quick n00b question re: heating & humidity

does the HID light provide the heat for the grow room too? or do i need a seperate heater/source? also as i need to control the environment inside the tent best as possible i was thinking of buyin a humidyfier because i heard they like it humid.. but im sure i also read somewhere that seedlings dont like it humid or it causes root or stem rot. does this mean i should only turn the humidyfier on after 5 nodes? thanks in advance :thumbsup: are there different preferable temps for the different stages ie seedling, veg and flowering?:rastasmoke:

The HID does put out quite a bit of heat, but is it going to be enough heat to keep your growroom at the desired temps and what are your growroom temps going to be like when the lights are off? This will depend on the area where your growroom is located and what sort of extraction system you've got. I'd do a test run over a 24 hr period and see what your temps are like before you decide to buy a heater or humidifier. I don't think the optimum temps change for the different stages of the plant. As far as humidity goes, i thought higher humidity was good for seedlings, but you should lower humidity in flowering as it may give problems with bud rot.

Good luck!

i don't mean to sound like an a**hole but, have you even looked here Cannabis FAQs / FAQ , Recipes, Medical Marijuana before asking something like this?
believe me, experienced growers will just ignore you if they think you're too lazy to do your own research. the thing is that that question shows that you've done very little of your own research.
people will be glad to help you, hell, they WANT to help you, but only if your willing to help yourself.
so, go HERE Cannabis FAQs / FAQ , Recipes, Medical Marijuana and start doing some reading, when stumped, ask questions.

bozo,
peace, love, dope

yeah ive been reading loads actually. im just tryin to fill in the gaps for the info i couldnt find...

that link was fairly good thank you.

and oddly enough, that link has been there, near the top of the page each and every time you have come to the site. it's labeled 'Cannabis FAQ's' to make it easy to find.

you are sounding like a regular here Bozo lol

i have three teens too lazy to help themselves so i get a little testy when i see someone with the ability to log onto the internet and, seemingly unable to think for themselves, LOL
not that i'm talking about you canabaloid, don't get your nose out of joint.
the thing is, i believe in the philosophy contained in the statement:
'give a man a fish and he eats for a day, teach him HOW to fish and he eats EVERY day', so when i point a newbie at the FAQ's, i'm trying to teach them HOW to fish, if i just gave them answers, i'd just be giving them a single fish, then, the next time they need an answer, well you get the idea.
anyway,

During the winter, yes, the HID will provide some heat when the lights are on. (too much during the summer months, lol) Likely not enough to keep the ladies cozy and warm during the winter, though. (especially when lights are off)

I live in the desert, where humidity is around 9% during the summer, and I don't own a humidifier. Every time you water your ladies, you are adding a bit of humidity. Overdoing humidity at any stage and you risk mold, but buds are more susceptible.

Keeping temps within a 15 to 20 degree range is preferable. With my outdoors flower shed, I have problems with this twice a year. During the winter, I try to keep the temps between 50 to 70 degrees, during the summer months, I try and keep them between 70 to 90 degrees. Were I just growing inside my house, I'd keep the temps between 60 and 80 degrees.

BOZO: Three responses to this post, and you never answered a question.

Too late. Especially considering the fact this isn't the first time in the past few days, that you've ragged on a member for the assumed offense of not looking the info up.
Now normally, I agree that one should use the search function, but you offer no insight or help beyond that. Just strife, and an implied superiority in your tone.

So...my recommendation is: You keep reading, and when your actual knowlege base is equal to your implied knowlege base, you'll be more qualified and perhaps know how to respond in a less flippant and unhelpful manner. (ie: by then, perhaps your responses will be helpful)

like i said in my last post in this thread, i'm trying to help him understand he can help himself if only he will try.
and i don't pretend to be anything but a rank beginner, i've just read the FAQ's.
of course, i could just blow these posts off and just be selfish and not post ANY answers, just ask simple questions, the answers to which are VERY easy to find

well dont get me started on GUI lol im a graphic designer (and ive always found forums not so easy to navigate!) i just never noticed that link . i noticed the stickys but never really saw that link b4 u showed me (obviously). suprisingly tho it has the most useful info, so imo it should be more prodominant. anywho im really not too fussed. all i want to do is gather the info i need...end of.

and its not like once i have the info and confident it is competent and correct i will pass on the wisdom should anybody else be in the same situation im in... or was in hopefully ill be able to say once i get the hang of it!

suffice to say JABOZO ppl learn at differnet paces and in different ways... maybe you will learn THAT one day!!

i mean i know there n00b questions and theres total n00b questions!!

besides isnt that was this forum is here for? anyways....... ive just noticed theres loads of big posts goin up and id just like to say i have the info i need now.... thanks rusty and thanks JAB (even if it was a bit back handed)

in future ill try to be less of a n00bilus maximus!!! thank you!!! :cool:

Sorry for the hijack, canabaloid. I've got a quick off-topic response for (aptly named) Bozo...

As I stated, I've seen these responses from you in few posts, and now three responses in the same post saying the same nothings, and offering no substantive help.
What, have you taken it upon yourself to be the wise and honorable member, and rag on fellow newbies till submission?

If your only two options are to either 'blow-off' a post, or rag on a fellow member...I'd blow-off the post, and let those with correct and appropriate answers do their thing. There are plenty of us here willing to do so.

Anything else you'd like to argue about, let me know...I'm around here a lot, and haven't been in a good argument all week. :jointsmile:

no no be my guest... i mean that link did help alot! but like ive said its not prodiminent enough (not a jab at the forum thats jus my opinion for what its worth...)

didn't mean to create a problem and i sure don't come here to argue.
i just thought you'd benefit way more from that link than you would from me and my very meager knowledge. in the future, if i can help, i will. good luck with your grow, i wish you much success.
oh, and as an aside, i chose that name to remind myself to be humble

bozo,
peace, love, dope

Patience is a virtue. That is what makes canncom different from that other big site with the pot leaf wallpaper. We are oriented towards getting new medical growers up and running. I do NOT like to see people getting testy with noobs who are just trying to get information (although you can flame noobs repeatedly giving shitty advice all you want, within the rules of the site of course). If you aren't going to help, just spectate, and if you've got a link, great- but please pretty please be more gentle about it.

Canabiloid, 'humid' is relative- Plants don't like it arid; they like SOME humidity. Your goal as a grower is to match your humidity to your temperature fluctuations so that the relative humidity stays about 30-60% in veg and 30-40% in flower.

The reason that you are having a hard time finding that info might be because adjusting your humidity is so dependent upon your grow style.

Hudson and Rusty are leading you in the right direction. Do a test run and measure your high/low temps and high/low humidity. If you can, go into the room in the dark period and look at the %RH- if it is reading significantly higher, you will want to add exhaust.
Why?
Simple. What is dew? Dew is the moisture that WAS held in the warm daytime air falling out as liquid water when the air temperature drops at night, and cold air cannot hold as much water vapor as warm air.
Did you know that you can get dew indoors? It can condense on your buds, causing rot.
This is why you want to keep your temperature day/night numbers within ~10-15 degrees of each other, and be certain that you are still running your exhaust fan when the lights are turned off.
Adding plants will add humidity, as they transpire the water that you give them into the air, and as they grow, they use and transpire more- so your numbers will change over time, and you'll just want to keep an eye on that. Different styles of growing also add moisture to the air- if there is a large surface area of water or moist medium exposed, as with a hydroton ebb n flow bed, that can be a source of evaporation.

Bud rot is likely to set in, especially with dense strains, at %RH over 50. So avoid that.

Now that's an answer, lol. :thumbsup:
(guess that's why they pay you the big bucks, eh Stinky...?)
