great work ec! glad to finally catch up with ya, although only briefly.

those new cups are definitely a LOT nicer than the old ones...gotta work on getting one of those myself LOL

man, this thread is poppin like 2009, I havent logged in for a week and I'm like 5 pages back!

Hey Family, just a little PSA...
I've been doing some weeding around the casa and have def seen some powdery mildew.
Last night I saw a single white spot on one of my teens in the nursery. I want to think it was just a dried spot of nutrients but it looked pretty filament like when I put the scope on it. It was a small enough plant I could dip it in a gallon of eagle20 and this particular teen won't get flowered for a long time so I went nuclear.
I'll be on high alert for awhile and I encourage y'all to do the same

You're doing good works every day GT. Thanks for passing the word.

Hypnotoad testers will be passed out to the SDF fam the next time we get together. Genetics are a combination of my Mindmeld(GROM x Xena Goo) pollenated by the male Terpene grew out from Grow Tech's recent masterpiece AD-E x AOC. Should be lots of straight purple gas.

I had powdery mildew issues until I started cutting all my weeds back more regularly. It floats on the breeze I tell you..

I've had some time to smoke the AOCxADE and I can tell you, its a lot more comfortable at 10 weeks and less eye openingly potent than it was at 8 weeks. The odor (orangey, dank-funky alien dawg) on freshly ground flowers is strong from across the room. Its still very "zoney" but more warm/happy. The 8 week flowers made me a little nervous/awkward in public situations and I was generally worried about my interactions with non-stoned people. At 10 weeks, you can cruise around all day long with a big dumb smile on your face - much more my speed.

Hello Fellow San Diegans! Could use some of your experienced brains and would appreciate your help. I am in need of a cooling solution for my growroom.

I live in scripps ranch and i built a growroom in my garage. My temperature ranges from 79 degrees (lights off during the day) to 90 degrees (thermostat kicks on my exhaust fan at 84 degrees but lately outside air is 86 degrees so days like those are when my exhaust fan seems to be on all night with lights on.) It averages 84 degrees with lights on. Right now i am in veg with four plants so i dont think temps are having a negative effect so much yet but i expect it to get hotter with summer approaching.

I don't like the idea of having my exhaust fan constantly on whenever lights are on because it brings my humidity all the way down to 20% and renders my humidifier useless. Im also trying to be as efficient as possible by going with the option that consumes the least amount of power. My exhaust fan uses 200 watts. Im wondering if i could use an air conditioner to bring temps down while using less electricity since my grow room is well-insulated. I am hoping the AC can bring temps down to 80 in veg and 75 in flower without consuming as much power as my exhaust fan does. Im also hoping it can blast out cold air to bring temps down quickly and stay shut off for awhile since my growroom is well insulated until temps rise again.

So my options are:

1) window AC inside my grow room? this sounds like a great logical solution but the fact that i am in a grow room built inside a garage complicates things. There are no windows in my grow room so i would have to modify the window AC to exhaust the hot air into the garage while it draws in fresh air from the outside. Not sure if this would be more inefficient than the next option...

2) buy a used mini split 1-ton on craigslist for about 400?

3) swamp/evaporative cooler? How would these work in my environment? totally out the question?

4) portable a/c - pretty sure i should just not even consider these as they are supposedly inefficient?? would appreciate my fellow san diegans input!

PH issue? Seeing too much yellow in my teens, coco medium, house and garden A & B, cal mag and silica blast...I havent got a PH/PPM monitor so I'm going for golden with my PH color, it used to work just fine but I'm thinking its the problem now. They should have plenty of food, not overfed but just right to be honest, just doesn't look like they're taking anything up. Is gold the color to shoot for, or should I be going for a more yellow/green color. Thanks

 

[Caligreen1]

Just dawned on me that I have been following the guidelines by adding A&B, then I PH, then I add cal mag and silica.....That has got to be changing the PH! House and Garden recommends additives after you PH but I'm sure they're referring to they're own additives, not cal mag and silica blast...Here I go to check the PH on the solution I've been giving them.....Doy!

What light(s) are you running?
IMO you'll feel the AC in your electric bill. The question you have to ask is " will the improved quality be worth the cost"

Air conditioning units use much more electricity than fans do. My room AC unit that is made to cover a single bedroom uses 1100 watts. Small bedroom units are usually 500-900w. I would imagine anything you're using to cool a whole garage will use at least 1500w.

