hush grows up! 1000w MH/HPS in 4x4 tent

[Jhhnn]

Let your experience with this strain be your guide. Do you normally LST the clones you flower after a few days? What sort of stretch do they give you?

With all those growing points, stretch shouldn't be a lot, I suspect, and you do have decent headroom & good light penetration from the 1000W.

I really have no experience with that style of growing, but I'm sure I'll need it with some of the strains I want to grow so I'm following your efforts closely.

Maybe just let 'em grow for a week, re-evaluate, figure it out from there.

Well, this is the first time I'm doing any training at all, with this cut. Every time I've grown her before now, she was done single cola style, flowered immediately after rooting.

But she really doesn't stretch all that much, so I'm going to just let her grow upward now and evaluate it from there, just like you said. I'm thinking that it's likely I've gotten enough growth tips now. There's probably about 10 to 15 on each plant.

I suspect I'll be flipping to 12/12 in under 2 weeks now. I'm getting excited!

Looking great hush. Subbed for this one

Very nice, hush. It's an entirely different approach than what I've taken so far, which is to just let 'em grow. Mine is def the way to go with autoflowers, and I like the easy way so far with strains that don't have mad stretch. There's something aesthetically pleasing about untrained plants that I like. OTOH, I'm sure I'll want to pinch back some of the hazier strains I want to try if only for manageability. 12' monsters are simply out of the question.

It'll be interesting to compare your yield & total growing time with the way I've been doing things.

Live Well!

the hot/warm air is not good for the fan > after a while, they will destroy him

"no one" builds a cooltube-system on this way -.-
sorry dude... check it!

postscript:
even if they have not connected the filter (in this pic) > it's impossible to use this
leave it there? or they change it!
I don't care...
but it is better to use for you and to see for us

believe me! (and all other "pros") thx! make it good and better!

^ I see what you are saying, but this is the way I have always done it with lower wattage, and it has always worked before. Plus, I see many other people doing it this way as well. The problem with the way you are suggesting is that I would have to have 2 fans, for a dual stage ventilation setup, and that seems unnecessary since using 1 fan seems to work? I have the exhaust fan turned down 50%, so once I connect the filter, I'm sure it will restrict the fan some, and I will just increase the fan speed. Thank you for your advice! If I end up having problems with heat then I will certainly take your advice into account.

Jhnn, stay tuned man, because I'm about to flip them to flowering, so the comparisons should become evident soon enough. I've got some auto seeds I need to grow out one of these days... maybe I should pick your brain! But yeah, the main reason why I'm doing all this training is not for lack of vertical space... it's strictly for yield. I am looking to maximize my yield out of this tent without having to pack in dozens of plants. So far it's looking promising... it seems that the canopies of all 5 plants just might actually fill out the entire footprint, the way that a SOG of this same clone would do. Of course, I will have to stake up all the branches, but I'll cross that bridge when I come to it.

impatiently waiting for those flowering pics hush

So am I dude!

Hey if the grow is running cool with just one fan... thats all good.
and cheaper and whatnot

However, I did find and post this link earlier on two fan sysytems for cabinets and tents. Look at example #4...

One fan to move air out the light area/ the other fan just to pull for the carbon scubber. You get better pressure thru the tube

look at example #4

4. Two Stage Cooling/Ventilation with cooltube and scrubber

 

[[]310TEC[]]

idiocy -.-
no! nobody (in europe) pulls the warm and hot air in to the fan
that's illogical!!!
you must pull the exhaust air in to the filter > and after press the fan, the air in to the cooltube > and out
this is only the right method!

LOL

but i dont want to teach people... make your own style and get lucky with them...
sorry!
good luck dude still good grow!

 

[hush]

Okay dude. I'll let you know when this stops working for me.

 

[Jhhnn]

i really like the way you used a tent inside an air conditioned room. The tent gives good light control while letting a lot of the heat out, reducing the need for airflow thru the tent. The fact that there is no direct air exchange outside the house , or very little, is great for odor control, as well. It also eliminates the need to alter the house.

As your babies grow up, you'll still want to have odor control, just because you don't want the home's interior to reek of reefer. You've clearly planned for that.

For future reference, an inline fan should last longer on the cool side of the light. It's a common design feature on industrial fan cooled machinery that I service & repair. Another positive to doing things that way is that you can directly connect the fan to the filter so that there's only one joint where smell could possibly bypass the filter. Any other air leaks in the ducting only allow small amounts of filtered air to spill back into the tent. With industrial machinery, that feature allows for better dust control.

Just a different way of looking at it that might prove helpful in the future.

Thanks for the heads up. Yeah, I've heard people make the argument that the fan should be before the light, so that no warm air is being blown through the fan's motor... and it makes perfect sense, too, in theory... But I've known people who have been doing it this way for over 20 years now and they never had any fans fail earlier than they should have. So it makes me think that this is one of those things that, even though the theory is sound, in practice it doesn't always work out that way.

Now, if it does present any problems, then you can bet that I will make the necessary changes. I will buy another fan if I need to. I will reposition things if needed. But I generally wait until somethings not working before I fix it.

These are great suggestions, great advice. Thanks guys, it is welcome.


I think I will go fill my CO2 tank this weekend, and get that going. It's about time. I'm really impressed that the plants have grown as fast as they have without any supplementation all this time!

Hush,
I have had my exhaust fan pulling hot air outside my tent for two years and it is still running strong. I have a tent and a homemade cab, they both have air cooled hoods which I connected vents to one side of each light and ran them outside the tent/cab and used a Y connector to attach to my fan. This way my lights are not increasing the temp in my tent/cab dramatically and I ran the output of the fan to a window to completely get rid of the heat/smell from the room.

As long as your AC in the room is maintaining the temps you want, your setup is fine.

 

[hush]

Thanks Bud. Yeah, that's how I'm looking at it, until further notice anyway. I have been monitoring the temperature and humidity 24/7 since I started this grow. I'm monitoring inside the tent as well as the room the tent is in. And things are staying nice and cool! If anything, I'm almost concerned that the room is dipping down to 65* during lights out. I've heard that's too cold. Oh how I have longed for the day when I would be concerned about my plants being too cold instead of too hot!!! :yay:

 

[Bud Buddington]

Are the temps dropping because the AC is on all the time or does the weather cause the temp drop?

 

[hush]

It's because the AC is on all the time. I mean, it still cycles on during the night cycle. It's not technically on all the time, lol. But yeah, I guess I could hook it up to a timer that is synced to the light timer.

 

[Bud Buddington]

Hush, I bought a temperature timer for my AC and it is set to 80 degrees. So basically it will turn the AC on when temps get above 80 degrees in the room and shut off when the temp is below 80. This does cause the AC to turn on and off more frequently but seems to hold the temperature very stable. I got my temp timer on Amazon for like $30, it was so worth it.

I was having the same issue as you were having before I put this temp timer on. The AC was running 24/7 and the room was getting into the 60 degree range at night and early mornings. Anyway, good luck on this grow. Everything is looking great!
