2024-12-25 to 2024-12-31
With less than 2 weeks remaining to this grow, I started the flush - straight water w/ CALMAG for one more watering, then straight water for the last 10 days. With the high humidity from all the rain we have had, as well as higher than average winter temps, it has been difficult to find that sweet spot for Vapor Pressure Deficit (VPD). However, we are predicted to have cold and dry weather starting New Years Eve and lasting for a couple of weeks. This will allow me to control the lung room environmental aspects to try to hit that VPD sweet spot for the last couple of weeks of flower.
12-26 Day 47/101
Flushed w/ water and CALMAG - 1.5 gal each
12-30 Day 51/105
Trichomes are mostly milky, with less than 5% amber
12-31 Day 52/106
.5 gal water + CALMAG each. Leaves are starting to show nutrient deficiency from the flush. Water overflow in trays is reddish in color, indicating a large amount of nutrients still in the soil.
@popcornsutton,
Sorry for the late reply. These lamps will max out at around 60k LUX at 100%. I'm actually running two of the SF4000 lights in one of the 5x5 tents. I have also looked at changing my lighting to the Spider Farmer G or SE series bar-style lights. It seems they are more popular among many of the successful growers I follow on social media. The SF4000 lights would be perfect for a 4x4, but not quite good enough (in my opinion) for the 5x5 tents. They will have to do for now, since the upgrade for both tents would be around fifteen hundred.
Great grow!
Cover top soil with cutten grass, wood chips, any thing organic to increasy root, maximize the potencial of your soil !!
Anyhting that make the top moist, and slow release anything or make a home for the microorganisms....
@Psilocubensis,
You would do this with Coco Coir? I try not to add anything that might bring in disease or pests from outside. I also use cloth pots to keep the soil well drained. Coco Coir should be treated as Hydroponic in the sense that you are maintaining the nutrient balance and PPM ratios, testing the excess water/feed that flows through the cloth pots, into the tray.
