4x4x6, 600w... Do i have to ventilate???

Ok... My situation is that i have a 600w running... Humidity is fine...

i have no in/out ventilation.... NONE.... Only air coming in is throught the flaps... And no place for it to come out... Temps outside the tent are 65-67f...

my temps got a bit higher than my first trial and went up to 87f. I will get an extraction fan but i cant afford it till next pay.... Can i continue like this for another week????? Please help.

how long was the trial? I think it might become an oven

I agree I bet the temps will just keep climbing. Growth slows/stops at 85-ish I believe so yes you need ventilation and an air cooled hood would also help.

I would at least leave the tent door open a bit and have a fan blowing in, perhaps at the light until you can get a proper ventilation setup.

Do you have access to a window mounted air conditioner? If you do then jerry rig some duct work from it to your hood, or at least into your tent. Maybe a friend could let you borrow one?

Even if your tent temps stay usable, your bulb can still blow if it gets to hot in the hood.

I would at least try and like rig a trash bag/plastic bag to the back of a fan and hook it up to some duct work to pull a little air into your tent. Or even just some kind of fan putting some positive pressure into your tent, and having one side of your hood open with duct work coning out the other side so that you are moving a little air through that hood and out.

Yeah i was worried here to.... After 18hrs with hps on the highest it got was 87.4f....


So for anyone else reading this thread....

IF you have a 4x4x6 tent with and hps600w inside and a 30cm oscillating fan with no intake or outake fans and outside temps of 60-65f your tent can stabilise under 90f.... I know because mine is doing it right now... I have no air cooled hoods or any ducting or any fans other than the fan circulating the air around the plant... My plant looks healthy and with the help of a dehumidifier when the humidity gets high i could go like this to harvest... But alas im getting a fan in the next few days so i wont have to.... Was an interesting experiment though....


so to answer the question..."do i have to vent a 4x4x6 tent with 600hps... The answer is yes.... But sometimes no "

When the dehumidifier runs it adds more heat.

You need cool air in, hot air out ....

Your temps are 90f at the plant tops while the plants are tiny.

If they were full grown, most of the plants would be frying (90f is already frying, I'm just pointing out that it would be even worse than that).

If they were in flower, you would have whack buds.

Fortunately it sounds like you're situating your ventilation system soon so you wont have to find out first hand if I'm right or not.

Ventilation sorted...crisis averted....although i maintain what i said.... And NO frying took place whole thing looks good.

Passive intake through lower flaps 4" extraction fan temps are steady at 70f.

flowering now.

i have a 4by4by10 tent i have no air going out but i do have a duct connected to my AC but no exaust realy the holes are barely open but i do feel air coming out and they are doing fckn awsome 3ft tall 2half feet wide ive bin so worried i know i need ventilation and if this post is to show that u can do it without u can, but why would u wanna risk it at be worried about the temps and humidity and everything else that cums with not having ventilation. the tent is also in my bedroom so i wonder if when me and my women are sleeping the c02 were breathing out is helping cause i do lock my door when i sleep. maby thats why thier doong so great.should a plant be 3 ft tall after 1mnth veg and im not talking that tall lengthy type of plant im talkn a bush thats 3 ft tall... any oppinions?
