1000 watts cooltube by a old cool dude grow

i love u all welcome im a starting my first eva rollit up grow i grown alot of pot but new to da hydro wit help from my sons i will be okay

1week into flowering

pure grow pure bloom

aloha, you can get the light a lot closer with a cooltube, I have a 1000w cooltube setup too. If you were always having the light 6-12" from the tops you would have bigger plants. Easiest thing for that is yo-yo tension hangers, pretty much made for reflectors. Lookin nice though, assuming you mean 1 wk since you changed the photoperiod? They may not be done vegging, get that light closer!

yea my temp get alround 90 i have a cooltube hook up to a tds 100 6inch and a 6inch inline sucking hot air out wat ya temp like any pic and 1week flowering

they growing like mad look at the changes from yesterday

Why don't you leave one side of the cool tube open so you pull hot air out of the grow room?

If you don't want to leave one side open, tube it to the ceiling so it sucks hot air...

Or are you already doing that?

wow i would try that will the cooltube still remain the same

i mean will the cool tube remain cooler

there growing like crazy hps rocks


check it out friday will be 2week of 12/12

I would try two things with the cool tube.

1. try what repvip so you are sucking out hot air. The cooltube won't stay as cool as it is now, but I don't know if that matters becuase it is far away from the plants... however it would matter later as they get closer.

2. move the fan so it is pushing air through the cool tube instead of sucking air. It will make the fan work less and thus more airflow, and make your fan last longer. It is like when you blow through a straw vs sucking through it... you can blow more air than suck, haha that sounds funny. You don't suck mafio.

You could actually do both, but do one at a time first to see what helps.

Another suggestion is to try to turn the light at an angle more... the reason is that the intake ducting is making such a hard right angle when it meets the cooltube. I can tell it is crunched up against the wall, and that will affect airflow as well.

Lastly, you might need a bigger fan. For a 1000w in a closet like that you probably need at least a 6" fan at something like 400cfm, but that's a guess.

Are you exhausting the room itself separately? I saw the ducting sticking out of the wall.... is there a fan in there?

The plants look beautiful by the way... you green thumb is obvious. If you can get the temps in control that will be one awesome closet.

For some reason this picture is tiny and I can't see it... could you upload a larger copy, if you know how.


Sorry for doubling the word count on your journal, I like to type.

i will try that i have my other six inch inline fan suck hot air out the room but now workin as well temp hot ima try this as soon as my son get here got new pic one day away from week of flower and alot change

one more day well one more hour till two week of flowering and i c a lot of white hair on 6 plant wow i had two male and got three more plant that havent show sex cant wait till see bud bud i know i will in week 3 im use ing pure bloom and liquid karma and i have to say it doing good ph stay at 5.8 and temp at 90 but everything growing good

Looks like the picture from "turbo charge your garden " if I'm not mistaken. Its a good read but it seems that it really hangs on keeping the garden at 75 etc but I hear with co2 you want like 86. Anyway lookn good. I've heard reverse theory on the fan placement guess I'll have to go to the physics lab for that? Big fan in front of line or in back hmm anyway have fun till next time.
