From Melbourne, Australia.
Just coming to the end of our summer so planning an indoor tent grow, 31 cents per KwH power prices and space constraints are my main concern.
Q: When dimmed, do LED's retain their colour spectrum? - I'm coming from HPS and thinking of buying a dimmable LED so I can dictate the power consumption depending on my needs; which could be fluid.
Q: As my outdoor plants canopies seem to have a diameter twice that of the pots diameter, should I have an indoor plant pot half the diameter of available per plant grow space?
For the first question, yes, they do; It'll look the same, just less intense.
As for the second question, I think there are a lot of variables at play here like how long you'll be growing it, whether you're hydro or soil, etc. I don't think it'd be too hard to fill out a small tent with a single plant in hydro. The pepper experts can probably answer this better than I can though.
