That looks like a great setup Medi. How tall will you let them grow?

yes its a 55gal rez and a 7 gal controller bucket with digital timer for fill and drain the buckets are 5gal and I set the 5gal euivelant air pots inside full of super course pearlite

just long enough to fill the screen %90 ....average 3 to 4 weeks depending on strain

Thanks. Do you throw them into 12/12 before the screen fills to 90%?

can anyone tell me how far should the light be from the net? (vented hood) 600whps. I need to set the net pre flip and the light is as high as it can go. thanks in advance.

8-12 inches would be my best guess, put your hand at plant height when the light is on if it's too hot for the back of your hand it's too hot for the plants. Get air moving over the top of the canopy as well and it will help greatly, if you don't have it already. I put my 400watt about 8-12 inches and point a fan directly at the glass.

she's a bit shy lightwise and will bleach if I let her get anywhere near 12 inches, even using an aircooled hood with a 16" fan cooling top of canopy. im thinking 16" light to plant plus 12" in the hope I get foot-long top colas 
this is the plant in question, in dwc system. the strain is Belladonna

Mr head is right in his response, the good ol' hand trick never fails. An alternative that I've been daring with is put it as close as you effin can- probably about 1ft (from bulb) for a 600 and look very closely at the pistils, if it's too close the 2nd-3rd node pistils will be brown and burned up. It's strange but typically the top ones don't do it although they're definitely feeling adverse affects.
Of course at your stage that really won't work. If the temp is Uncle Ben's recommended day time of 85F you should probably be highest cola to bulb itself at least 16". Like I said though, as long as there's no brown/burnt pistils you're probably not overdoing it; I see some of these every time, but I watch closely and move lights 4" every time things look iffy.

yeah, ill see how it goes as they grow up. I have a trial in another grow though not dwc so ill see how tall the colas get. thanks mate.

First time doin scrog and have a few Q's. I am 13 days in and plants are stretchin but now I have colas that are not as tall as some.
Should I cut out the lower ones or just leave them?
I did some trimming below the screen as I went along but have not since flowering.
Can I trim one last time this late into it?
Some of the colas above the screen have smaller branches coming from them with popcorn buds forming.
If I leave them alone will they take away from the main cola, if so should I cut them off?
I have more Q's but will wait for advice on these. Thanks.

what strain is it? indica/Sativa? stretch is almost done if Indica. I wouldn't cut anything apart from whats under the net and what's not going to become anything of note ie popcorn buds m8. if you have height issues then maybe some pinching n bending/supercropping. do it soon and let em go as I think your last chance for good tidy up is around 2 weeks into bloom. im no expert mind, so maybe wait for a real scrogger to post. cough cough
btw, they look great dude.thepodpiper

Thanks for the reply, after doing some research on trimming times I am going to wait a couple more days and give it the final trim. I have no height issues just want to keep the canopy as even as possible.

AH BLUEBERRY!!! mmmmmm
they'll prob stretch a little more for another few days, then start stackin n packin. extra +rep for the strain.

if that's 1000w leave 1'6" of photo zone, it will all get enough light to sustain itself in there. for a 6 probably do 1'. cut out anything below the photo zone, and especially leave nothing below the screen.
also your leaves are yellowing, get away from the high P-K for now and stick to a higher N with a little P-K on the side until youre at like 3 weeks left then you can focus more on sugar production after cola production has tapered off

so I've read through this entire thread and thought i would see what you guys think of my first scrog. this is the second time I've grown and just want to know what you guys think
set up is: 2 pro-grow 400x, 4'x8' screen and 5 barney's farm critical kush, fox farm nutes and FFOF soil.
day 15 of 12/12:
I was using cfls for the veg and this was while i was waiting for the pg400x's to come in
day 18:
day 24:
any advice you guys have would be greatly appreciated

Hey Cap, for a second grow you definitely have something to be proud of. Good screen, and the modular walls you got are pretty tight! Throw in a C02 supplement or two below the screen with a fan or two facing up; being that the grow looks like it's in an attic space not much C02 will get up there. That'll probably be the #1 improvement you could make, otherwise keep it up, things are looking great!
Don't expect massive colas with LED, expect a lot of trimming lol! In exchange for different development you'll get super frosty nugs as LED's create more sugar production, not to mention you'll never have any heat issue at all.
One thing the choir chimes in hard on this forum is that the flowering nutes can overdo it big time. Stick with you Grow Big, and mix your Big Bloom with Microbe Brew as they're both organic and probably work better together. Other than that you really only need tiger bloom a few times in flowering to max sugar production; the concentrates are way overkill and you will see leaf yellowing after using them too long as the ratios are way off for cannabis. I don't just say this because the ultra nerd forum heros on here are saying the same thing, but because I've use Fox Farms enough times to know what works and what doesn't.

sounds good youknowthekid! i had to go led because i didnt have the electrical power to run the hps that i wanted and the heat would have been way too much for the space. thanks for the tips on the nutes good to know

thanks yktk, by photo zone I'm guessing you mean the distance from the glass downward? I am currently using a 600w due to heat issues but I think I have those bugs worked out and will put my 1000w back in 2morrow.
My last feeding i added some 20-0-0 ammonium sulfate to kick the N up a bit.

keep us posted. I want to see LED's kick out some big danks
The photo zone is how far the light penetrates the canopy (generaly 1'-600 & 1'6"-1000w) to hit leaves with enough PAR to stimulate growth. If you're having amazing production then the photo zone will sustain plenty of life in some inches below it worth keeping on. Your goal should be to have the smallest nugs dry to no less than .5g IMO! You've seen everywhere, while looking at bud porn, that the best growers are getting solid .5g nugs at the base of branches up about 1'6" to fat colas when they're growing very effectively under just a 600. Top doggs under 1000w are getting 2'+ of premium bud zone; although 1000w prime photo zone probably isn't 2'; the fact that the nice even photo-zone created by scrog is being blasted nice and evenly unleashes growth.
Of course light distance also has a large effect. The excessively pushed 1' for 600 and 1'6" for 1000w works fine because most growers are doing that from the glass
and not the bulb itself. If the bulb was that close the plant would definitely get burnt out. REMEMBER it's always better for the girls to have the lamp 2" too far than 2" too close, I think

Did I read in this thread that SCROG is more suitable for Sativa based strains??
