Canny's Return

LIGHT: In acknowledgement of the fact that each of the positions in the garden gets a differnent amount of light, and to try to equalize the Total Light Integral of the grow, I began "shuffling" the plants daily, according to a formula, so that all plants get equal time in each of the positions. ENVIRONMENTAL MONITORING: I have been charting temp/humidity pretty regularly. But this week I received the and installed PulseGrow monitor to keep track of conditions within the tent to a higher level of detail. HEATER: One of the things I learn is: it's getting really cold at "lights-off" in the garden and, worried it may be slowing growth, I install a very small (100W) space heater in the garden that goes on low during the night period. This raises the temperature about 5 degrees, from around 64-65F to 69-70F. NUTRIENTS: began using weak nutrient solutions. I got sloppy with PH in here and made some assumptions that were not tested (underestimating the extent to which my PH would decrease as a result of the nutrients, and failing to test them...
