Next I built a sheet metal tray to sit on the dolly. The lip is 5/8" high all around and I cut out a notch at the low point for the water to drain out.
The notch also lets the tray bend to the shape of the plywood underneath. And now the 2" hole in the plywood probably makes more sense.
Having two unequal lights, I needed a way to shift a crop from the 400 side to the 600 side each month. I grow under a screen so that complicates things, I dont want to be pulling the screen off 1 month into flowering. So for the past month ive been thinking about ways to build a mobile scrog...
The water has been in there 5 days. Temps are from low 70's to low 90's. Ph is the high 5's.
The walls, air tube, and the foam rubber plugs to hold the clones all felt slimy. Its a 1 gal tupperware bin completely covered in black duct tape.
Is this algae starting?
Should I add another...
Air cooled lights are one of the best things that ever happened to us.
Thanks.
I have 2 different reflectors, and the one on the right is much less restrictive to air flow. The intake side of the light is cool and the exhaust duct is real hot. I have confidence in it, for now lol.
I went a...
Building the intake ports for the box.
The light traps will be dryer hoses coiled vertically and mounted to the inside of the front wall. I used 4" ducts instead of 6" for this because we all know how good an extra 2" can be when the room is packed.
A 6" hose has an area of roughly 28...
Lights hooked up. 400 on the left, 600 on the right. The ballast for the 400 is already in my attic where i dont care about heat. I'll be running the wires to move the 600's ballast in there today.
Ducting finished, until i decide i need one of those little air conditioners.
Today Im...
For the door I used hardwood plywood. Its a little more resistant to warping. Heres my friend in the process of screwing down the top after all the holes were cut and the underside was painted white.
The duct in the back is suction to cool the lights, the one in the middle is the vent for...
My previous flower box was an 18"x34" scrog box with an air cooled 400 hps.
Im taking over the rest of the closet now, which gives me 48"x60", and adding another light, a 600 hps. That air duct hanging there goes into my attic. At the other end are 2 inline fans that suck 24/7 and a...
Well, I use a scrog setup, so i dont really have any lower bud sites. Where can I find more info about a flip flop switch? Id love to run 2 bulbs off one ballast, I didnt know that was doable.
I have 2 hps lights in my flowering room, 400 and a 600, both hps. I will have 2 flowering crops, a month apart, at any given time. Which crop should I have under the 600, the ones in the first month of flowering or the ones in the second month?
I start a new crop every 2-3 months. Today I open up my soil mixing bin after its been sitting in my cold garage for 3 months, and I find mold. I left a cup in there for scooping out soil, and the cup is covered with mold. I dont see any mold on the soil or on the sides of the bin, just on...
I would throw it out.

Get a pack of the 5600K's or even 5600K's if thats all you can find. They'll make it grow short and bushy. 2700's make them grow tall and thin.
I grow the main stem horizontally in one direction, and i'll grow the next biggest branch horizontally in the opposite direction. Theyre growing an inch a day and will be getting real bushy in the next week or 5.
