GGAF tent 1st grow ever

This week consists of June 3, 2022 to June 10, 2022 - Seeds were planted on May 27th, 2022 and they all sprouted on May 31st, 2022 (~4 days) After getting off to a great start with germination where all 10 seeds were successful the first week of vegetation didn't go quite as smoothly. 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. WATER: June 4th I tested the soil PH and it was reading low at around 5.4 in all the tested pots, varying slightly higher and lower for each one. Thinking that I would have to raise the PH of the soil I then added the recommended amount of Big Bloom to distilled water that then tested at 7.7 PH I watered 3 times with about 50ml per watering. Then after doing some more research I decided to just use 6.3 PH for watering and continued to add 50ml of water 2-3 times a day. June 6th I then scaled back to once a day around 50 ml of 6.3 PH water. Starting on June 7th I lowered the water PH to 6.1 and stopped watering every day on June 8th and waited until the soil looked and weighted dry and then watered all plants with ~480ml of 6.1 PH and 400 PPM. This had approximately 1tsp/gal of Big Bloom but I kept adding more distilled water until I got the PPM down to 400 and then a touch of PH up/down to get the water right around 6.1. Water was at room temperature. TEMP/HUMIDITY: I started out the week trying to maintain a max light temperature of 80F and then a dark temperature around 74-76F. This was difficult as the outside temperatures started to climb into the mid to high 80s. On June 7th after getting great advice from @LegacyMarketFarm I pivoted to trying to maintain a smaller range between light and dark and increasing the max light temp a few degrees to a max of 84F and a min of 78F. Now humidity became a real challenge the last few days since the outside temperature went into the high 80s. The small 1 gallon humidifier that was set to run on a sensor with a max 75% was working well at lower temperatures but just couldn't cut it when the AC unit has to run more often due to the high outside temp. VPD was stuck above 2 for a while. Luckily I had another humidifier and added that to the other side of the tent just running all the time and turned on the humidity sensor for the fan controller and would trigger when it raised above 80%. This allowed the tent to return to good VPD much quicker after the AC unit would run and allowed for an average VPD in the desired range. The last day of the week I was able to get the variables ironed out a bit and am now seeing much more stable numbers in the desired ranges (except for the brief period when the AC runs and it dries out the air but the humidifiers quickly bring it back up): Temp - 79.4F avg - 76.0F min - 82.7 max Humidity - 69.3% avg - 40% min - 93.0% max VPD - 1.05 avg - 0.23 min - 2.06 max with the distribution being majorly in the 0.7 to 1.4 range and the high and low ends usually only occurring for a few minutes at most. Whole week numbers> Temp - 77.7F avg - 67.7F min - 92F max Humidity - 57.8% avg - 31.0% min - 93% max VPD - 1.37 avg - 0.20 min - 3.28 max CO2: Starting on June 5th I introduced carbon dioxide into the tent during the light schedule. The sensor is set to 1200 ppm and takes a minute to run on or off after the trigger level is set. This has the in tent ppm fluctuating between around 800 ppm and 1400 ppm. The regulator is plugged into the same outlet as the lights so it turns off on the same light/dark schedule. PAR: I only have a phone app light meter but so far the PAR appears to be sufficient for the increased CO2, at least in the area directly below the light with a PPFD between 400-600. Some of the plants that are on the edges aren't growing as fast as the others likely due to the reduced PAR. I did receive one of the ViparSpectra KS5000's that I ordered for a new tent but maybe I'll try it out in this one first before setting up the new tent to make sure that the plants can fully utilize the increased CO2 levels. ISSUES: Looks like one of the plants might have gotten nutrient burn and had some light spots on the leaves, I didn't do anything other than to just use some distilled water for watering for a day and then just made sure my watering solution was properly balanced afterwards. The spots haven't fully gone away but it continues to grow and seems relatively healthy otherwise. TECHNIQUES: I plan on implementing LST and ScrOG in the coming weeks. I decided against FIMing for now. I don't have experience caring for stressed plants and it's enough work just dealing with the challenging temp/humidity issues from my current tent location.

