i have the same along with as much HARD STRAIGHT pipe as possble for my tubes and the air coming out when 2 600s and 1 1000 are on is 31.7'C. the duct and cooltube themselves do not get that hot. i can touch my cooltube with the 1000 heated up and its just maybe above warm to the touch(almost hotter 6"away) and the duct doesnt even get warm.
Yep, that's the way to do it. The PVC pipe or proper galvanised steel air ducting will have much less flow resistance than any sort of flexible duct. Downside is it's BLOODY expensive. 150mm dia might be hard to get at some local hdwe shops, but it's around, certainly at megahdwe shops and trade supply houses.

It's worth noting that plastic flexiduct is the most flow resistant, particularly if it its not pulled out taut.

i think al has a pik of himself touching his hot cooltubed 1000 chek it
yep, this one is from pre-installation tests on the garage floor, before I had cut out the cooltubes' in-built reflectors.



If your ducting system has insufficient flow, due either to a wimpy blower or too long a duct for the sort of fan used (use a centrif instead of an axial blower for lengths much more than about 6-7m or with several 90 bends), the cooltube will become warm to the touch.

If the glass is allowed to get warm, heat will transfer by convection into the growroom air, defeating the purpose.

hell ya im going to get a centrifig fan in a couple days.. is this one u think good or recommend a better one?? and this is pretty much what my set up is gonna look like except with out those bootleg milk cartons haha

Best centrif blower I know of is the 250mm Spectrum Customline C250L. Dead quiet yet shifts 280L/sec (bout 600CFM) with a 250W motor. Good value for money, about AUD$211. This is the low flow, low noise version of the 480W monster C250H which moves a wind-tunnel-like 420L/sec (890CFM).

I think you're going to want to reconsider your arrangement. You'll want a separate cooltube blower and room air exhaust fan, as such:



If you use the main exhaust to run the cooltube, it cannot be run on a thermostat. Cooltubes require constant airflow during lights on plus about 15 mins after lights-off to cool down the lamps and sockets. The cooltube fan will need its own timer, synced to lights-on times, plus 15 mins.

If your main exhaust is used to run the cooltube and thus has to run constantly, you have no control over room air temp. Room airmass will be whatever the intake air temp is, plus a couple degrees C.

also i wanna see some pics of some gooood chronic you have, if u have any pics haha heres some i harvested 3 weeks ago or so.
How about a pic of your ordinary, average SoG budstalk being manicured? :)



About an oz on the hoof, as it were. ;)

You don't think R/O is really important? Should I just use my cities water with the ph adjusted?
You bet. Drinking water from modern municipal reticulation systems is just fine for growing plants.

Chlorination and fluoridation as added to municipal water supplies will not harm plants. Chlorination in fact is the indoor grower's friend. It will suppress pathogens while the water is in the pipes coming to you and will also suppress them in your tanks for a day or two until the chlorine evaporates. After that, unless you add a pathogen suppressor like H2O2, you have a nice big tank of yummy nutrient soup that all plants, including fungi & algae, will happily eat- or live in.

Some have argued that chlorination kills beneficial bacteria in soils. That may well be possible to some degree, but a) there's ideally no bacteria at all in a recirculating hydro op and b) my all organic veg patch out the back yielded a double trunked, 12ft tall cherry tomato plant which produced over 450 fruit this last season, mainly on chlorinated tapwater from the garden hose.


(yep, it's ONE plant...)

If it's safe to drink, it will grow fine plants.

you ever plan on changing from the st#4? don't you like a little variety for your personal smoke?

thats a pretty spear you got on that bucket there!

I used to run a number of different strains, but I pared it down to the best compromise of buzz, flavour & total weight production. ST4 just kicks the ass off everything in every way except for the production from clearly mutant monster strains like LUI & Skunk #1. ST4 makes about 85-90% of those characters' yields, though.

I have never gotten tired of ST4, but I think I would like another copy of White Widow just cos it's tasty as fuck. Might like to play with some citrusy sativas to have a lighter headbuzz sort for some occasions.

In general though, my op is streamlined for production. Multiple strains, while fun, cause problems in the production line system, especially with plants that develop different statures. I have space only for 10 mums and I'd never want to keep less than 2 of a strain going at any given time. If I add a strain, that leaves 8 spots for ST4. I can run my 30 cuts every 2 wks on 6 plants, but must always have 6 ready to cut. 2 spots are for replacement mums that are vegging up from clones. I could add 1 strain and not hurt my rotation process.

innit. :)

That's the usual when things are going well.

