What do you think my chances are?

That is the reason I wish growers were just required to have electricians come certify their rooms!

As far as the fan I might have an idea for you. If heat becomes an issue for you then pushing or pulling air from outside the tent through the light then outside the tent again will help combat that for you. That really will be controlled by what wattage bulb you use and how much heat it is generating.

Lucky I have a NZ electrical licence........have not worked in that industry for years.

My fan will be bringing fresh air from outside, dumping outside during warmer days, then switch to your suggestion during colder months to dump the warmer vented air into the mass of the room to stabilize that a little from cooling.




So - mucking around in the shed for the last hour - and this is what I have came up with -

IMG_0385.jpg IMG_0389.jpg IMG_0390.jpg Nicely calibrated too.


One to control mother room, 1 for the clone and the last goes to the flowering room. wired with 1.5mm, short distance - easily capable of carrying easy 20amps on 240v, no worries on heating mode being series wired .

how about a twin speed fan with a room thermostat on?... that what i use and i swear by it

The twin speed motor, you still have to wire this manually for control?

Room thermostat is basically what I am using, but its digital. I am thinking using speed control I will have more 'finer' control during warmer and cooler months and even warmer and cooler days.

Wired up the three tent rooms today.

IMG_0393.jpg IMG_0392.jpg Excuse the birds nest for wiring at the moment.


Top temp is the flowering room, which controls the bottom right fan speed control (not finished wiring like the left at the moment). This temp is taken 450mm (18") below the son-t. No exhaust for filter running yet, waiting for the variac to turn up to run the fan with.

Middle is the clone room which controls the bottom left speed control for the fan.

Bottom is the mother room. This is holding temp o.k for some silly reason without a fan or venting at the moment.

Heat rises? lol

Can't think of any other reason why the lower chamber would be cooler without fans. Is the tent sitting on concrete?

I've got the Canna Nutrients too and I'm happy with them. I've been switching back and forth between Canna Nutrients and the full Fox farm line on each grow and as of right now, I'm in the Canna Nutrients camp. I only use the Canna grow and bloom though and supplement it with the Fox Farms Open Sesame, Beastie Bloomz, and Cha Ching. I think once my Fox farm shit is used up I'll probably go 100% Canna Nutrients. I like it better and it's cheaper.

Sealed unit between clone and mother, and for this fact, one would think having a 150w heater inside it would heat up. Heat does rise, but has no where to go, other than transfer through the roof to the cooler clone side (heat goes where it is colder). Starting to think the fan above is scrubbing the heat away from the roof to the mother room ??

Yip sitting on concrete, and coming into autumn - maybe I need to put the tents on thick polystyrene or something,.......think about that later.

IMG_0401.jpg IMG_0396.jpg Closed air circuit for the hood - 150mm axial fan pushing over son-t and out. Fan is inside the tent, directly attached to the

tent, and directly sucks from outside the tent. IMG_0398.jpg - but can anyone spot my mistake ??


By having the fan directly attached as shown, the light is off centre from the tent - buggar! Add some ducting later today.

As always - your input or knowledge will be gratefully accepted

What I do need to know is:

What size water pump to elevate water 0.750mm up and then fill the flood tray. Don't forget the flood tray is filled from the bottom, so the pump has to contend with the pressure from a full flood tray also.

Any one got any ideas?

This is where my mother's will come from, IMG_0403.jpg Two of the 3 pots will become my mothers when I transplant to a bit bigger pot.

The big pot will be going in the flowering tent to have a taste of when it is running correctly. Thinking by the time I have clones in the flowering tent running hydro, the outside sunlight will be well into 12/ 12 conditions, and then I will put back outside to finish off when I introduce the first set of clones for hydro ???




Can't wait till April to harvest this IMG_0402.jpg All I know about what is shown is the strain Indica.

Dude i think its really dope how you made your own ballast. How did you do that? Im sure the DIY section would definitely appreciate a tutorial on that ;)
Good luck with your plans

Thanks - I can read wiring diagrams a little - and if you can read this mess IMG_0405.jpg you can to. I chuck this together late last night, its the running gear for the 400w. Incoming phase and one side of cap into the ballast, out of the ballast into the ignitor, from the ignitor to the lamp - put all neutrals and the remaining cap wire into the neutral on ignitor - turn on and watch the glow.

IMG_0406.jpg You can see the 150w at the back and the 400w front.

The problem is that heat in everyday language is not the same when talking about thermodynamics or the physical concept of heat.

My answer anyways.

It's kind of a trick question.
The first time I heard it I "Knew" heat went up ~ I was wrong.

Heat moves in three ways: Radiation, conduction, and convection, but none of them exclusively in the "up" direction.

Hot air does tho. :cool:

So is that sticker at the top right hand corner the diagram your talking about? or you just mean the picture in general - read as a diagram?

You are right on both occasions. There is a diagram on the igintor also, the cap (capacitor) is the round looking thing.

Woop woop - my variac has turned up

IMG_0431.jpg IMG_0432.jpg Plugged the fan into the variac - it's not until about 180v's (240v circuit) I can start hearing the air come out, and this is without

ducting on - think I have cracked the stealth fan set up....!

80 - 100volts it's sucking a fair amount of air m3 and its silent....!

No doubt thats alot of voltage for a fan! shieeet :P
Thanks for your reply too. Gonna try and figure it out and maybe sketch my own out.
