I took amp;amp; uploaded a pic on 15 Oct 2016, this pic was taken 20 Oct 2016. The plant has show dramatic increase in growth in just 5 days. I am a bit concerned with the density of the pepper plant, more dense than normal. Am waiting to see peppers forming on the plant, there are flower buds and some flowers look like they have set fruit. Peppers are self pollinating. The light fixture has 4 tubes two red and two blue, am wondering if I should add a white LED tube, maybe replacing a red or blue tube.
