Very nice grow CM, I can only hope my expansion turns out so well.

CoralMafia, how hard are you driving those cobs though? CoBKits, I can handle the additional heat, but extra nutes, well I'm just not sure... I run no till living organic in SIP boxes, I do not use bottled nutes of any kind, I dont even PH my water, my microbes do all that for me. I adhere to...

What is the WPE for 1.7 and 2.1? All the literature Ive read only lists .7, 1.05, and 1.4, always assumed it fell off hard after that. I know 1.4 is 56%, much lower than that, you might as go DE HPS.

Thank you! Do you personally think its worth it to drive it that high? Right now @1050 I am sitting at 40w sq ft, and 24.4 par W.

Is that extra light going to translate into a measurable increase given the extra power used? I know my WPE is going to go down a bit @1400mA, but do you think its a worthwhile change/investment? Thank you very much!

Think I will need the middle light, or lights on a separate driver/pot? Unfortunately, I have yet to buy a quantum sensor, so I'm not even sure if my current setup is giving me a hotspot, but I'm thinking it is, and increasing power would make it worse. And is that 50w sq ft from the wall, or...

I have a couple 3x3 tents and soon a 4x8, what is the most i can run without running into problems? I already have a 9 CXB3590 light in a 3x3, running @1050mA, can i run that same light @1400mA in a 3x3 tent? The heatsinks are rated to @1400mA, and i will be using a pot, so I can ease into...

I use a dimmer, so I would gradually bring up the lights when moving the plants into flower tents. Also, if that hot spot in the center is that big of an issue, I could just run three drivers to the light, and keep the center one on its own driver. Then I could either run three 1400mA drivers...

I am already running a 9 CXB3500 light @1050mA in a 3x3 tent, was wondering if it would be worth bumping that same light up to 1400mA? Would that be too much? I know my WPE will drop down to roughly 56%, but the extra output would more then offset that would it not? I am running a scrog, so i...

Thank for all the work everyone has put into this, just wired up my 9 CXB 3590 light running @1050mA. Have two drivers, so used a 50k pot, and 5 1k resistors wired in series, could not find a 5k resistor locally. I bought the resistors before i understood what they were actually doing, or i...

I have been thinking about giving the whole crop a peroxide dip, then blasting the whole lot into dabs. When harvesting/trimming i cut away all the visibly affect parts, so would doing the above be me best bet? My guy who does my dabs said as long as i do a peroxide dip before, it will be fine...

Yeah i saw someone recommend hydrogen peroxide/water dip, or something like that. My buds are already in the curing jars, can i still dip at this point? Or should i wait till after the cure, so i don't mess that up, then dip, and dry? If that is not possible, would it be safe to blast some dabs...

So this last grow i was not running a sealed room, 3 days of rain (80-90%RH) led to spots of PM, i increased airflow, heavily thinned the canopy, (scrog) bought a dehumidifier, and used skim milk 1/9 ratio. I certainly held the beast at bay, but to a certain extent, the damage was done, it was...

I see with this method you open the jars if your RH is a bit too high, like 65% after stabilizing, leave jar open for few hours. But how often do you burp the jars regardless? Thank you!

What about using those two way humidity packs? It sets it at 62%, is that good for long term storage? And in a pinch, could you not use one of those for curing, if the product was still just a tad bit too wet, and you did not have time to come back to it? Slap a pouch in a jar and let it cure...

Thanks, yeah it just went up to 66%, ill take it out of the jar, and test it tomorrow. How much of a rise from ambient RH is a good indicator that its ready? Over the course of one or several hours? Yeah i read it took 24 hours to get a proper reading, but I don't want to risk mold by leaving it...

SimonD Thank you so much for all you have shared, I really appreciate it! I also enjoyed you shutting others down, who talk out their ass, highly entertaining! I do have one question for you, and I do apologize if it has been brought up before, I am a bit less then half way through this thread...

Having a intake vent sort of eliminates the rooms negative pressure, still a bit, but not a much as with no vents. However, the end result is the same, you have non-conditioned air going into your grow space, full of conditioned air, and your conditioned air is being sucked out the exhaust. The...

The number one reason why we run sealed rooms is humidity, if your not worried about humidity, and your not worried about wasting AC, go for it. If you want some passive cooling though, your best option is to cool your lights with a closed loop system, so your room is still sealed. But again...

If humidity is not a big deal, you might be able to get away with venting, but it would still waste AC. One thing to remember is that plants sweat lights off, and if your not somehow dealing with that, it will cause problems late flower. In the winter i have no problem with venting, cause RH is...
