess-timate how much I could get with this? I know most of y'all here are probably experts, but hopefully you can have a little pity on a novice and try to help me out.
