Hi there,
I also get my info from experiece, most people, however, require solid quotes from famous growers to accept ones advice. I'm averageing 23g per under 3cfl's and frankly i'm too high to get upset about mistakes not happening in my growroom. I know I don't know it all so i hit the books to verify my first point which was that growth stops at 30c,
And your point about mexican outdoor was well made.
peace :joint: Bardo :joint:

I am sorry for the remark i made towards your girls. I did not know you were under cfls. N hey thats dang good for cfls. I personally never tried with cfls. I was just trying to make a point of a problem I ran into with heat in the 90,s and the end result was crap. had some nugs and little yeild. But ya know for the time effort and invesment im usually trying to do everything as perfect as possible. Everyone lets just keep it at 78 degrees so we all get sticky dank nugs:smoke:

stihgnobevoli - you got an ounce of dry weight from that one plant? take a peak at mine and tell me how much you think i get. I usually go by my own experience as well. that was the point i was trying to make was that i ran into heat issues before and my crop at end was terrible. thats all i was trying to say. my apologies. but i am curious. if your gettin an ounce of that small plant. then i should be yeilding a pound with these ones? right or wrong?

Without Air conditioner, no way to cool down room? Or maybe someone can ship cheap air conditioner to Latvia??? :D

if you use CoolTubes, with good presure in, then you will cool down your growrom!
the best CoolTube is called spudnik, from prima klima in chech-replubic

i got an ounce off those 2 small plants . if you started from clone and have that much room to grow in and i guess a light over 400w you should prolly get a couple ounces or more per plants.

ive done from clone before and triggered em right outta the clone dome. i usually got roughly a half ounce to ounce which was just one cola per plant. What was the strain? I love that bubble gum though. mmm. is so good. Ill be posting pre harvest pics soon in about a couple weeks. Im actually hopin for a lb out of this 4 mom grow under 2 400's. i think im going to get it to.:smoweed:

I think strain genetics plays a part also. Some plants such as the skunk 1 im growing doesnt seem to mind 90f temps. I keep the air flowing too. The stupid 120v ballast is kicking out most of the heat. My hood is air cooled. Im running 400w hps at 18hrs a day. Plants are a little slow growing but not sure if thats because of 18hr veg? Hes correct about the over fert issue during heat. Plants are 15in tall after 36 days from seed. Hoping for anouther 8-10in before flower. Never got over 90f so...?

I'll chime in here on my results.
I grow inside a closet under two 400 HPS.
The temps are steady at around 85-90 degrees and, this is with the door left wide open and a floor fan blowing in to the closet on high all day.
When I first started out growing in my closet, I had one 400 HPS but, I didn't have the door open. The result from that higher temp is that my plant was slower to produce buds and I had a profusion of leafy growth all along the bud sites. I have been told this is due to the plant trying to protect the buds by shielding them from the intense heat.
The clone which is growing alongside the original mother is quite different.
It is growing normally, filled with big thick buds and very few extra leaves.
There should be one fan leave at the juncture of each bud site, which is how the clone is growing. The mother which was stressed by heat looks like it mostly leafy material although there are some incredible nice nuggets underneath the leaves.

I believe through my correcting the problem, the mother has recovered and is about a week away from harvest. On the other hand, the clone which went in to the room about one month after the mother. (when I got my second light) This clone should be ready to harvest at the same time as the mother.

I think many small closet or cab growers go through this problem of high heat simply due to the cost of putting together a proper grow room. Eventually, grow by grow, we learn and hopefully are able to find solutions that are within our budgets.
I think that point is lost by people like jorge, Soma and Ed Rosenthal.
They have the money for the best equipment, a professionally constructed room(s) and long years of experience.

I believe this issue points to the need for ALL growers big and small to petition their governments to allow for cultivation outdoors.
I am a low-income chronically disabled patient and the stipulation placed on me that I must grow indoors is very taxing on my finances. I literally starved for weeks just so I could put away enough to buy my lights. Now I need to do without food just to buy an air filtration/circulation system.

All these issues could be removed if I were legally allowed to grow outdoors in my garden.

Here is another thought on growing different strains of Marijuana.

Growing a strain that naturally occurs along the equator in Canada outdoors, certainly will not grow as true as it would in it's natural habitat. Duplicating the equator inside a closet or grow cab is what I would believe is the goal. I'm assuming the same is true for growing strains which originate at the various increases in Latitudes.
I selected the two landrace strains found in my journals because of their original habitat.
I realize that there are many incredible cross-strains with fancy names but, my approach is that I wanted to know the habitat the particular strain is best suited for. Using that information as a baseline, I now can determine the optimal environment for these strains.
Same goes with soil and the level of nutrients and water available to the landrace strain.

If I had a strain of marijuana that was indigenous to Greenland, growing it under 100 degrees at 12/12 light cycle should lead to a disastrous result.

Does anyone know of a study, based upon strains and the optimal conditions incrementally at the known latitudes?

Im running the same setup. 400w hps. Closet open. Fan blowing in, fan blowing out. Runs 85-90f during heat of summer. My ballast kicks out some serious heat. I wont grow again in the summer. My next grows will be cooler im sure. Strain is a factor.

my box is getting upwards of 95 degrees..my house is set on 80 all day so its impossible to have a 4x4x4ft box with a 400w hps to get any lower or even close.. i have an air cooled hood with a 6 inch fan sucking heat out, (4) 2 1/2" passive vents and a 4" fan sucking air out of the box....I ALSO have a 6" desk fan blowing on the plants.. still in the mid 90s...One plant looks great and green with no ill effects but another is getting very leafy with little bud growth..someone on here explained how its the plant shielding itself from heat..im screwed...anyone know of a tiny tiny a.c unit?

Hi Samson06, I mentioned the shielding.
Here is a pic of the mother that got heat stressed and one of it's clone after I fixed the issue.

You can see the clone is doing well while the mother looks like cousin IT ;>}

Bigger fans. Im running 2 10in hi volosity fans. 1 pulling air in and 1 out. Plus a 6in hi volosity fan pulling from my hood. And a tower fan outside the closet. 24/7. Open the window at night. Anything i can do. No more summer grows.

you would have to post pics to get good help..
but I can tell ya 80 deg ambient outside the box is your main problem,,I can see the difreence in my cab-------

for every 1 deg I change the house thermo at
, I see a 2-3 deg diffrence in cab temps
if I had mine set at 80 deg my cab would prolly be in the 90's

winter temps are definitely the answer

All i can add to the thread is that for the first time as i have a room with no ac running at the moment, i have been growing plants with temps upto the 90's, 83-92 seems about the swing, i have not seen as fast growth but no way in hell growth has stoped, they look great, ill get a pic later, also i will add that the plants are still veging, so i cant coment on how fluffy the buds would be at this temp. Also the large swing is from the 18/6 light schedula and the fact that in the day its far hotter.

The only thing i noticed and is good addvice, as was mentioned earlier, is that you have to be carfull not to over feed as the plants are using allot more water than they would be at 78.

Peace
