This week consists of July 2, 2022 thru July 8, 2022 - Seeds were planted on May 27th, 2022 and they all sprouted on May 31st, 2022 (~4 days) Beginning of flower so I changed the light to use the HPS bulb. Maintaining temp and humidity during flower with lower temperatures and a higher VPD has been a bit challenging because of the outside temperature but it went ok. I will start to lower the AC unit temperature during dark period to get a larger difference but it makes it hard to keep the CO2 levels high with the AC unit on more often. The plants are using up a lot more water now so I have increased the feeding/water frequency to at least every other day. LIGHTS: I'm running the lights on an 18-6 schedule. I have the dark time scheduled from 11am to 5pm since the lights increase temperature and during that time the outside temperature is at its highest so it seems to be easier to maintain proper temperature ranges with the light off during that period. Swapped out the metal halide bulb to the high pressure sodium on July 6th since the plants have been in flower. WATER: July 3rd: ~750 - 1000 ml of 6.1 PH and 880 PPM. 15 ml/gal of Big Bloom 10 ml/gal of Grow Big 5 ml/gal of Tiger Bloom 5 ml/gal of Cal-Mag July 6th: ~1000 ml of 6.1 PH and 1120 PPM. 20 ml/gal of Big Bloom 15 ml/gal of Grow Big 10 ml/gal of Tiger Bloom 5 ml/gal of Cal-Mag July 7th: ~1000 ml of 6.1 PH - oxygenated water TEMP/HUMIDITY: A max of 84.8F and a min of 71.4F with an average of 79.7. VPD was pretty consistently in a tighter range with the average being around 1.41. Whole week numbers> Temp - 79.7F avg - 71.4F min - 84.8F max Humidity - 59.4% avg - 32.0% min - 81% max VPD - 1.41 avg - 0.53 min - 2.55 max CO2: Floating ball is between .5 and 1. This lets a more gradual amount of CO2 to enter the tent and I now get a more stable level of CO2 that fluctuates between around 1000 ppm and 1300 ppm. The regulator is still plugged into the same outlet as the lights so it turns off on the same light/dark schedule. PAR: PPFD between 300-1100. I got a legitimate par meter and now have a much better idea of how much light is being received on each plant. The tops of some plants are getting the 700-1100 range and some side leaves are getting in the 400-500 range. The new bulb gives off a lot of light and the plants have grown much closer to the bulb so some tips are getting a high PAR so they should make excellent use of the increased CO2. ISSUES: The plants are getting a lot bigger and taking more water per week. I removed some of the plants and moved them into a different tent to allow for enough room for them all to bush out and finish stretching. TECHNIQUES: I implemented a very small amount of LST throughout the week and removed only a few inner leaves(defoliation) to increase the light to some of the inner branches.
