600 HPS Cool Tube Grow Light System

hm that curve is interesting, makes misting them seem pointless heh. i will definitely be getting a new hygrometer the one i have is beat to crap and probably off a little.
"Seems high temp alone may have been enough to control the RH." and it is a drrryyyy heat but maybe the fact that i liveo n a lake has something to do the humidity issues.

im gonna go look at these little dehumidifiers and wallmart a/c's today, ive got space in the closet above on a ledge i could stick them..

but theyd probably be more efficient at the bottom on the floor i would assume...guesss it depends on how big they are and loudness.

ug gotta go to wallmart....the HORROR

Good thread, guys. Good stuff for those looking to use cool tubes. In fact, I had a couple questions, and so far they have pretty much all been answered. I do have a couple things to ask/add about piping in a/c air thru your cool tubes...but unfortunately, I have not the time to type it all out right at the moment, so I'll have to come back later and add...when this thread reaches 15 pages. :eek: lol...


The Fog :rastasmoke:

haha please do tell before it gets to 15 pages, my sanity will be gone by then.

"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."

do you have a thread on this setup you had?

This thread is actually an insidious plot to see which goes first - your money or your sanity. There's actually a pool going on another thread. :S2:

Thanks for that, PC!

I think the problem had to do with me being a new user here. Yesterday, "Registered+" started appearing under my username and the "image" button now appears in my WYSIWYG editor.

I have gone around the board looking for user policies, but can't find out what the breakpoint is for giving a user img posting privs, whether that's post count or reputation points. Someone will know and chime in, I'm sure. :)

Would put it up high in the room (mine's within a foot of the ceiling)- warm air both rises and holds more water than cooler air... but enough circ fans in your room, the air will be pretty well homogenised and it won't really matter where it is.

The only downside to those portable aircon units is that even though they dump their heat via a roughly 4" vent duct (usually like dryer vent), that tube has to lead outside the op's airmass for the a/c unit to do anything at all. The upside is you get free distilled water for your plants. :)

I had already told you when you first posted that question in the Feedback/Suggestions section, Al B. I told you you'd have to have 50 posts. :) You now have that. Go back and read that post I made to ya, man. :)

Looking forward to the Cloning thread. Maybe it'll get Stickied.

Not on those ops. I was brought in as a consultant on those and they're not mine to photograph or talk too much about.

My own op doesn't have CO2 at the moment.

That you did. :) Thanks for that. :)

I can hear your mouse clicking...I see a cloning tutorial in our future. :)

When you consider that the surface temp of an HPS tube in free airspace is going to be at least 200C (~400F), I don't think it'll make much difference to the room air temp if you pipe ambient air at 30C (~80F) or air cooled by aircon at 10C (~50F) through the cooltubes.

Even if the ambient air you pump through the cooltubes is relatively warm compared to that cooled by an aircon unit, it's not going to pick up THAT much more heat if cooled first.

I'd reserve any feed from a ducted aircon system to be put on the plants instead of being used to cool the lights, bearing in mind that there has to be an air exit from the op or return path to the a/c unit if you pipe in cooled air from a central a/c system.

You make an excellent point, Al.

Al - If you go to the FAQ and look at the part on reputation it gives you a pretty good idea of how the whole points system works on this board.

I sent you some good rep to boost yer rating. Now that you have the + next to your registered, I think you're like a full-fledged member ...except there's no such thing as a member at c.com

... it's all quite confusing - obviously designed by a dro.

aaaaaaaaand now it's gone, no image button again. :mad:

Tried to do a post with manually inserted IMG tags and that won't work either.

Click the little paperclip in the upper tool bar and see if that's what you're looking for. You need to "go advanced" to get the right toolbars.

Could you kindly send a link? I have searched everything I could find called a FAQ:

Cannabis FAQs / FAQ , Recipes, Medical Marijuana
Cannabis FAQs / FAQ , Recipes, Medical Marijuana

...and don't turn up anything using the term "reputation."

I'm trying to create a new post, which starts in 'advanced' mode.

The paperclip button is for attachments. These appear at the end of the post in a clump.

I want to put images inline with the text, such as I have done in this post on GC.

A photoessay/tutorial makes more sense and is easier to read if the photos appear embedded with the text describing them instead of all the images appearing at the end of the post in a clump.

GC and cannabis.com forums as well as several others use the same forum software- I think it's vBulletin. Disallowing image posting inline is an admin setting- and it's shut off, at least for me, on cannabis.com.

Will do that, but was going to try to contact that user via a PM... and promptly found that there's no private msg facility available- at least to me. Am I missing something here?

Al - the rep thread is in this section. The thread itself is here.

BTW - The rules say 50 posts + 2 weeks membership to be able to post photos - but I think you can get approved quicker with rep points.

But - the Mods watch that section in the first link above and I bet if you posted a thread to the mods with a link to your cloning thread, they'd probably activate your photo privileges right away. The mods here seem pretty reasonable and pretty anxious to spread good info so, it's worth a shot.

Missing nothing - No PMs on this site.

I'm sure you're jesting a bit- I'm not terribly buried in victimhood, thanks.

