1k watt heat question..

I wasn't posting pics to say "hey I'm the best grower with the biggest dick". Look at the quote I quoted when I posted the pics.

Plenty of posts of beer bottles as reference in lots of my pics in the Aussie thread, Scrog thread and even some smaller coals and plants with a beer bottle in Skunk and Shit thread.

Ive been growing since the late 80's (mainly outside). Have grown in the Kimberly dessert and still achieved decent buds. I aint the best grower and I don't know it all but its gotta be damn hot with no air movement for cannabis to struggle.

My point is people can and do grow in warmer climates indoors and they grow decent bud without AC or a sealed room and CO2. Wrapped that you have a great environment to work with but I don't have that luxury. And they can easily achieve 1 g per w using a single light source doing it.
EXACTLY this ^^^^^^^^^^

Maybe, though if you're paying more for ac than plant you can fit in your space, its a loss.
If the quality is there, but you have to run ac to fill the space, and dont gain a dollar, but lose several, its a big loss. Ain't a way around it.
Winter is an absolute dream here though. Heating costs me fuck all in comparison, and the yields probably 20% more. But only by the amount of flowers. Not the quality.
Ha ha winter is worse for me. I don't run a heater and rely on the HPS for heat. Spring and Autumn see me with perfect tent temps. rest of the year I swing from cold to hot.

Good enough is good enough for some .
You might be surprised at the increase in yeild when you pay attention to all factor.
Providing the right conditions will also make your plants finish faster . (Or in the time that they should)


Good enough is not good enough for me
I want it right, each to there own .
i agree, and i do try to optimize as much as my environment allows. there are advantages and disadvantages to growing inside. you have to take all the advantages to offset the disadvantages. we control the temperature, the humidity, the strength and period of exposure to light, we can make sure they get the food they need when they need it, and enough water to stay healthy.
the single biggest disadvantage is that we don't have the sun. now matter how big a light you have, no matter how many cobs or strips or quantum boards, they'll never be the sun. so do what you can to offset that disadvantage.

I’m not saying plants can’t grow in these very high temps. And when we are talking outdoor temps , it changes things very fast because the soil temp will be a lower then the air temp. In a room, it’s very hard to achieve this deferential . Once the roots n plants gets to a certain temp(depending on environment) photosynthesis stops, the plant then diverts its energy into coolin it’s self, and staying alive vs bulking up.

When the internal temps of the buds start to climb, this will make them stretch n be airy
Day here or there , you’d have to be pretty fine tuned into your grow to see a difference. But over time you will see it .


Every grower has to weigh pros n cons
In each space n setup, my veg isnt anywhere close to my flower setup.

No light will ever be the sun,
When I did grow outside , I do things very different then inside.
Inside the best we can do is manipulation of the plants to get the effects we want.
Vert is a good example.

I absolutely agree man. In a 20 000watt room, temps would be essential.

Space is a 4 foot long, 3 foot wide 9 foot Tall.
Originally was gonna use this as veg room for outdoor,
Turning it into flower room.
1000watt will be dimmed to 50-60% ( whatever the lowest setting is on my dimmable ballast)

Going to have a 6in 430cfm fan in there
The fan is going to go
Carbon filter —-> hood ——>fan ——> out window.

With a 8in passive intake at the bottom,
The room where it’s going to be intaking from is a constant 73 degrees.

My concern is even with venting out the hot air the inside temps are going to be 83+

So I guess my question is how much heat does a aircooled 1000 watt hps @ 50% dimmed produce?

Thoughts?
Wait ...pause whats the hurry...?

Summers coming up

IMO: go with the original idea

Use for germing and vegging

later in the season

use this closet as a light depo room

them come fall

reconsider as a flower room

by then you know exactly whats needed

and what to do

good luck

I grow for fun and profit. My flower tent is only a 4 x 4 so running a heater or AC would cut to much into the profits.
Wish the wife would let me grow inside the house.
look to the fish tank store for guidence

I have used 25 watt fish tank heaters with great results

inserted into the overly large pot..

normally 3 usg

but for winter I prefer the extra insulation of 6-8 usg

after all its the root zone I pray to

not the 'bush' ....lololol

good luck

That's a great idea!.

Yep root ball temp is key.

Only time ive seen airy buds that were not genetic was an indoor inner west Sydney grow were the temps in the grow room were consistently over 40c (104F) (a unit grow in Ashfield for those that know Sydney). So yes I agree heat does cause airy buds, may cause stretching etc. But due to me coming from being predominantly an outdoor grower you just adapt. Ya have to accept what the environment is and grow.

I think I read somewhere that the plant can regulate its leaf temp to 18c?? Please don't quote me and can handle quiet large temp swings and still do this. Guessing mainly through Transpiration. Hence the importance to being close to the charts on that.

This may be the same bud as earlier (next to the bic lighter...) or another one (it was a Scrog so lots this size.) check out the weight. I don't consider that airy? Not saying its huge or Cricket ball dense...But its decent.

I hope I'm not coming across as argumentive or anything and If I am I apologise. Id love a nice set up like you have. Just some of us have to deal with what we have and sometimes I think the more professional growers forget that it can be done, and done pretty well with less.

As long as I get a harvest and don't get busted I'm usually pretty happy!

It’s all good. Didn’t take it as argumentative or anything ,
Good to have discussions about things ,
How we all learn, I think that’s what’s most are here for .

Well I get decent results at over that..no problems.

I think most people who say these things haven't grown in warmer temps or use fans...Like outside, air movement and transpiration is key.
People indoor grow in Australia and South Africa and we see peaks of 40 plus c (104F) at times.
Its not usual for me to see 35c (95f) in my tent in summer.
I ran an aeroflo2 36 in a 5x5 closet and had temps about 91. But my rez temp was 65. I didnt have co2 i pulled 28zips
