Indoor 1989.5 dmg Daletas ’17 (F: 1756 Howell/Jolivette x M: 1625 Gantner)
“Best” Treatment
While this plant will be grown indoors for the season, there have been some extra additions to the early season cold-frame to provide improved growing conditions from the start.
Heat
100 watt reptile heat lamp is standard in my cold-frames so this is nothing new. However, due to the consistently cold nights there may be two per cold frame to increase the heat around each plant.
Light
There is a 315watt CMH (Ceramic Metal Halide) DimLux grow light that is dimmable and running at 280 watts. This is on a timer and comes on at 3:00am and turns off at 10:00am to lengthen the day (photoperiod) and provide some additional heat during the coldest portion of the day. While the bulb that comes with this unit is quite good, I elected to upgrade even further to a Philips Green Power Master Color CDM bulb, 315 watts 3,100K.
Carbon dioxide
In addition there is also a 20 pound CO2 tank and controller with Fuzzy Logic. The sensor is mounted on a PVC pipe that is at about plant height to allow for a representative reading. This unit comes on from 4:00am (an hour after the light comes one) until 6:00pm (about an hour and a half before sunset) at a rate of 900ppm with a flow rate of 2 cubic feet per hour.
