Lots of defoliation on multiple days, started Purpinator, Copper and Neem oil treatments sprayed on, new CO2 system w/ controller. Raised CO2 PPM to 1200-1600 range fluctuating over 2 min.
Scrog working well. Pistils finally appearing.
Could use some advice on my CO2. I feel like my room is pretty well sealed. Magnetic strips on left and bottom side (permanent seal on right). My fresh air is constant, on low, and colder than the grow room,
at around 70F. I have it blowing in at floor level. As you can see in the pics the fans are pointing up into the canopy. The CO2 emitter hose is attached to the back of the wall fan. My theory behind it was that the CO2 would rain down onto the canopy from above as the fan is directed just across the canopy to ensure it reached the Gmommy Purp on the left. Once it falls through the canopy, the cold air layer at the bottom-combined with the upward directed fans, would push the CO2 back through the canopy, and cycle again. My CO2 system engages at 1200ppm, still it steadily falls to around 1100 and begins climbing. The system shuts off at 1250ppm but still climbs to around 1600ppm, hovers for around 15 seconds, and steadily falls again. Total time the system runs is 2 min, every 5 min. It seems excessive and Ive already been through ~40lbs of CO2 in approx 16 days. Any thoughts are appreciated. (BTW my controller does not have a photosensor. So I have it controlled by Alexa to run on the same routine She runs my lights on. Which makes setting the CO2 impossible as it resets on power loss. Im happy with the presets but just giving all info)
Ran Florakleen flush for 2 hrs between nutrient change.
Good growth. Seeing some buds start to form. I have been snapping off fan leaves here and there when theyre directly over a bud, blocking light.
One last MgSO4 foliar treatment when first pistils showed.
Getting a massive humidity spike just after lights turn off. No heat from light causes temp to stay under limit to engage the exhaust. Ordered an additional exhaust fan to run on humidity controller.
Having some algae on the main part of the roots that frequently is above the nute level since I top off every other day. Tried adjusting nutrient cooling system, didnt work, returned to run continuously. Getting ~70F reservoir temps during light cycle. Still using hydro guard and have been spraying H202 on the algae during nute changes every Tuesday.
Hoping to see massive bud growth in the next few weeks. Have 4 weeks remaining until the scheduled final flush. That obviously may change.
Still getting a massive humidity spike approx 5-6hrs after lights out. Exhaust and dehumidifier cannot keep up and RH spikes to 80-82%
Brown algae bloomed in buckets.
Did 24hr flush with Ph 5.8 water, Florakleen, and H2O2. Flush water was almost black afterwards with a Ph of 7.1.
New nutes and added a mycorrhizae. Hopefully will get better results now.
Added a/c hoping for lower Humidity and temps. Temps are good although average humidity has risen but humidity spikes have decreased dramatically. Side effect of a/c is increased use of CO2. Used 20lbs in 4-5 days. CO2 system empty, switched to homebrew at 475-500ppm. Contemplating turning off the a/c during light cycle and only using it during the dark.
The Great White 1000% solved the root slime/algae issue. Cant recommend the stuff enough.
While trying to adjust my floor fan, I knocked the gallon CO2 homebrew jug off the light and onto the Bubba Kush Plant. I lost my main stem (I topped and ended up with 3 equal stems after it repopped in the center where I thought I topped well enough) Didnt have my drying room setup nor was it flushed but I ended up trimming 3 broken stems. Drying was embarrassing, couldnt maintain temps lower than 75F during the day and 69 at night. The only fan I had to use actually raised the temp by 1-2 degrees. Humidity stayed between 40-45%. I was afraid to add the humidifier due to the higher temps. Definitely dried too quickly but oh well. They were casualties, not flushed, dried in 6 days, but never molded. After trimming I got right at 1oz from what was broken off in the incident.
The rest of the week was uneventful. Started paying closer attention to the trichomes. Noticed in the beginning of the week that they were 100% cloudy and ~20% amber. I have extreme anxiety, some Hybrids and a lot of Sativa strains at high THC and terpene content actually make it worse. So I wanted to shoot for higher amber count before harvest. End of week was around 30% so with the lower half of the tent peppered with dried sugar water, I decided to flush. Just water PH to 5.8 with Florakleen. I used it for some nutrient change 2 hour flushes with good results.
Started Flush on Tues 6/13/2023. Haven't decided whether or not to do the 26-48hr dark period before harvest but will decide before the 48hr flush is over. Either way. Air conditioner, humidifier, and fans are ready for the drying cycle. Will simply trim most of the few larger non sugar leaves and hang the rest upside down as a whole plant. Aiming for a 12-14 day dry time.
@Canna96, Im contemplating it. I like the immediate plant response you get with nutrients in DWC. I can visually see the roots being oxygenated and any root issues. Less pest, fungus, and bacteria issues. But it is a PAIN to maintain nutrient temps and levels. And as of late, moving the whole plant/lid to do top offs, nutrient changes, PH/PPM samples is tedious, scary, and risky...
I either have to drill a 1" hole and add a plug in the lid to get samples and pump in/out nutrients. Also buy a cheap borescope to see the roots when needed.
Or Im switching to coco.
Im most likely going to have to dry in this same space. My drying tent is only a 3x3 and with the size of these girls I dont think it would be large enough nor easy enough to control enviro conditions. So Ill have a few weeks to decide before the next grow. Also thinking of doubling my grow area and doing 4 plants. The added plants would double my time spent doing nute changes. A lot to think about before mid July when Im done drying.
