I am running 3 hlg 650Rs (diablos) in a 10’x 20’ room. I only have my lights at about 1/2 strength. I am running co2 at 1500ppm. The ceilings are only 7.5’ tall. Most of my plants are hooked up to an auto pot watering system. My high temp is running at 82 degrees. I am running Subcools super soil. What can i do to make this room produce more? I would like at least 1# or more per light.
One of the many things you can do as a homeowner to keep your house free of those pests is…
Shiiiiiiit, I grow no-till in my basement and I literally water with my garden hose. Ph out of the tap…
bugs?
here is the timestamp for the bleach procedure https://www.youtube.com/watch?v=9JT2RjIkfGQ&t=2250s
@Cos_genx the only readily available (to average consumers) is a soak in a 20%+bleach solution. This will obviously kill seeds…

I would up the light power if you can with them half power that high above the canopy your probably at 300-400 ppfd which is not conducive for mass flower production. If you can’t add more heat to your room i.e. no AC I would lower the lights for sure so that you’re within a 4×4-5×5 foot print, get a par meter and get your plants up to 800-1000 ppfd.
Thank u soooo much. This is the kind of answer i was looking for. I wish i had the money for a Pulse Pro.If i had one of those i could get this dialed in. Some of my concern though is previously when i had the lights turned all the way up not all the plants liked it. Maybe i will start by turning up the lights a little bit till i get to 80% ish and see how the plants respond. Thank u TJ Dirtsniiffer and Thank u DGC
Do you think it would work better if your plants were at the same height? They definitely seem quite different from each other. Are the ones that get angry about the light,ones that are tall?
Pack that room walll to wall with plants. Then you will truly be able to see your ppfd as the plants grow. I would also stick too just one of two strains. Running nutrients is easier. Looks like your room could use some fans. The breeze makes the plants stronger. The one with the bamboo looks alittle over trimmed.
The style you’re growing in there is what I call “JBOP”: Just a Bunch Of Plants.
You could EASILY double to triple your yield just scrogging. Horizontal trellis, running lengthwise and the width of your desired canopy. For that room, I’d say maybe 30″ off the floor.
Veg your plants under the scrog, and as your plants grow into and through the mesh net, bend them down so they’re “horizontal” under the mesh. Accounting for flowering stretch, when you predict they’d be filled in in 2 weeks is when you flip to flower. The plants will do their 2 week stretch into the mesh and you’re doing your bending and tucking.
The resulting plants will “fill out” that whole grid and yield 2x-3x in the same space without costing you a dime more in electricity.
There are many ways to DIY a scrog; the basics are it’s a 3″-ish grid. I constructed my 3×6 scrog out of 1″ PVC pipe, some 1/2″ sheet metal screws and a spool of cotton twine. Maybe $25 total for the whole project and I’ve used it through the past 5 harvests without even changing the string.
On a scrog, and with me really still being a beginner (10 harvests now) I typically get around 1oz (cured) per sqft. I got just over a pound out of my last 3×5 canopy and that was under-lit at the edges.
With a scrog, and, say a 5×16 canopy footprint (in your 10×20 room), I would expect once you got the scrog technique down you should be able to pull 4-5 pounds (at least, maybe 6-7 once you get good at it and with the right strains) if you harvested the whole room at once.
Right now, you’re under-lit at the outer edges lengthwise–those lights can’t flower a 7′ edge, so you’re likely to be better off with a narrower canopy, maybe 5′ wide.
Obviously, there’s a bit more work to it if you’re growing 8 strains all at once. But you can always time things to veg them all to roughly the same size, and THEN flip, and you’ll have your whole room in sync in the net. You can still stagger your grows if needed, but it can get more difficult with a scrog getting in there to remove just one plant from the middle.
Also, in every bit of research I’ve been able to come up with, CO2 PPMs and PPFD should roughly match give or take. If you’re only getting 300PPFD (at that height) your plants aren’t likely using more than 300-400 PPM CO2, so at 1000PPM you’re just wasting it. Once you drop your lights to the correct height, you should be up there in the 1000 PPFD range, and THEN your plants will consume more CO2 up to around 1000PPM.
From my own experience I’ve found when you up the lights and CO2, you also up the water and nutrient demands (faster and more photosynthesis requires commensurate input adjustments).
