* 07/28/2012: Jiffypellets set-up (18 in total) with lettuce seeds. Timer installed (2x yellow daytime outlets, 2x blue nighttime outlets, 4x white continuous power outlets). Day powers lights from 0600 to 2200. Night powers lift pump from 2200 to 2202 and again from 2300 to 2302. | * 07/28/2012: Jiffypellets set-up (18 in total) with lettuce seeds.

Amazon Sword very hardy, takes a lot of punishment. Power a problem as other events often borrow the extension cord; more permanent set-up needed. | ||
* 08/14/2012: Systems check. Amazon Sword is very healthy and deep green. Timer was incorrectly programmed; changed to use "night" outlets (blue) from 04:02 to 20:00, then again at 20:02 until 04:00 next morning (perpetual day). Lift pump triggers twice per day on the "day" (yellow) outlets from 04:00 to 04:02 and again at 20:00 to 20:02. Unfortunately this timer system does not have an option for "both off" at a given time. The seedlings are approx 2 inches tall; success rate for 18 pellets is roughly 75%; need to do a better sowing job next time around. Moved three pellets to edges of first tray; moved three to edges of second tray. Believe their "drooped over" state is due to lack of available light as previous programming set-up would have only accounted for four minutes total of "daylight". Ambient light from outside is minimal at best. Next check planned for 08/18/2012 (four days). Will re-assess plant performance at that time. Also added 1/3 cap (60ml) Miracle Gro as fish are not yet installed and plants have been without nutrients since 05/26/2012. Power still an issue and discussion is planned on return of The Area's directors around August 20th. | |||

* 08/25/2012: Systems check. Plants responding very well to change in lighting and re-positioning of pods. Root systems pronounced in four of the 18 initial pods; 50% of the remaining pods could possibly be salvaged as they have developed small seedlings but will need extra care/attention to flourish. Other 50% are potentially write-offs (no observable growth). Discussion remains to be had regarding stable power supply. Fish not yet added to system; pending confirmation of stable power source. | |||
