Yeh, that video is excellent as in "required reading". I've attached a copy of Westmoreland's thesis. Re. "dialoging back" - Bugbee was asked in a Mr Growit interview about 48 hours of darkness and Bugbee replied, without hesitation, that he'd leave the lights on for 48 hours.

Getting into the home stretch!

Cut a hole in the sides of the tent and install the vent cover. It's similar to what @Gemtree is recommending. There "has" to be a… [time passes] This is the tent you've got: You're fine. The tent is not air tight. Even if you close the flaps and push the velcro tight, air is going to get...

"Surprise!" - yeh, that's both a head scratcher and a pain in the ass. My thinking is that the answer is "perhaps" depending on the amount of light in the room in which the tent is located and the direction of the light. You might want to contact their customer service people or you can use a...

It could just be 2024 technology vs 2019 technology. Migro's new lights are the most design to hit the market and the spectrum is weighted heavily in the 660 region. If you're hitting the plants with the same PPFD, it could be something as simple as that. Having said that, there are a huge...

Yeh, I think you mentioned that before. Well, it will give you a lot of "quality time" with the plants.

Per above, there are a lot of things that are pretty cut and dried—keep RH and temp in certain ranges, keep nutrient strength at EC X, and get your plants to Y µmol of light. And there a lot of things that are very, very hard to teach. That was a change for me because I've never grown anything...

Best source I've found for VPD is here. Pulse was the first generation of VPD hardware that I used. Inkbird was next and I've settled on AC Infinity. AC Infinity has an excellent IR gun because it can be calibrated and you can change the emissivity factor. The latter can make a small...

Yeh, you're getting hammered by that, eh? I had chatGPT run some numbers and it fell into the "measurable but insignificant" category, even with the big "bucket" that I have (39" x 14" x 20" that holds 28 gallons of nutes). Re Southern AG — I switched to that from Hydroguard. I hear you with...

Interesting about the heat. The driver for the 4500 is removable, right? I see the set up in the first picture. It looks like the lights and the plants are really close to the same size. I think I see what's going on (helps to look closely). Re. temps - latest research data is to the temp of...

If you raise the temperature of the tent that will increase VPD and it will also significantly increase photosynthesis. Are you supplementing CO2? With that high a level of CO2, you're getting a good boost in photosynthesis but increasing PPFD will give you yet another boost. The SE 4500 is an...

Congrats on the grow! Excellent results, especially for first time hydro and you made it through some brutal temps, too.

If you're getting good results from the Migro light, there's a strong argument to buy more of that product. The decision, for me, is to buy the products that fulfill certain price and performance criteria. What the company might or might not have done is not something that I am able to judge...

Hah! "I when I was a lad…" ;-) "I been using google deep ai its not as good as chat gpt on a good day but its consistent."— I get the idea that's the key-to understand how a particular bot "thinks" and then work with it.

The Canadians call it "deking" someone as in "that picture deked me". ;-) Canna has a good reputation and, since it's a product line you should be able to get input from other growers if things go sideways. Re switching to DWC—I've never grown in soil but I like DWC because there's no mystery...
