temp question

what is the optimal temp for 3-4 week vegged plants, I'm sure I have seen it around here before but am too lazy right now to dig through the site? Thans in advance for your wonderful answers. Also I have another thread on here about how many plants to grow under 1 600w hps and 1 400w hps simultaneous above a 4'x6' 7' in height grow space, any answers to this would be appreciated as well, here or in that thread. Thanks again.

c'mon guys I know the answer is out there.

anyone?...

Yeah they most probably will be OK .
Being in the Pots the Roots tend to be the problem.
In the ground the roots stay cooler.
The pots will heat up , especiall black or red pots,
A big stress on the plants,
Watering 2-3 times a day may be all you need to so.
Put them in a shady spot in the heat of the afternoon.
It was in the 100s here . all the last week and this week.
Those plants in smaller pots started to suffer and show signs of heat stroke.
When planted in the natural soil, it would be no problem at all.
The genetics and all the rest come into equation..
Evaporation is higher in the heat, this leads to a potentially lethal salt build up.
The soil chemistry changes with change in temperature.
For example plants in 6 inch pots will have heat stroke
Plants in an 8 inch pot will not stress at all

Two days of hydroponic nutrients, followed by one day of a clearing solution, will help prevent salt build up,
and has been working great for SWIW, to controll heat stress. As long as the roots function, it will be OK.

Sea o green is a good thing but the name Sea o Green is Sorta Bull shit

The method SOG (Sea of Green) is good and sound , but we do not really want a sea of green

We are after buds not green

Sea o Buds, is the killer deal. Right?

No one wants a lot of leaf snd stem,

Another Item SWIW disicovered is burning lights 24 hours / day.
Is not that great, because it takes much longer to induce flowering.

If the plants Veg 16 hours light ./ 8 hours dark , They will be induced easier and mature faster.

By flower induction , I mean once you go to a 12/12 light/dark cycle.
Plants grown in 16 hours of light will begin flowering much faster than 24 hour vegged plants.
Once again it is not the Vegetative stage that has value, it is the flowering and budding, That is where you want to be. Managing buds and not leaf

There must be a basic structure of stem and leaf to support the buds. but other than that the vegetative stage is a bother

Using 16/8 instead of 24/0 for light /dark cycle, you save another 1/3 on the power usage.

That is my personal opinion, which may or may not be of use in your situation

A higher Wattage light will penetrate deeper into the canopy of plant material.

SWIM grew some 15 footers outdoors , the sunlight only penetrated about 12 inches beyond the surface of the plant.
Once SWIW stepped inside. close to the main stem, most of the inner area was stem and dead leaves, weeds did not even grow on the ground under the plants
A 15 foot plant is at least 10 feet across the base.
Most of the volume was empty space, and sticks.

Just an obvious sign to the police . Paranoia was intense , never again will SWIM grow like that.
At harvest there were lots of 20" 24 " long teminal buds.

SWIM watched them grow above the eaves (9 feet) and they just kept growing, , SWIM had to butch the tops, for the sake of his sanity,

Limit the time in Vegetative stage, and
maximise the time in Flowering cycles.
This saves energy, time, money
When Flowering the lights are only burning 50% of the time
more energy savings

400 watt HP sodium - 9 to 16 square feet - 9 to 16 plants
That is for plants 2-3 feet tall
1000 watt HP sodium - is good for 25 to 36 square feet - 25 to 40 plants

That means at lest 1 oz / square foot-
Sea O' BUDS

optimal temp is 70-85. they can survive in higher temps but i dont really think its good for them.

Tempereature Optimal . is probably what the Dutch are using ! hey ,

75 degrees F

Nope not true..

The DUtch have humidity problems, they keep it cold to prevent "damping off"
This is where a fungus attacks the stem , where it penetrates the soil.
Plants grow faster at higher heat, up to the point thatthe protein enzymes denature.
At 115 F they grew super fast.
It does seem that buds grown in the heat are more Airy( less compact) then those in a colder climate.

Water
Nutrients
Temperature
Light
CO2

Are what make the plant grow.

At 60 degreesd F a plant barely grows at all
At 120 degrees a plant is also not functioning well
The spot in between is 80 degrees F


If I add another 10 degrees , up to 90 F because I live in the desert , and am partial to warm
90 F - is my guess at optimasl temperature

One grower of seeds in Holland, says the best is a cyclic temperature range
from 75 at the cool side to around 90 at the hotest part of the day
Just as rbahodosingh suggestesd in the above post

thats bull. optimal temp cant be 115? are you an idiot or something?

Dude,wtf are you talking about with all that SWIM & SWIW stuff,is it a misspelling or does it have a meaning .

i think the guy is just an idiot or something...

I cant get up into the high 80's or my plants will experience heat stress & growth slows,in the 90's my plants would be hammered,if my room temp was 88 degrees my canopy temp would be near 100 degrees

The perfect temp for my room is around 78 degrees.

yeah i thought it was somewhere around there. this worlock guy said 115f is optimal temp... what a jackass... someone is asking for a legitimate answer and he would give someone an answer like that........

I am no idiot

What I wrote was
115 F, outside , in the natural soil. July, the plants wer 15 feet tall and growing faster every day, I have photos

Now that I think about it
I guess I am an idiot, for bothering to post anything that differs from your opinions

Thing is , I have proof , and I have done what SWIW and SWIM said .
I said repeatedly, your own personal situation is going to be different

I don't care to be called an idiot or a liar.
I thought this was a forum where discussions are held to find out what is really going on.. That is how you learn new things, not trying to defend the EGO.

Enlighten me, I read what you wrote
, I am in agreement with your temperature range, for the situation that is indoor, hydroponic, lights , artificial media, CO2 helps a plant deal with the heat.

A plant growing in a planters pot will .... on and on

I live in the damn desert, So me and heat are old adversaries \
heat is the name of the game , here

I have a degree from the College of Hard knocks, you must do some dumb things to graduate from there, and I can make fun of myself.
I treated you all with courtesy and respect .

I am not into flame wars , Once enjoyed them, but Flaming is too time consuming,
I would rather play guitar and smoke it up.

Which is what I am going to do, instead of this

As Alvin Lee sang,
" I'd love to change the world,
but don't know what to do,
so I'll leave it up to you"

rbahaddosingh ?
Wierd name, you never do say anything except head trash.

Do you have a thermometer in your grow room?

A 1000 watt HID will bring the heat over 85 F , unless your cooling it down


75 F optimal temperature, what a laugh.
waste of nutriemts, lights,

What a moron
