When it comes to temps, the main rule by which I try to operate is to maintain no greater than a 10 degree swing throughout the day.

Is that the swing DURING lights on.... or from lights on to off? temps start at usually 65-70 @ 11 AM... by 3 PM, I'm up to 85-90 or so... but at 11 PM,lights go off, and I open all the windows turn on the fans, and bring the outside in.... so, if its 40 out.... my room'll get down to around 50-55 degrees.... round 3-4 AM I seal the room off for the night.... from 4AM-11AM the room heats from 55 back up to 65 where is where I find it in the morning.... rinse and repeat....

So the question is not the swing during the day... but the swing from day to night.... I am trying to recreate the outdoor... indoor....the best I can...

I don't think it affects the thermal mass of the 20 gallons of soil per SIP bucket.... the inside chamber of air should insulate good enough for just a few hours of good cold per night.....

I appreciate anyone with personal experience giving their 2¢

ALSO:
Too hot, though, and your plants metabolize in overdrive, which means they'll need more water/etc to keep up with the increase in photosynthesis..

that is one point of consideration in why I raise daytime temps....... faster growth... more water expelled and used...

I want my flower room to feel kinda like October.... if that makes sense..... at night... I guess its august during the day....

I like my temps to be as close as possible during lights off/ on.
basicly trying to recreate spring & fall in the rooms ..... 75 to 80 during the day & 65 to 75 at night .... closer to 75 i can get the happier the plants seem to be . i get drooping if it gets to cold @ lights off .

 

[unclefishstick]

theres as many theories on this topic as there are growers....for certain greenhouse grown flowers they do a "cold air dump" right before lights on but otherwise keep the temps fairly even between day/night,and theres plenty of science on the effects of temps on stem etoliation and all that other botanical stuff but what it really comes down to is how much money do you want to spend chasing after those ideal conditions? me personally i run my flower room exhaust 24 hours a day and only turn on the intake a hour before lights on and run it until an hour after lights off,the veg room runs 24/7 as far as intake/exhaust fans.but as far as any actual control over the temps i have none really,my flower room was in the 90's over the summer pretty often and it got close to 100 in veg a few days,never had any problems aside from needing to water more...

 

[dansbuds]

I actually like the way this new set up is running . I walk into the main room of the grow section of the attic where all my big & small veg is & its warm & muggy .... temps hover around 80 & humidity is up around 50 . then i walk into the flower room & its a touch cooler & the air seems dryer & i can't believe how well its circulating now compared to 4 x 8 I had everything stuck in before !!! its great

but what sux is .... i doubt very much it would work come summers heat !!! but hopefully ... i'm outa here by then .

By "temp swings throughout the day," I meant over the course of 24 hours -- which means, yes, the difference between lights on/lights off.

As to the desire to replicate inside exactly what's outside, I feel like that's sort of debatable - that is to say, I'm not entirely sure that all outdoor conditions are superior to indoor conditions, simply by virtue of the fact of "nature is nature!" Just kicking tires - food for thought.

Also, just a quick thought, if you're getting lights-off temps down to the 50s. You'll get a quicker finish, and depending on the genes, some colors, but the quicker finish may come at the expense of yield. (The question then becomes, "Is it worth it to finish the crop sooner/start another one sooner, or let it run its normal course and squeeze the few extra grams out of this run?" .. And I think the answer probably involves a consideration of scale of the operation itself).

I appreciate anyone with personal experience giving their 2¢

My personal experience has been that I get more stretch & heavier yields when I keep the temperature within a 10 degree range over the course of a day. HTH

Zacklee! I think the challenge becomes keeping up with it. When I was running bare bulbs (in 3 gallon smarties and blumats), I had to keep the blumats damn near wide open, because the room was high 80s/low 90s during lights on.

I want my flower room to feel kinda like October.... if that makes sense..... at night... I guess its august during the day....

