LUI DAY 27 And Day 28

DAY 27

though the plants appear to be looking great overall they did show some minor transplant stress . . . the mushroom compost/FFOF mix actually seems to be a little bit rich in transition from the seedling mix . . . a couple of the babes showed the slightest bit of burn on their leaf tips . . . as these plants moved up in containers they also moved under a different light array . . . we’ve got about 300 watts of bright white fluorescent growlight at this stage . . . it’s something a growing friend passed us recently in trade . . . a 6 x 54 watt T-5 4 Foot fluorescent fixture . . . covering a 4′ x 2.5′ or 3′ footprint that’s something like 27-32 watts per square foot . . . a couple of the plants show a slight sign of heat stress on the leaves . . . it looks somewhat like a radiant heat/light burn . . . this isn’t logical since these plants are actually short and squat examples . . . they actually sit slightly below and further away from the light source than their siblings who show none of same “burn” symptoms . . . probably this is a reaction to the stress of re potting . . . the lights were raised far enough that heat should not have been an issue . . . and siblings next to them and higher than them in the canopy look perfect . . . so it’s probably nothing of concern . . . likely we’ll give a light folair feeding tomorrow to ensure continued vigor . . . as you can see from the attached Day 27 pic . . . we are being somewhat hyper-critical . . . the plants look great at a glance . . . once these babes get over any stress associated with transplant . . . this will be the the stage where we expect most strains to really “beef up” . . . the 5 quart containers support strong growth to more than a foot in height . . . and the strong white light will promote good vegetative growth and short inter node length . . .

LUI Day 28

. . . . due to a uncooperative camera battery and a limited schedule we don’t have an “in progress” shot for this day (which marks the end of their fourth week) . . . the battery is now fully charged . . . and soon we’ll be purchasing a back-up battery so this won’t happen again since the babes were a little stressed from transplant we did raise our light array for 24 hours . . . we only raised it a foot and lowered it again to a normal height as soon as a day had passed . . . the 6 x 54 watt T-5 fluoro array is by far the brightest fluorescent light we’ve ever seen . . . so we decided to give our freshly transplanted babes a lil break from the intense light . . . the lights were raised part way through day 27 and lowered on day 28 . . . our normal height for this light array is something in the range of 6″ to 10″ from plant canopy (depending on air circulation and room temp) . . . so we raised the whole array up to about 18″ for a day to give the babes a little break in intensity . . . we did water with plain tap water yesterday . . . since the soil mix was a rich organic base they should have plenty of available nutrients to support vigorous growth without any added nutrients for a watering or two . . . when we say “tap water” we suppose we’d better clarify . . . we’re talking water from the cold water tap that has been allowed to sit for a minimum of 24 hours . . . hot water heaters tend to concentrate mineral content . . . so water from the hot water tap is avoided . . . we work hard to build and maintain healthy populations of beneficial microbes in our soil . . . so using water with chlorine isn’t on our agenda . . . that’s part of why we suggest that water sits at least 24 hours before use . . . the chlorine gas which is dissolved in many water supplies will disappear within 24 hours if allowed to sit uncovered . . . the other reason is to allow the water to moderate to room temperature . . . during the winter season some tap water can come out cold enough to shock plants and their roots . . . some nutrients become unavailable at colder temps so we try to use water that’s near room temperature . . . we want to add that letting the water sit on a cold cement floor is only a little better than cold winter tap water in most cases . . . if your water is standing on cold cement we suggest sitting it instead on a cheap plastic mat or similar insulation.
