My New Room

[puff adder]

Here's some pics of my new room.

One pic is my pots, locked and loaded, ready for potting up.

4'x12' trays I made from ply and fence slat borders and black tarp for under $100

If you look, you can see the 8" fan that draws air from under the house and into the room. It cranks out cold air and causes a positive pressure in the room.

I built a big filter box from one of my hood boxes, that went under the house, so all air entering the room is filtered.

The positive pressure in the room pushes the air across the lights and outside without using a fan. Tests on a cool day temps were under 80 using just the one 8" fan to cool the 6K room. The lights will run during the night in flower.

Presently I'm vegging with 2 lights.

This year is a tough year, different from other years in that the disease pressure is so high. EVERYONE I know has powdery mildew, including myself for the first time. My young starts in this new room got root aphids.
I have always maintained a good environment in my other room, and I think that has gotten me by to this point without bugs or PM.
I am spraying more now than ever before.

After this first run is done, I think I am going to go sealed room with AC, line the entire room with poly, do it 100% right.

I'm planning on 9 plants per light. They're in 2 gallon pots of Canna coco, and I may pot up into bigger pots. The room has lower ceilings so I can't grow tall plants.
I plan to use a trellace, and to flip these girls after all the holes are filled.

Wish me Luck!

Oh Yeah, strain is Grandaddy Purple.

Hopefully these pics will work

Nice clean set up look forward to following this

dope setup bro!

Thanks very much!

The room is 13'x15'.

I have the ballasts and resevoirs (I have two 40 gallon resevoirs) located in the bathroom (which also sits a foot or so lower than the room), the wires go through the wall.

The 4'x12' trays I installed drains, which will have 1/2" hose going down into the bathroom, and into tubs or buckets. The trays are shimmed to drain at the corner of the drain.

I plan to use a drip system, so I can water to runoff. I tried dialing in drip in my other room (no runoff-catch trays) and the only way I can see drip working is with drainage/runoff or recirculating.

I will probably hand water in veg, and build the drip system for flowering.

My grows in my other room have been no runoff pretty much, and I'm hoping to improve things with being able to evenly soak every plant to runoff at least occasionally. This also allows me to officially "flush" if I need/choose.

I will be using a trellace, and possibly some reflective material around the trays.

The plants are all potted up, I'll post more pics tomorrow.

Nice room.

Here's some more pics. Plants are cranking along nicely.

I'll be doing 9 plants per light, vegging under two 1K's right now.

I will be doing 5 lights worth of Grandaddy Purple, and I'm doing one 1K worth of a new strain called Acme 12.

The potting up was seamless, plants are cranking right along.

No signs of bugs. I discovered root aphids when I potted up. I applied the appropriate pesticide. I'll give one more application next week and that should be the end of the root aphids for good.

Lookin' good.

Just a suggestion... you might have better luck with the yellow sticky traps lower closer to the plants.

 

[puff adder]

I've got them down in the corners of the trays, and above, and along the ceiling. Yellow and blue stickie traps everywhere! The ones on the ceiling seem to catch the most in my other room.
Mosquito dunks have permanent residence in my resevoirs.

It's been a while, time for an update.

I've been vegging under 3 lights, and I flipped to 12-12 yesterday.

The positive pressure and thermostat have kept temps at 75 degrees, with the fan cycling on and off.

Last night was the first full 12 hours with all 6 lights turned on. I was very happy to open the door to the room and find the temps at around 76-78.

The bathroom, where my ballasts are mounted was a bit hot however. There's an open window, but without any air movement and no exhausting air it was probably 90 or better. Today I'm picking up some fans, and I'll figure out how to exchange the air in there.
There;s a 4" dryer duct in the floor, I'm looking at possibly using it to draw cold air from under the house, maybe duct the air directly At the ballasts, with another fan in the window to yank out the hot air.

The plants look great, and it looks like my single-fan positive pressure room is capable of staying cool. Things are looking good!

I'll post some pics very soon.

fuck yeah, that's a nice looking room ya got in the making there man.

getting my ass parked for the show.

the one thing i would do, is cover the floor with some pond tarp, it's also handy to cover the walls in the white plastic. the floor in case of spills and splashes and the wall, for when you need to spray the plants, maybe if they get pests (touch wood). so you don't end up causing more damage then needed.

love your air cooled lights.

Thanks for the tips!

Plan A was to put up white poly plastic everywhere, but the house is already trashed, not worried about damage at all.
The trays are lined and have drain holes so I can water to runoff or flush if I desire. I plan to make a drip system, which makes life much easier.
My other room is a carpeted bedroom that I've managed to run for 2 years without spilling and no damage, I've gotten pretty good at keeping the spills and sloshing down. I have a drip system working very well in this room.

In the new room I added a fan that blows directly onto the ballasts, and another fan that draws air out the window, causing a negative pressure in the bathroom. This negative pressure sucks cold air from under the house through the 4" dryer duct in the floor.
I'm hoping this drops the temps acceptably, otherwise I will need to put my resevoirs, and nutes in another room. Grow room temps are good.
I'm going tonight when the lights turn on, and I'll take some pics. It looks really good.

looks like yea got it dialed in quite nicely,,

cant wait for pics

 

[puff adder]

Here's some pics.

The fans worked a charm in the bath/ballast room, it was actually Cold in there! Grow room temps are right at 78, I may add helper fans to the lights but another expensive fan is not necessary.

Nutes are GH 0-6-9, 3ml/gal Botanicare Cal-Mag and Pro-Tekt Silica.
For Veg I'm also using the GO roots (1/2 strength) and Diamond Nectar (1/2 strength). Every other watering I add some Florolicious Plus. PPM's are around 950-1000 with 140ppm well water.

looks great man!

Keep up the good work and best of luck

wow mate looking nice! very clean!

 

[puff adder]

Thanks very much!

Over the last few years I have learned very much from those on this forum, which has been invaluable to me.

Just an update. I'll take pics and post tomorrow.

I am so stoked that my room design works flawlessly. I am cooling a 13'x15' room with six 1000 watt lights with One 8" valueline 747cfm fan and 2 8" helper fans, that's it!

It got into the 90's last week. Lights are on at night, and when I entered the room just before lights-out, the temps were 77 and humidity 50%.
Plants are on day 15 and cranking.

Utilizing the cold air from under the house is working very well for me.

Someday, somewhere else, I want to up my game and build a sealed room and run C02.