Are you near the end of your flower cycle? If you're going for the "re-create fall" deal, you could consider cutting the lights from 12-on to 11- (or even 10-) on, 13 or 14 off. (This'll also have the same potential yield sacrifice as the colder temps mentioned earlier)

Again.. Just my

 

[Seaf0ur]

I use 20 gallon sips with 4 gallons or so in the res's so they can drink all they want to....

I have some near the end, and some just starting flower.... so, no consistency there either.... I think I'll dial back a touch.... bring it at least within a 15 degree swing.... little bit warmer nights...

appreciate it.

Good post Silver!

I was told the same thing that SILVER just said. You want Your temperature differential to stay within 10 degrees. Like Unc said, in most commercial greenhouses, they run a ZERo degree diff. Or pretty close to it. To much diff and your plants will streeetch. I think the temps that dan posted are pretty much ideal for most strains. Around 76-78 for lights on, and around 68 for lights off is what id want ideally. Maybe use slightly cooler water towards the end of harvest. That will also help bring out the purples.

I had a "O fuk" moment today. A couple kids that just got off the school bus were walking in front of my house and i heard one of them say, "It really smells like a skunk right here".
So that was the last straw, it scared the shit outta me. So i just got back from the hydro store. I grabbed a 6" x 24 "Can-Lite" Air FILTer. AS most of you know i dont know anything about air filters. Is this a decent brand? They only had Can or Phresh filters and these were about 50% less. So i got the Can 24 for the same price as the Phresh 16 woulda been. Good or bad choice?
I did get it for a $155 out the door, im not sure if thats good or not though

It says its good for 2 and 1/2 years, but I'm guessing the gg4 will cut that in about half.


And in the interest of full disclosure, i had just got done smoking a joint of OG. So he coulda have been smelling that. If thats the case, the air filter wouldnt have mattered in this instance anyways. But i still needed to get one anyways. So whatever.

 

[thewhitelotus]

i think the can lites are supposed to rival the phresh filters for size and weight. im not sure how much carbon theyre loaded with but i run a can 33 and im on my 4th cycle with it. no issues here

 

[thewhitelotus]

My room temps are around 77 lights on and drops to about 66 with lights off! Fit the screen in to check height and decided im going to take about 2 inches off each leg. whatcha guys think?

 

[pappy masonjar]

I think its lookin good!
Rom Diesel eh? I have a few Grapefruit Diesel (Grapefruit x somas NYCD) seeds from them. I havent grown them yet. Ill be curious to see how those turn out. Even if it is a different momma.

All depends how that strain stretches.

 

[thewhitelotus]

this is my 4th run with Rom Diesel. It doesnt stretch too terribly much so im going to train/weave for the first 10-14 days then let them go i think.

Giant battery/ Inverter

Giant battery/ Inverter

I just got my Home Battery back up system wired up. I ran oversized cables from the battery to the Inverter. And Hooked up the battery tender, to keep the battery fresh at a all times. When I use the Battery, I will use a more powerful charger to re-up the battery. It would take 50 hours to charge this gigantic battery with the tender. I ran a couple thousand watts of 120 volt through the invertor, and it purred like a kitten. It has five fans on it and they rarely went on. First test was a total success. This thing would runna 400 watt t5 rigg no problem for awhile. Hell, it would even run a thousand watt sodium, and a few fans for awhile, 161 lbs, 250 amp hour sealed deep cycle marine AGM. I love it!

Nothing exciting here at WhiteLotus farms tonight....coors lights n dollar tacos a little later!

Is anyone using one of these?? I was going to get it for the tent. Third I thought you had some of these ???

Gavita Triplestar 600 Reflector

 

[thewhitelotus]

triple star? thats a new one to me! I know he uses the Gavitas but that almost looks like a new design. At one of my remote locations i have an EPapillon which is almost identical to gavita, but supposedly dissipates heat better

 

[thewhitelotus]

nevermind....i see its simply the reflector and not the whole unit. Does this unit take double ended bulbs like the normal gavitas?
