600 HPS Cool Tube Grow Light System

[criom]

pharmacan-

thats insane, your plants are going to be so huge you prolly wont even be able to see the light! are you going to build it in the same room as that one or another room in your mansion? seems like you have a really big house from the pics

i cant believe they even make tights that big, a person could fit inside that friggin thing. why dont you sell them on ebay or something? id buy one.

i would very much like to see that thread, i think ive searched the forums for every cool tube post ever but i dotn think ive seen that one you speak of.

will do on the "way cool" technique, my bookmark file is getting waaay tooo big.



that is awsome that you can grow for medical reasons (awsome that they allow you, not that you have medical reasons) are you going to mount vertically for flower? or stick to the same setup as your veg cab only a bit bigger?

and wtf you gonna tell the neighbors about that one? that you run your own isp now?

cant wait to see that build thread...ill be printing that one out for sure

hahaa i love buying equipment....NO :P

ive heard that temps in the 90s are ok for co2, but this summer it is really hot and it easily slips into over 105+ if i dont keep an eye on it. i dont think that is safe really...considering the wood on the outside of the closet gets so hot it almost hurts to touch.


the plants can barely handle 95+ too....last time i didnt have to trim the top fan leaves off after harvest....because they burnt off..

so yea i think i need it a little colder...



is a dehumidifier needed for 45% humidity even in a sealed room? i thought that was ideal. maybe i got bad info...

This isn't the one I was looking for, but check out this giy's verticle garden.

....still searching for the one....

holy crap
that grow is nuts! it better end with an outside shot of the ufo he built that in....

my god..

Well, I couldn't find the thread I was looking for. This guy had a closet about the same size as yours and he had four or six plants and a vertical cool tube and when he was done the entire closet was packed with plant growing right up to the cool tube.

But your closet is tall enough you'd probably want two vertical lamps. LOL that pesky equipment thing again.

My "mansion" - roflmao. I've got a three-car garage and I'm using one the spaces for my grow op. A lot of my neighbors have built offices and shops in their garages, so there's nothing out of the ordinary to be building in my garage. From my garage, the only thing you will see of the grow room will be the walls, a door and the backside of the air conditioner.

I'm not exactly sure what the grow room will be. It might be a "clean room" for semi-conductor assembly. I'm not quite sure what a semi-conductor is, or even if I'm spelling it right, but they sure sound like something that need to be put together in a "clean room, don't they?

"But your closet is tall enough you'd probably want two vertical lamps. LOL that pesky equipment thing again." AHHHHHHRRrrrggggggg

3 car garage is still bigger then some houses ive seen...but thats an awsome space to have for sure.

ahahaha yea a "clean room" for your semi-conductor sounds right
although they could take that to mean your making porn in there....
which is another good exuse too...


vertical is starting to make more sense to me since the footprint from the tube seems to be alot wider then a normal reflector...not that ive ever seen what it looks like on a large open space.

but i like the way it looks too, like part of a space ship.

thanks for digging for that thread neway, itll pop up again i hope

Hey Al - check out this page. Rock.Steady figured out how to post pics in-line, the way you want to for your cloning photo-essay. He's the guy to ask about it.

Hey, this is SoCal - one's as good as the other. imp:

jeezus, I take the Queen's flamin' birthday off and I come back to 240 message per hour scroll!

Al's instructions said to take big clones so that's what I did. If this comes down to the blame game, I'm not leaving him any outs. LOL

If big clones with thick stems don't work better for you than tiny little snips with the leaves cut in half (the only POSSIBLE way cloning can work, I was told 10-odd years ago... ), I'l eat my hat and BBQ a couple of felt fedoras for dinner. Fat stems root faster and more profusely. Thing is, the old (pre-HID lighting, mainly outdoor) grow guides didn't want you taking cuttings from mainstems as those would produce the best buds. Cuttings were best taken from lowers that wouldn't produce much anyway.

the humidity stays at 45% (i dont know why) and the temps rise to about 90-100,

If you have a second hygrometer lying around, do a quick comparison, make sure none are lying. Happens from time to time.

Could also have an awful lot to do with this curve.

Notice what happens to RH when you're approaching 38-40C (100-105F). The amount of water you need in the air to increase humidity rises logarithmically.

The air just might be able to hold all the transpired moisture the plants can put out between 3-hourly ventilations and yet not exceed 45% at 90-100F. :jawdropper: (but it's a dryyyyyyyyyy heat! )

Astonishing. Wouldn't have expected that.

I've run CO2 before, but always have had dedicated aircon units set for about 85F, which dealt with the humidity- or so I thought. Seems high temp alone may have been enough to control the RH... but these ops were 8 and 10kW, impossible in the spaces used without aircon, so I don't have a comparison base.

ive done one run with it and seen a 30-40% increase, so it seems like i could really pull alot if i had that last lumen/temp golden number dialed into my space.

Sounds like it!

what should the temp/humidity be at in your book?

With CO2, 85F, 90 max.

According to those much wiser than me, temps in the 90's are just fine if you are using co2. As far as humidity goes, one needs a dehumidifier in a sealed room.

If the heat produced by the dehumidifier (and they make a fair amount, they are little aircon units) doesn't tip the room over 85 avg 90 max, it'd be a solution for a ventless grow. I rely on my dehumidifier to warm up my op in winter during lights off as well as keep RH under control.

Walmart has a cute little a/c unit that sits entirely in the room with a small exhaust vent to outside for the excess heat. Naturally, with the cooling coils inside, it's a dehumidifier too.
