Week 3 Lowered LED grow lights to 18 inches. PPF/PAR meter reading 350 -400 umoles. Giving me a DLI (Daily Light Integral) range of 25.20 - 28.80 moles. Recommended LED PPF/PAR Values / DLI Based on 20 hrs of light. Seedlings 150 - 200 umoles / DLI 10.80 - 14.4 moles per day Veg up to 9" 450 umoles / DLI 32.40 moles per day Early bloom 500 umoles / DLI 36.00 moles per day Mid bloom 650 umoles / DLI 46.80 moles per day Late bloom 750 umoles / DLI 54.00 moles per day Ripen 400 umoles / DLI 28.80 moles per day *** Use extreme caution when going 700 umoles or higher this could cause leaf burn*** PPF measures the total amount of PAR emitted from the lighting system per second. PAR is the amount of light in the 400 - 700 nm color spectrum that can actually be used by the plant. PAR does not measure the amount of UV and Infrared that plays a part in trichome formation and cell quality. DLI is the total amount of PAR the plant has received per day Our goal is to have a minimum DLI in the 38-40 mole range when it bloom. https://www.waveformlighting.com/horticulture/daily-light-integral-dli-calculator https://www.lumigrow.com/application/cannabis/ https://horticulturelightinggroup.com/blogs/news/horticulture-metrics-par-ppf-ppfd-dli Using a infrared thermometer average leaf temperature was about 72 F with an average of 60% humidity giving me a LVPD (Leaf Vapor Pressure Deficit) of 0.58 kPa. Having your plants in the optimum LVPD ranges helps them absorb Co2 properly to conduct photosynthesis and allow the root system to adequately utilize water and nutrients. Using average leaf temperature is the best way to calculate LVDP. LED lights tend to have leaf temperatures lower than atmospheric temperatures in the grow room. Growers using HID, Fluorescent bulbs typically will have temperatures higher than room temperature. With HPS leaf temperature can be 8 - 10 F higher than room temperatures due to the amount of infrared emitted by the bulb. Recommended LVPD Seedlings/Early Veg 0.4 - 0.8 kPa Late Veg/Early Bloom 0.8 - 1.2 kPa Mid/Late Bloom 1.2 - 1.6 kPa *** Danger Zone*** Below 0.4 kPa / Over 1.6 kPa https://www.dimluxlighting.com/knowledge/vapor-pressure-deficit-vpd-calculator/ https://www.blackdogled.com/lst Plants leaves are fairly dark green they received 0.25 liter light nutrient solution twice about 3 days apart. Started LST by laying down main stem and pinning smaller branches with 3.5 mm anodized aluminum bonsai wire bent into a hook shape on one end. Plants recovered from being manipulated a few hours later. Started to show a touch of stretching by the middle of the week along with some preflower pistils already starting to show by day 21. Saw the first signs of some nice fuzzy white roots growing out the bottom by the end of the week.
