As to allow these two short bushy plants a chance to stretch a bit, the lights have been moved up a few inches. For one, to allow the buckets to remain cooler and two, to see if I can get a few inches out of these "shorties". Just having moved the lights a few inches and giving tin hat covers to the buckets has brought the water temp down to 76. Don't forget I also moved the fan to blow right on the buckets. My belief is though due to moving the lights just that small amount allows the exhaust above to pull the heat a bit better and the bulbs are not warming the tops of the buckets. All in all though, the last 14 hours has led to a major "veggie" growth to this plant. The middle looks like a head of cabbage and the leaves have extended past the edges of the open part of the net pots. Yes I have been measuring these babies in mm increments, can't help myself.