This week consists of June 11, 2022 thru June 17, 2022 - Seeds were planted on May 27th, 2022 and they all sprouted on May 31st, 2022 (~4 days) Pretty good week with only a pest issue, it was a good week for temperature and humidity, nutrients, watering, and CO2. 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. It was cooler this week with fewer temperature extremes so maintaining a proper temp and VPD was less challenging. WATER: June 14: ~480ml of 6.1 PH and 400 PPM. 1 tsp/gal of Big Bloom 1 tsp/gal of Grow Big 0.25 tsp/gal NPK RAW B-vitamin 5 ml/gal GreenPlanet Root Builder Water was at room temperature. TEMP/HUMIDITY: A max of 84F and a min of 76F with an average of 80.2. VPD was pretty consistently in a tighter range with the average being around 1.1. Whole week numbers> Temp - 80.2F avg - 75.9F min - 85.7F max Humidity - 66.7% avg - 33.0% min - 93% max VPD - 1.17 avg - 0.23 min - 2.53 max CO2: Had a mishap with the regulator on the tank and most all of the CO2 leaked out so I had to refill the tank. After that I tweaked the settings on the regulator and now it is releasing CO2 at a rate 20% of what it was before, floating ball is at 2 now instead of near 10. 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 400-600. ISSUES: Starting a few days into last week I did notice some nats in the soil. I didn't take it seriously at first but then a few days later looked into them and how they show up and then made adjustments to get rid of them. I stopped watering for about 5.5 days to fully dry out the top of the soil. I then added a bunch of yellow sticky paper around the pots and sprinkled diatomaceous earth around the top edges of the soil and mixed it in a bit in the top of the soil. This seems to have worked very well and they are all but gone and will likely be fully removed in the next couple days. Next time I plan on adding diatomaceous earth to the soil as an amendment in the ratio of 15 grams per gallon of soil. TECHNIQUES: I implemented LST on the final day of the week. Ideally I would have done some of them earlier but I just didn't have the time this week.

This week consists of June 18, 2022 thru June 24, 2022 - Seeds were planted on May 27th, 2022 and they all sprouted on May 31st, 2022 (~4 days) Pretty good week with lots of LST, it started to get into high 80s and low 90s this week but was able to maintain decent temperature and humidity ranges with some ac unit and tent vent adjustments. 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. It was hotter this week with more temperature extremes so maintaining a proper temp and VPD required some adjustments. I'm considering going to a 24 hour light schedule for a few days; using a soil meter the moisture on all the pots is still rather moist over 3 inches down. WATER: June 18: ~750ml of 6.1 PH and 650 PPM. 15 ml/gal of Big Bloom 10 ml/gal of Grow Big 2.5 ml/gal of GreenPlanet MediOne 2.5 ml/gal of GreenPlanet Root Builder Water was at room temperature. TEMP/HUMIDITY: A max of 89F and a min of 69F with an average of 79.9. - The max temp was only temporary while I had the tent open and was moving the ac unit next to a vent screen. On a new tent I would get an ac unit that has intake and exhaust hoses so that running the unit won't remove moisture from the air because it would be pulling from outside the tent. VPD was pretty consistently in a tighter range with the average being around 1.26. Whole week numbers> Temp - 79.9F avg - 68.6F min - 89.4F max Humidity - 63.8% avg - 19.0% min - 89% max VPD - 1.26 avg - 0.30 min - 3.20 max CO2: Floating ball is at 1 to 2. 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. CO2 tank ran out on Thursday after running for about a week and a half. I shouldn't have to swap out the tank this often, it's likely due to the fact that my ac unit pulls air from inside the tent and exhausts it out of the tent so it is probably sending the CO2 rich air out of the tent and the tank then has to run more often than it should have to. Again an AC unit with intake and exhaust ducts should help with this issue also. PAR: PPFD between 400-600. ISSUES: The ac unit and sensors seemed to stop working very well to keep the tent in a balanced temp/humidity state after I made some minor adjustments. I moved it again to be near an vent square and it started to work better, not perfect but workable. I only watered the plants one time with the largest amount of water to date but using a soil meter all the pots seem to have plenty of moisture still even a week later. A couple of the plants are not growing as much as the others and I think it's probably due to some over watering. I have been keeping the humidity pretty high so it seems like the plants are not using as much water as they could be. I plan on just waiting until I can see the slightest signs of droop in the leaves before watering again. I am also considering going with 24 hours of light. TECHNIQUES: I implemented lots of LST throughout the week.

