Man, and I thought I was the proud owner of some BlackDog technology…it’s supposed to out perform a 450HPS, but first grow? have no perspective on what one of those can or should do either…I thought that I purchased a full spectrum, commercial grade light with excellent PAR values and some really good canopy penetration capabilities. I’d love to know what you’d recommend as comparable for the same or less price because I really was impressed with mine so far and was thinking about picking up a 400 from the same model. How does my light look when you use 420 watts in that equation instead of 210? I’d love to know the nuance between the two outcomes but I’m not sure what equation you are using or how to interpret it?
I planned on growing 4 plants in my 3x3. I currently have 3 growing. I originally purchased a BlackDog 600, and when I was running trials with it my tent ran up to 95 degrees and the heat made my fans run constantly. It was also cooking my root chambers through the coolers keeping them in the mid 80s. I tried to cool things off and tweak it, but I came to the conclusion that the light was overkill for my space. I did not think the heat was appropriate and the fans running all the time meant I would have to sacrifice using the CO2 supplementation. Another problem it caused is that my root chambers and pump take up a lot of vertical room in the tent so I needed a powerful light that would accommodate what I have left for growspace. My plants ground level is waist high. So now with the 200 my fans keep the temps between 78 and 82 and the humidity 45 to 55%. The CO2 shoots up to around 1800 ppm every other fan cycle and keeps the average level between 800 and 1200 most of the time. With the 200 watt light all my other gear plays together like a symphony.
I still have the 600 and have been curious about if I could get away with it during the winter, but all of my girls grew 2+ inches in the last 24 hours with the system as is. My blueberry (which is mostly recovered from some pretty bad note burn/deficit?? I’ll try and get some pics) was standing tall at 25 inches last night when I took the pics. I just got home from work and took a peek and she’s at 28 inches and my three girls are drinking about 1 1/2 gallons of nutes a day right now. Do you guys think it would be wise to push them any harder?
