By chance any one could answer this. ok.. Im currently growing in a ten by ten by 7.5 tent using 4 1000 watt mh. 1 750 cfm exausting two 1000 watts outside of hole building. Another 800 cfm exaust on the other 2 1000 watts. 2 oscillating fans adjacent each other.14 plants. Purple kush feminized. Three og kush. Dwc. Portible ac unit 14000 btu i believe. Its exaust is also exausted outside of building.. In room temps are 70 to 73 degrees. rh is 40 to 55 percent roughly.. Outside of tent is 55 degrees. Im using a elemental 1750 gph i believe and a 900 ish gph elemental. 6Pots connected to the 900 and 8 pots connected to the 1750 . pots are all painted white/ tops and bottoms/ leaves me to my question. Why are my res temps 70 72 degrees when i have fans blowing around the room at a atmospheric temperature of 70 to 72? Could these pumps be blowing hot air in my reservoir?
I just figured this out today with someone's help, I had my air pump inside my small tent so that was ~78F air being pumped into the rez. http://forum.grasscity.com/index.php?/topic/1329219-My-2Nd-Real-Grow-Attempt%2C-W--Pics%21-Bubble-Cloner-clone-Machine%2C-Dwc
That makes sense. Im going to try that. Outside the tent is 50 so that should work. If not then my pumps are too hot eh?
Most nutrients I have used leave a thin film on tubbing and sometimes the stones, I always change my res once a week and clean off film on tubing and stones if any is present. G
Quick question are you using any kind of root conditioner and I see you painted your buckets white you don't have any light penetration into your buckets right? As far as maintaining a bacteria free environment root zone by dutch master is a awesome product I recommend it to anyone, it's only 1ml per gallon so it lasts a while and leaves your roots pearly white and kills off bacteria. Just good for thought. G
I have used a .5 grams per watt per month as the optimal point , what you have is over kill. with ONE 1000 bulb I was getting .468 grams per watt. the room was 8 x12 with 28 white widows. Temp is depends on the strain to max output, RH at 80 % ave temp at 90 deg F. System is run with a by Yellow AdBlocker">computer control for water, light, co2 injection(own controller set at 1750 ppm with a 50 ppm +-) Only did it for a few years :<) I would back off with ONE bulb , Always remember its better to grow for 20 year than get caught for one year. Invest in good ph ppm meters. Done right you can harvest a year in advance with in 3 days. Know your strain (note no "s") and you will do the best. To quote the cops "the best system we have ever busted" now have a CA permit but still under the 99 plant limit. yes I am the sanclem of years ago
And half pound aint bad but it aint good either friend on a light you could get double or triple that potentially
Ah yes, the same sanclem that used to go around telling everyone that HPS ballasts are only good for door stops and everyone should be flowering with MH lights? I remember your yield claims back then, and I remember that the pictures you posted never supported your claims. The best system they ever busted? You are still telling that story? Must have been some small town Barny Fife. I'm the same str8jacket from years ago (on the overgrow forum).
Half pound? You realize that 1000 grams is 2.2 pounds right? 468 grams just a few grams over 1 lb. Anyway, sanclem's claim to fame (according to him) is ..468 grams per watt PER MONTH.
Switching to an outboard rez will save you lots of trouble See my DIY Mini-Me thread in the hydro section
