Indoor: 1989.5 Daletas ’17 dmg: Plant With 500 Watts of Heat

With the early start cold temperatures were expected. However, it seems this year is especially cold so the watts of heat has been increased to 500 watts (up from 200watts). With a blanket and tarp over the cold frame and the heaters running, the temperature was kept warm 60-70F (15-21C). Also, since it is still early in the season light is being supplemented to replicate a May/June photoperiod to help further encourage growth. However, the heaters alone do not add any light to provide control over the photoperiod and temperature independently.

At this time, the indirect heater is not being used because this plant is still inside the small structure. Due to the smaller sized are it is more efficient to just heat this smaller volume. However, with the data collected and equipment in place it will be a simple “flip of a switch” to use the larger indirect heater. Once the plant outgrows its current structure the electric heat will be replaced with the indirect heater which requires diesel fuel. The goal is for the plant not to have any noticeable changes in environmental conditions despite the change in heat source.

The plant is on the ground and running so the goal is to keep a good thing going which is the reason for the supplemental light and heat (not to mention CO2 enrichment).
