Its been 6 months since i have visited this webpage. Its good to be back. Got some more spare time now-a-days so I figured I would share my latest adventure with Recirculating DWC and my first try with vertical lighting. Strain is Grapefruit, she is a beauty and one I will be working with for awhile.
Since i started using this system over a year ago, I have moved from 18 plants to 12 plants down to 6 plants and kept the same size room or even larger. Yet, I have continued to yield the same and the bud is of an even higher quality. Vertical Lighting is the way!!! The vertical lighting gave me absolutely donkey ball buds from the very bottom of the plant, touching the floor, to the very top cola. The average bud size on each plant is about the size of my fist. I am NOT using CO2 this grow. I have found that while CO2 can really help pack on the weight and density, it really creates a lot of problems and since I am not trying to get a weight record here, I dont mind having my life easier. I still ran a sealed room (well i left the door open sometimes) and as you can see...there was no problem with lack of ventilation or fresh air.
Temperatures are between 70F and 78F in the daytime, controlled by an IGS220 controller and a 10k BTU A/C, and I drop it all the way down to 55F at night to help bring out the purple in the strain. I ran a total of 1 vertical 600 watt digital HPS, 1 vertical 750 watt digital HPS, 1 air-cooled 750 watt HPS over everything (kinda like an overall sun), and 4 T5HO bulbs. I decided to conduct an experiement between plants grown with just HPS and plants grown with HPS and with T5s overhead. While the T5s did not yield quite as much, the bud was even more full of THC and the buds themselves were gigantic. The top cola is thicker then my forearm. 3 oscillating fans and each vertical light has a squirrel cage cooling it from below.
Let me know if you have questions. Plants are about 4 days from being picked, on their 4th day of flushing. 8 weeks old. I am expecting over 3 lbs from the room.
Here are some pics from the beginning to the end.