Swamp coolers add humidity. Don't go this route unless you've got great ventilation/controllers.

Why not run lights that don't create as much heat? (LINK)

Hi thanks for your response Im running 16 CXB3590 COB LEDs in a 6x6 room that is pretty well-insulated. Yes, i think you are correct in what I SHOULD be asking. As I really have no idea if my plants are okayy with the 86 degree envinronment theyre sitting in when lights are on. And with suummer approaching I imagine my temps will go up even more? (not sure this is my first grow). And i am still in veg. I am thinking i will want to drop temps to 75 degrees ideally, when in flower?? would flowering in 86 degree be a threat to my yield/quality? And yeah, i tried to plan out my ventilation so i wouldnt need AC but now that im running my first grow im starting to think my ventilation won't be able to bring temps down no matter what if all its doing is pulling 80+ degree air in from outdoors

Hey i think we may have the same lights? I have 16 CXB3590s in a 6x6 space. Temps are reaching 86 degrees lights on with my 200 watt 8" vortex on full blast. My grow room consist of drywall/r13/foam insulation board. I was hoping to throw maybe something like an 8,000 BTU window AC in it without needing it to be on 24/7 since i have insulation?

My COB LEDs are running passive right now and using a infrared thermometer the hottest heatsink gets to around 110degrees F. I was thinking about adding active fans to cool the heatsinks but someone said this actually wouldn't lower temps in the room.

As far as swamp coolers go, arent they pretty much counter productive VPD-wise? If they cause humidity to rise and they don't work well in higher humidity, doesnt that mean they are probably not ideal for gardens since we want high humidity in veg especially at higher temps?

EDIT: Just found a 6000 BTU window AC for 30 dollars on craigslist. im thinking about jumping on it. not sure if building some type of ac box will be a PITA though

Interestingly, kind of, I have the opposite problem, too much humidity.

I'm indoors in a 5x5 tent under a 630 DE CMH. I have lights on at night. I leave two mesh covered windows open and leave the main door open to a moderate gap during lights on for temp control.

I have a fan hooked up to a humidistat controller (or whatever it's called) to turn on the fan if the humidity gets above 75%. When the tent is in lights out, that fan turns on every ten minutes or so. Even with that, when I check the min/max reading for a day (separate sensor), I commonly get 85% or more.

My max temps are usually mid 80's.

I got a second fan that I can turn down to as low as 30% that I'm going to try running all the time to see if that helps keep the humidity down. It draws 35W at full power, so that's around 16-17 W at 30%

I have 2 clip on 6" fans and a 9" rotating fan for air circulation but I'm getting pretty nervous about PM

Waddup bro
Here's the order I would go:
1) silica-this is ALWAYS first
2)calmag
3)pH
4)A then B or B then A

Gold is still good
I think any issue you having should be coming from the order your adding the silica...GT might be able to weigh in on this.

 

[Caligreen1]

So you PH before A & B? Then you don't PH again after adding A & B? Thanks Rob

 

[subrob]

I do...but in the beginning I had to dial it in...meaning if it wasn't right I would add a little more..not sure of the science but I think it has to do w the pH agents affecting the base nute...it only takes a few waterings and you'll have each mix dialed..
If others' experience is reviewed I would say your issue stems from not adding silica first...again..not claiming to know for sure but I've seen a lot of posts about it.
Your welcome bro

 

[Grow Tech]

I've used silica as pH up so def post base mix. It does cause a white milky cloud to form so I get my res mixing and then dribble it in, then mix vigorously. I assume the cloud is stuff coming out of solution but I feel like I mix it in fast / well enough to not be an issue.
I think pH-ing before silica is a mistake personally wold pH at the very end but I don't have my mix down as tight as Sub.

since i got a new bluelab truncheon meter plants were getting healthier.

switching to 17 watt 1600 lumen 2700k and 5000k cfls.

40 new crosses to weed out.

out these the budder og x chem 91 sk va and purple bubba cookies will be nice.

 

[Hammerhead]

Curious, why not just ph after u finish adding everything ??. Never had any issues doing it this way but I'm not using House and Garden.

 

[ECtraveler]

It's been years but when I used H&G (coco line) it didn't mix well with Silica. No matter when it was added in the process the PH would spike over a period of 24 hours.

Hey newguy, maybe try a baffle around your led bases, vented directly. Like a box with the leds poking out of holes. Keep the heat from the led bases from ever getting into the grow space.
