3rd Grow - Time For The Light Show

[Weaselcracker]

Celt's suggestion could definitely work. Good idea

 

[B A R]

Well this might be a suggestion for you mate. Make your tent a "down draft" like a paint booth for painting autos. If both vents are the same size and you have room to move the exhaust fan assembly to floor level, exhaust out the bottom of the tent to your chimney and bring your intake in the top from your wall vent.

I don't know about that Celt. I may have been the kid in the back of the class snapping jokes during Physical Science but do remember that heat rises and that's the biggest thing most of us try to rid our tents of.

Too funny Weaselcracker

I will visit your journal, didn't even know you had one LOL

Likewise.

 

[Robert Celt]

You are right BAR, heat does rise in a room. That's why heaters are usually at floor level. But that's in a passive heating situation where there natural tendency of heat to rise mixes the air in a room, not the most efficient way to heat a room. If you where to take 3 thermometers and place them at floor, mid-height and ceiling, you would find 3 different temps.

There are many situations where heat is applied at the upper part of the room and forced down. Most commercial buildings and mini-split heat pumps are cases of this and they actually heat the air in the room better giving a more even heat throughout the room.

This my not be feasible for Kraize's tent because he may not have the room to put his extractor fan assembly at floor level. The reason I suggested this route was to minimize bends in his ducting. A lot of bends in the ducting would do more to impede airflow than reversing the natural flow of heat.

 

[Kriaze]

Hey TheCelt thanks for the suggestion. I wouldn't have the room for the extractor fan at the bottom of the tent unless it was outside. Maybe if I ran the ducting through tent it would work but I wouldn't be able to use the carbon scrubber so that would be a no no situation. I was thinking along the same lines as B A R in that heat rises so I need to exhaust from the top, I'm kind of tempted to try your idea to see how well it would work but realistically there's no way I can use the exhaust fan and scrubber lower down.

Weaselcracker is probably right about my fan not moving enough air to push it down 15ft of ducting so I may look at a booster fan which I could place on the floor near the chimney vent to help pull the hot air through. I should think two fans could manage it, it's something I'll have to think on. At least the temps are ok when the window to the room is open, but it crept up to 30C yesterday which is what caused me to rethink my cooling solution.

Thanks for the input everyone it's greatly appreciated. I'm going to scratch my head for awhile on this until a solution appears. I hope you are all well, all the best

No worries mate, we are all here to help and learn from one another.

No doubt Celt.
Like I said, I was in the back of the class but I don't use scrubbers or anything, just intake and exhaust and it only makes sense to me to have the exhaust directly under the source of the heat; my LED lamps. I can actually feel the heat outside the tent on my hand when I place it over the exhaust holes.
It's brought my temps down in all 3 of our tents plus the AC in my bedroom keeps the floor the coolest so the intakes are at the bottom. Hard to convince me otherwise when it's working but I've been known to be stubborn and hard-headed.

 

[Robert Celt]

That's funny BAR I was a class clown too LOL but for me the math and physics came natural to me so didn't have to do much work to understand, which is a GOOD thing as I was always a lazy student LOL being lazy, things like biology, English, history etc were my down fall LOL

Even my grow room is like yours with cold in the bottom and hot out the top. My room is in a basement so I used the natural flow of hot/cold air to my advantage

 

[B A R]

I've been known to be stubborn and hard-headed.

Just like Mr. Evans, my 9th grade Science teacher couldn't convince me hot water in ice trays would freeze on the top surface before ice trays with room temperature water would in the freezer until he proved his point and made me look stupid. To this very day I fill my ice trays with hot water. LOL

EDIT: Which is why I still remember his name.

 

[Robert Celt]

LOL too funny

 

[Kriaze]

There may be trouble ahead.

I decided I would feed the plants today and was intending on doing a low ratio portion of Canna Vega. A little bit of a distraction occurred and after I'd fed them I could kick myself. I realised that I'd used a full ratio of feed (5ml per litre) and also a full strength dose of Rhizotonic @5ml per litre. It's too late now so I'm going to keep my fingers crossed that they'll handle it, but I get the feeling I'll be flushing them out soon enough. Only time will tell. Wishing you all the best

Interesting fact regarding the hot water freezing quicker than cold B A R. I've got to give that one a try later

 

[B A R]

Sorry about your mishaps but mistakes do happen. About the ice, I'm not sure if the whole cubes finish quicker but the surface does. It has something to do with the steam from the hot water if my memory serves me correct.

 

[Kriaze]

Definitely very strange but intriguing. I'll be testing this theory later on with my son, thanks for sharing

As a backup plan I've just gone and dug four more pots out of the shed, seems a shame to see one of these tents empty and the CFL unused

 

[Kriaze]

So I went ahead and did it. I've set another 4 seeds going using the paper towel method which I will veg under the CFL in the other tent.

These seeds were:

1x Bubblegum XL
1x Big Freeze
1x Amnesia VIP
1x White Widow

It's just a case of keeping the towel moist and my fingers crossed for now. All the best

 

[arellanobrian]

hope all the new seeds germ!!

 

[Kriaze]

Cheers arellanobrian. They should be fine, I'm more confident with the germination procedure than I am at growing the full plants for sure

I hope all is well over the pond, all the best

 

[db003]

I felt the same way about having a empty tent that's why I got some autos to grow in the veg tent while my other tent is in flower good luck with the new seeds

 

[Kriaze]

Thanks db003. I'm happy to hear you fixed your temps too, it's even a bane for me in the UK with all the hot weather we're having lately. All the best

 

[uhewekguilw]

Good luck on the new seeds Kriaze! I'm sending you some good karma from over here!
Keep at it bro!

 

[Kriaze]

Hey GB thanks for the good wishes, I'll be going looking at the seeds very shortly so I will update if there's any change. Sending some good karma over to your side of the pond too, although after seeing your bud yesterday you have floods of it already All the best mate

 

[Amadeus Forzin]

Lookin well in here
