I have grown in the past, but have very little experience. I am going to do a DWC grow in a 2x2.5ft grow tent. I have a 400w light and will turn it down to 50% so that I don't have to buy another light. If I am using 200w of light in a small space how much bud can I expect? I know this is a difficult question as it depends on many factors, but what is a reasonable range I can expect? 2-6 ounces? 4-10? I am worried the electricity cost may be more than going and buying from a dispensary.
