Haha, that guy acts like your weed won’t grow if you don’t know exactly how much power your light is consuming at every minute.
I didn’t see any leds burn up there. Most of the drivers are labeled to their output specs. Ie 150 watt driver is going to send 150 watts to led modules. But the power supplies aren’t 100% efficient at converting energy either. So when you put a power measuring device in the input side, you measure what the leds are consuming plus the amount of power losses in the driver.
Also worth noting that the dimmer controls output current, nothing on the input. It’s just a potentiometer that is separate circuit within the driver. I have no idea if it has stops, but most do. If it doesn’t should just go back around to zero and start getting brighter again. But it won’t create any magical increase in power, and I seriously doubt mars sent the fixtures out with larger drivers than the modules can handle. If they did, sounds like would be warranty claim to me. Either way, 50% output current isn’t going to neccesarily be half of the input power the light consumes. So the whole method is pretty bunk from electrical theory standpoint. And if you were shooting for half power, there’s only a real small difference in being +/- 10-15 watts.
Well @dbrn32, I did not dim the lights yet, but I dropped to 18/6. What I didn’t expect was that it would impact the temp and humidity so much… really good bump to 50%rh w/ no humidifier yet, and temp stayed at 22c vs a normal 25.5. So only being a week under that light I’ll try the new schedule and see if that rhythm will be stable.
Maeve took 500ml of water today. Dose of nutes too.
Other two haven’t been watered for two days and are fine. I assume the humidity bump is based on the plants breathing so I’ll keep a close eye on them in the next few days.
Feels like I need to bring the soil up to the pots edge and then train. But i need those pots first. I tried the grow shop and they don’t have fabric… ah!!
Yes I’ve found that it’s hard to pull branches out and secure down if dirt isn’t up at least close to top of pot. I was too far along in 5 gal buckets to do anything about it but you can fix when going into bigger pots
Bernard is getting some low stress training. She’s bee rotated about 90 degrees so far. No branches big enough to pull the other way yet. She was also FIMed last week.
Had a great visit to the grow shop today. I can confirm that I found the right dude’s to support the new habit, er… hobby. I got a carbon filter but also the advice that I should be careful drawing air before I have the humidity high enough. That means I’ll probably wait for the installation of the filter until flowering pushes the girls to breath out more.
The real fun of the day was training. Lots of LST love here, and I’ll share the photos for my records and your input… please feel free!!
A steady supply of CO2 overrides humidity concerns unless you are at humidity extremes. I’ll attach a VPD chart to help you understand where the best levels at various temperatures are.
At least 1 of those girls look like they’ve had a bit too much nitrogen and needs a break.
Looking really good other than that.
Edit: Sorry. I’m not able to upload the VPD chart at the moment.
