thanks for the help hey is that what they run for the thing that control himidity cuse i thought they might be a little cheaper my question now is do yall think that i need it
Do you mean a
dehumidifier? That's something separate. What I showed you, was something to control your exhaust fans, a space heater, and a portable A/C unit. Did you look at those links? Shop around, I'm sure you can get that stuff cheaper. Of course, I didn't search for the best deal for you. It's likely that no one here will do your shopping for you.
Do I think you need it? How would I know? You haven't given any information about your grow.
Please don't take this the wrong way, and I don't mean to be gruff, but you are going to have to do a little more work for yourself. Begging for help isn't really going to provide you with enough knowledge to grow. Right now, you are coming off as incredibly lazy, which is probably why you haven't gotten too much help so far. Did you look to see if you could get a cheaper one? Go to Google, type in dehumidifier or whatever and look at the shopping links. It's Internet 101 stuff.
At the end of the day, no one is going to hold your hand through this. There is no magic list of "what you should buy" to grow. It's up to you for your individual situation. You have to learn how to find this stuff out for yourself. Read the growFAQ link at the top of the page. Do forum searches for info. Buy a grow book.
Any of those should give you an idea how to get started.
Good luck, my friend.
