HPS vs. Induction + CFL flowering comparison
Less than a week until harvest!
I decided not to modify the shade. Although I believe Bubba's advice would result in better yield, I felt it would not yield useful information to modify the cabinet in the middle of the grow. If this lamp is used in a future experiment, I will certainly make design changes based on his input.
The HPS clearly has more substantial flowers, and apparently more resin. I have used slightly larger pictures than before to try to show this off.

HPS vs. Induction + CFL flowering comparison
I am very interested in this grow. I have been in contact with a Chinese supplier. I was quoted almost $ 300 for shipping a 400 watt lamp 2700k with the housing (36 kg monster lol) ! So I asked for a quote on just the ballast and the lamp w/o the housing. The shipping comes to $ 80.00. I have negotiated a reasonable price but am still pessimistic with the credibility of its performance. This grow could determine my decision to buy one so please keep us updated
Thank you :jointsmile:

HPS vs. Induction + CFL flowering comparison
The final results are in!
Heights:
- HPS: grew about 14" above the soil. There was 22" of clearance to the lamp
- Ind: grew about 12" above the soil. There was 25" of clearance to the lamp
These clones can easily grow to 24"+ in this amount of time, so next experiment I will lower the lamps 8"-12" (depending on power used) to increase performance.
Yields:
The container used to weigh is 32 grams. All weights were done with freshly cut WET flowers:
- HPS: 195.9 - 32 = 163.9g
- Ind: 109.9 - 32 = 77.9g

Hey Van, I've been lurking here watching all the action...very interesting btw! Would you also post up the dry numbers when available? So what did you conclude? If the dry weights are comparable, looks like I'll keep running my HID's for awhile longer! Thanks a lot for taking the time do this and to post all this...I look forward to watching your next test, whatever it may be! :thumbsup:
