12 Plants Under ~600w Cob Leds

Getting some def, going there tomorrow to swap the water out for new nutes, adding a little more calmag and epsom salts

they getting bushy now

i have about 650w of led power, 12 plants, lights should produce around 1g/w. Do you think these clones are big enough to yeild 50g each if i flower them now? will scroging this definitely up my yeild?

I use RO for my organic soil. My well water was killing my canna, but not my veggies, weird! It was definitely the water too.
my ppms weren't high either, around 125 average. Even had the water tested nothing showed that should have done that.Bought a cheap RO filter system and no more problems at all. I add 90-120 ppms of cal/mag to all the water I make, never a cal/mag issue

And yes, reverse osmosis water in Hydro is as absolute must. People who say "oh I use tap water with great results" have never tried r/o water and have no idea what they're missing out on.

or throwing the shitty airstones in the trash, or maybe both and start fresh.

And If your nutes are DISSOLVING air stones, I would highly suggest throwing them directly in the trash and use GH Flora TrIo. Imagine what it does to those precious, fragile root hairs.

I'm with sixstring on the extra week, they look good, an extra week they should be a fair bit bigger in your system.
Not sure about the scrog idea though, a true scrog should of been done a few weeks ago so you could train them into the net. By the look of them at the moment it wouldn't be a true scrog, although the net or trellis would help support them.
To get them in a proper scrog now they would have to be bent doubled over and then the side branches trained and spread to fill the net so when you flip all you have is colas above and nothing but branch below the net.

Put the screen up, had to split it up. 4 plants 3 x 3 foot scrog 200w.



Another with 8 plants 6 x 3 foot scrog. 400w


Im going to veg for another 7 days then flip. Or should i rather let them fill the screen then flip? First time scroging hope this helps!

is that enough light for that big rooms? Maybe youre still in time to add a few more cobs ! Looks great though, cant wait to see them flowering.

That I can't tell you. Like i said, i have around 600w of light and they should yeild 1g/w and the plants are still small, don't think they will yeild more than 30g atm. So I'm going to veg for another week, or till the screen is filled about 60% then flip it to flower.

Is that plant under a urinal?

I am curious to see how this turns out especially in that 6x3 area.

Yes, its a outside bathroom, if you look closely, on the other one there is a whole toilet, the last plant right at the back is on top of the toilet, you can see the bowl right in the back.

Its the only space I had available that nosy people wont look in. I wanted to smash the urinal but the girlfriend had some objections

What K are you using? 2700 or 3000?

i used 4000k

Ok. They looked yellower. I am interested because I am going to be running 6 plants under 16 cobs 4ea pushed by hlg185-1400. 12 are 3500 and 4 are 4000 in a 3x6 area.

How far is the light above the plants?

I'd be afraid that the urinal will block some much needed light in that corner and maybe create a shadow or dark spot
