I'm bring this thread back from the dead because I am searching for the same answers as the OP, and didn't find all of the information in this thread I desired. I am in hydro under current, 12 plants, 6000w, C02, 80 temps, 50% RH, House and Garden full line, 100 gallons of water. I'm after...

I am using H&G in a 100 gallon under current system. As far as draining/refilling goes, I drain 1/2 way through veg, again at the end of veg, again 1/2 through flower, again 1 week before harvest to flush. My veg time is four weeks and flower is 8 weeks, so I flush the system at 2 weeks, 4...

2 weeks, 3 days into flower at this point. Would a sulfur burner do the trick and be OK now? It's spreading too - and fast. Should I cut some leaves off? Maybe just the ones that are most affected? Would something like this work? This place is close to me. Thank you for...

Nutes - House and Garden running at around 800-1000ppm. C02 is running PH: 5.5 - 5.9 Water temp: 70F Room temp is 80ish, but I understand that it shouldn't be an issue due to C02? Humidifier is running all of the time. It does look like a powdery mildew.

I'm having some problems with my plants that are in a UC XL13 (12 plants - 13 gallon buckets) Some of the lower leaves (that don't get my light) have a white powdery substance on them. It is "spotty" on the leaves. (1st pic) Same system, same plants, some have some weird holes in the...

There's a reason why Sun Systems only sells 10' extension cords for their reflectors. Add that to the 15' cord that comes with it and you get 25'. I'm not an electrician, but I wouldn't go much further than 25' if you can.

Most cabinets that you can by are set up with the carbon filter on the exit. Also, most have the lights sealed from the rest of the cabinet. The lights are air cooled separately from the the main cabinet. So you would have an air intake for both the lights and the growing area, but the exit...

Thanks for the awesome feedback. That is definitely very helpful. Not running c02 at the moment, but maybe I will. Your pics don't seem to show up in your post?

I have a room that is 15x15 with 6K watts over 12 plants. I'm running the UC12XL13 under current system with a 1/4 HP chiller that keeps the water temp at 68. The lights are air cooled with two 8" vortex fans pulling air from the room through the carbon filter, through the lights, then to...

This is all very insightful, incredibly valuable feedback. Thank you so much for all of this information. A soon as the system arrives and I get it going (less than two weeks) I will post up on here with pics so everyone can see. I ended up picking up one of these for $230 shipped...

Yeah, that 165 tank is $145.00, but shipping is $185.00 for a total of $330. The local feed store had a tank, but it was over $400. I will check into the cube tanks though. Thanks!!

So, I took the plunge and purchased the UC12XL13 unit from CCH20. This is a 12 plant system with 13 gallon buckets in the XL configuration supporting 6000 watts total. I have 6000W using (6) 8" blockbuster hoods Titan Helios 7 Light Timer 240v Titan Kronus 4 Environmental Control...