This week consists of June 25, 2022 thru July 1, 2022 - Seeds were planted on May 27th, 2022 and they all sprouted on May 31st, 2022 (~4 days) Pretty good week with only minimal LST, it cooled off a little this week and temperatures were in the mid 80s so maintaining temp and humidity was not too challenging this week. 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. Will be swapping out the metal halide bulb to the high pressure sodium after this week since the plants have been in pre-flower for about a week now. WATER: June 26: ~750ml of 6.1 PH and 650 PPM. 15 ml/gal of Big Bloom 10 ml/gal of Grow Big 5 ml/gal of Tiger Bloom 2.5 ml/gal of GreenPlanet MediOne 2.5 ml/gal of GreenPlanet Root Builder Water was at room temperature. June 29th - water ~1000 ml each PH 6.1 PPM - oxygenated water Water was at room temperature. TEMP/HUMIDITY: A max of 88F and a min of 69F with an average of 80.9. VPD was pretty consistently in a tighter range with the average being around 1.4. Whole week numbers> Temp - 79.9F avg - 68.6F min - 89.4F max Humidity - 60.2% avg - 28.0% min - 86% max VPD - 1.44 avg - 0.43 min - 3.29 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 300-700. 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 600-700 range and some side leaves are getting in the 300-400 range. I might have to add some supplemental side LED lights to create higher PARs to fully take advantage 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.

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.

This week consists of July 8, 2022 thru July 15, 2022 - Seeds were planted on May 27th, 2022 and they all sprouted on May 31st, 2022 (~4 days) Plants began to show signs of either light burn or nutrient deficiency. The only changes I made was using the HPS bulb and I had started to add Cal-Mag. I was adding it every feed until I realized it should only be added once a week so I stopped for a few feeds until today I re-introduced it again. 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. Some of the branches are much higher than the rest of the leaves and have been getting a much higher PAR 1200-1400 range so I raised the light a few inches. WATER: July 9th: ~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 July 11th: ~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 July 13th: ~1000 ml of 6.1 PH oxygenated water July 15th: ~1200 ml of 6.1 PH and 1500 PPM. 30 ml/gal of Big Bloom 15 ml/gal of Grow Big 10 ml/gal of Tiger Bloom 5 ml/gal of Cal-Mag TEMP/HUMIDITY: A max of 90.0F and a min of 62.8F with an average of 78.8F. VPD was harder to maintain this week since it was in the high 80s and low 90s outside with the average being around 1.59. Whole week numbers> Temp - 78.8F avg - 62.8F min - 90.0F max Humidity - 52.7% avg - 21.0% min - 83% max VPD - 1.59 avg - 0.40 min - 3.20 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 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 started to show some signs on some of the top leaves of either light burn or some nutrient deficiency. I thought maybe it was me adding too much Cal-Mag but it seems to look more like a P or K deficiency the more I look into it but I am not sure so I will ask a question from some experts to try to figure it out. TECHNIQUES: I implemented some minor defoliation on some of the affected leaves and some leaf tucking.

This week consists of July 16, 2022 thru July 22, 2022 - Seeds were planted on May 27th, 2022 and they all sprouted on May 31st, 2022 (~4 days) Continued on schedule of 2 times do feed and then one water with only PH'd water. I cut out the Grow big since all the plants looked too dark green. 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.

Mostly consistent plants and buds. One plant became very purple I think because it was closest to the AC unit for most of the grow. One plant had some stunted growth and light green leaves but it made a great come back after flushing it with about 4 gallons of PH'd water and then specifically giving it increased nitrogen for a couple weeks. Some of the lowest buds on the plants were not as dense as I would have liked but I think if I had done some more LST and allowed the lower buds to get more light during flowering they would have turned out as nice as the top buds did. The plants had gotten rather large so there wasn't as much room in the tent to spread out all the colas as much as I would have liked.