However, it does seem timely to mention that this board's admin deleted my attempts to sign up 5 times before they finally approved it, but not before I sent several queries via the 'contact us' form asking why my signups were being deleted (and admin replied to none of those). Why? Beats the crap outta me, man. Maybe they didn't like my rather fuct username. :D

I've already sent a query last week via the 'contact us' form asking about this- and there has been no reply from admin. I just sent another query a few minutes ago, now that I have the 50 posts and the 'Registered+' thing happening.

I'll follow your suggestion anyway.

ok, the problem with imgs for me must be that I haven't been a user for 2 weeks yet. I'll try again later.

Al - of course I was 100% kidding about the victim thing.

Don't know what to tell ya about the other - this site doesn't seem real pc about usernames, so???

I never used the "contact us" form. I had a thread deleted and wondered why and I asked and Surrey's Princess posted a reply within about 30 minutes.

Yeah, I don't know what happened with the signup thing, nor am I all that stressed about it. I run a couple of non-dope related forums myself and I've inadvertently deleted real signups when weeding out the pharmaspammer signups, so anything could have happened.

thanks for the info on the dehumid/ac units...the ability to produce distilled water would be almost worth it on its own...

ima have to read up on this, as the tap water here isnt so great. prolly has a lot of prozac in it or something....i know for sure it has low magnezium and zinc. havnt called the water company yet to ask for their analysis...

hopefully if i can produce my own distilled i never will


on another note if anyone still cares BGH gave me a quote for a fully assembled, wired, and 5 year warranty'd cooltube/600W sunsystem10 for 380$, which is the same price from high tech garden supply for a 1000W/agrobrite ballast/cooltube setup with shipping.

but as you all have said the heat from a 1000 is a helluvalot more then a 600 so i think ive made my choice.

now to sell some kidneys!

wellllllll.... if you can cool a 600, chances are you can cool a 1000... and it's 90K lumens vs 160K lumens- and lumenz meanz budz (apologies to Heinz beans UK).

"wellllllll.... if you can cool a 600, chances are you can cool a 1000" would that really make a difference in a smaller space?

i thought the extra lumens would be wasted unless i was using at least 5x5x7 space...

maybe not?

Is your intended lighted floorspace 5x5 or 5x7?

Either way, the Rule-O'-Thumbâ?¢ for HPS in flowering is 50W/sq ft. If your plantspace is 5'x5', that's 25sf, which by the Rule-O'-Thumbâ?¢ would want 1250W of HPS.

no neither is, but it could be with enough pvc piping to create a room within a room....

well according to that rule o thumb trademarked madness i cannot handle such a large area anyway.

hadnt heard that before actually

But see, if you are using a verticle cooltube then all that square footage stuff goes out the window because you are bradcasting the light in a completely different way. You are using the entire bulb effectively, whereas in Al's computation you have to allow for the fact that half the light is going up and then being reflected back.

I dunno - but 1000watts sounds better than 600 to me.

Yep, 50W/sf is the generally accepted bell-curve centrepoint for HPS.

Tents of pandafilm within a room work great. They don't necessarily need verticals; a rectangle of 2x4 screwed to the ceiling or joists above, with a sheet of film over the top and the perimeter wrapped with film make a fine, reflective room-within-a-room. Nice technique for basements, attics, garages, etc.

Totally right, great point.

I'm also familiar with the 'stadium' or 'coliseum' type of vertical grow op you're describing, where the light is in the centre and the plants surround it. This lights the plants from one side as opposed to relatively evenly from above. I'm sure the plant phototropes to deal with one-side lighting- to some degree. There will always be 180 degrees of each bud in total shade.

However, at the end of the day, I think it's 6 o' one, half-dozen of the other. The more conventional method, with an efficient batwing reflector and flood trays (or other horizontal method) would yield relatively equivalently with less mechanical complexity.

Further to that, SoG exploits the normal growing habit of cannabis. The mainstem growing tips will always produce the biggest, most resinous buds. Side branches produce smaller, less dense buds, begging the question why one would side-light and encourage such growth.

The SoG technique uses a relatively large number of small plants grown for their mainstem tips only. Branching on the lower 1/3 of the plant is pruned off in wks 1 & 3. This forms a canopy of buds well suited to the max radiation pattern of horizontal-tube, batwing reflector type systems.

ah "less mechical complexity" those are soothing words.

since i do a scrog i guess i couldnt really do vertical then because i cant rotate the plants.

unless i could also wall mount plants too...which sounds like a fire heh


pandafilm looks very useful but every only seems to sell it in rolls of 100 feet for 90$.

weird there arnt half orders anywhere

Looking at this typing, I'm wondering if you've been out selling blood this morning. When you do that, you probably should limit it to 3-4 pints per day. LOL

Hey, Al. B Fuct. I read a couple of your posts... and you know too much. Youre now my idol. :D

Some hydro shops will sell you cut pieces of pandafilm but they usually jack the hell out of the price for small lots. It's great stuff, well worth buying, but I agree, a whole roll is a lot. I didn't even use a whole roll when I recently rebuilt my op. Still coming up with inventive new uses for leftover pandafilm. Makes great weedmat for my flower beds. :D
