HomeGrown Season 7!
Getting pretty frosty for #TrichedOutTuesday around here! These Cap Junkies are at day 63 and this room is smelling DANK!
I love where the senescence is at this point. I cut the nitrogen several days ago. They're still being fed an EC of 1.0 of PK, calcium sulfate and magnesium sulfate, but I'm about to cut the feed of everything except a few micros and calcium, served up in a bacterial tea.
Mostly I'll just let them eat what the microbes are still serving up in this Tilth Soil Bloom and ultimately the plants' own reserves of any mobile nutrients. I'll see nitrogen, phosphorus and magnesium translocate. Maybe a little potassium.
Anthocyanin is starting to pop.
I'll be drumming up a little abiotic stress as well, mostly a little drought stress, coupled with tanking temperatures and high VPD. Cool and dry with less water.
In another 10 days or so, the results will be an explosion of colors and fan leaves that are crispy. They will be even frostier than they are now, if you can believe it.
The trade is in the fade.
I got a chance to put this side lighting CUBE from Proximity to the test. I played with it last round, but I wasn't comparing apples to apples, as half the crop was in big soil and half in small coco.
For this round, I do have two different CABA bar lights that I've been beta testing. So the light quality is a bit different, but the wattage and PPFD are the same. And each plant is on the same diet of King Solomon nutrients, each in about 4 gallons of Tilth Soil.
I may eventually trial under canopy lighting, but side lighting made more sense to me. It doesn't get in the way. It doesn't get wet or dirty. But mostly the light is more evenly distributed closer to where the photosynthesis is happening. And the light is being delivered from the side, not from below, so many more of those photons are hitting the tops of the leaves and bud sites, where the plant expects them.
It's only 200W, instead of 400W.
One disadvantage I've found so far are a few direct contact burns where a leaf or a bud came in direct contact with a diode. But it really is minimal as I was able to train and trellis most of the stalks away from the light a bit.
It also felt a bit more obstructive when I reach into the canopy to defoliate, but that was also not significant. It's very similar in material and spacing to the PVC that I normally use for trellising. The bars are just a bit thicker to accommodate the lights.
I will publish final dry weights of this pattern against the control, but I can already tell it's going to be a bigger yield. This pattern has been consistently drinking about 12% more than the control, both with no runoff.
It's a total jungle in there, so it's a bit hard to see. But most of the lowers are visibly bigger. And there are more of them, as I didn't lollipop this pattern quite as aggressively. There is no larf on these plants. Everything has bag appeal. B buds at least.
Thoughts on UCL v. side lighting?