I just wanted to take a second and tell you I am a big fan of all your work and I appreciate all the time you spend sharing your knowledge. Your wisdom has givin me a whole other way of seeing the way I ran things and to be honest has made my life a whole lot easier in many ways, thanks again..

let me know...
i'm quite the fan of sativa's, and have a few nice crosses... if you still have my email you know where you can catch me at...


i was looking at some pictures of some ST3 done on another forum, and i was suprised to see how different the buds looked than yours... different ops and all, but i would have thought that the breeders line would have been a bit more similar between versions...

maybe i'll have to look into what the differences breeding wise are and i'll prolly find my answer...

The only info I have about ST3 is that it had a mould resistance problem.

If you have a link to that ST3 grow, I'd like a peek. :)

Could we see some close ups of your bud ready to smoke?
OK :)



close enough? :)

al b fuct you are the greatest! I just bought 2 darkrooms one is 7'10x7'10 for flowering and one thats 2'5x2'5 for the mother plants.

I want to do your grow setup as close as possible
What do you suggest i put in them? Or if you can draw a small picture on how i should set it up. I just have no idea this is my first grow.
THANK YOU

Sorry I dont think i was specific enough, I was wondering what size Fan you think I should use and what size filter and how i should ventalate the hut. Thank you

That's some beautiful bud. I bet it smokes as good as it looks. :joint:
Thanks. As you might expect, ST4 has a sweet, perfumey flavour. Very smooth when you have got the moisture content right, a real joy in a big fat jay. My circle has been smoking it for the last 6 years and all still love it. Can't grow enough of ST4, ppl always come back for more. A real success for a production grow and a damn nice smoke, too. Hard to get as beans these days, I hear. I sprouted these in 2002 and have been propagating by cuttings since.

Thanks, ftg. Hang around here, catch up reading this thread in its entirety if you can, we'll bust ya cherry. ;)

Start small, but not so small you smoke your entire production in a week. SoG relies on a large number of small plants, plan on 1/4-1/2oz per budstalk in the beginning of a grower's learning curve. For a first op, you might do a single 900mm x 900mm (3'x3') flood tray & a 400HPS for flowering, perhaps a 300mm x 1500mm (1'x3.5)' tray with a 175MH or 250 HPS for mums.

Ventilation is job 1. Pick a space that can easily be ventilated, either by dumping your waste air into an attic, crawlspace, or less desirably, out a window. Exhaust air must not be easily drawn back into the op.

Cooltubes are a great investment but between duct, blower, reflector and cooltube, isn't hard to wrap up a cpl $100 in them. Cooltubes vastly improved temp stability in my op. Stays at 25C +/- 1C at all times now. If you have the dough, get 'em now. If not, plan the op to suit cooltubes and duct installation later on.

You also need a clonebox, Enigma modded up an old bookcase with some pandafilm, fluoro lighting and presumably a thermostatically controlled exhaust fan & heatmat as a clonebox. Sounds a beaut.

Let me know when you have all that done, k? :)

Sorry I dont think i was specific enough, I was wondering what size Fan you think I should use and what size filter and how i should ventalate the hut. Thank you
Your room exhaust blower in a cooltubed room should be able to shift the room's air volume in about 3 minutes. A 500cu ft room thus needs a roughly 170CFM fan (500cu ft / 3minutes = 166.67CFM),or more. You can use passive intake, with no intake blower, or you can use an axial blower rated about 80-90% of the exhaust blower's CFM rating.This keeps the room at slightly negative pressure, sucks air into the room via small gaps in construction instead of allowing scents to escape, were the intake blower bigger than the exhaust.

The cooltube will use a typical 150mm axial (most are about 200CFM) if your duct is under about 6-7m long and has only a couple of 90 bends. Long, sweeping bends are better than sharp ones in duct lines.

If you're going to use a carbon filter, you will need to use a centrifugal blower for the exhaust. Axials won't do the job pushing air into a high static pressure caused by the obstruction of the carbon filter. Match the filter to the flow rate of the blower.

Should be arranged a bit like this:

What a thread!

Al, my question is, if you were to grow sativas, how would you go about it? I know SOG favors indica dominant plants, but i was wondering, what method you would employ if you "had" to grow a sativa.

I will be emulating your setup for my indica plants, blueberry, mazar and granddady purple.

But i have a OG Kush/S.A.G.E mother that i would love to grow.

Any info is greatly appreciated.

hey al I have just got the op running to exact scale of yours I can't thank you enough for the tutilage i have recieved, My clones are growing into mums so i can take the large amount of cuttings off of them , how do you get the moms ready for the large cuttings you take off of them do you prune top ect. I have read this post a couple of times and I apologize if this question slipped by me thanks seeker
