When to attach scrog?

Hello!

I'm not sure when to attach scrog.. my plants currently looks like this and I would like to switch to flowering soon:




They are about 40cm high and tent is 90x90x180cm.

Should I attach trellis net now, lets tell about 20cm above plants, switch to 12/12 and use advantage of boosted growth to fill the scrog? Or better to attach trellis net and keep them on 18/6 until scrog will be fully filled?

Thank you very much!

You are pretty close - but if you want boosted yields, add a SCROG net now. You can put the net about 18" (45 cm) above the floor.

Yes, leave your lights at 18/6 for a bit longer. You are not finished with your VEG cycle quite yet. As the branches grow up through the netting, weave them in all directions through the net to keep them growing laterally and fill your tent from corner to corner. Once your SCROG net is full and you have 3' x 3' of woven plant material, flip to 12/12.

About 4 weeks after flip, stand back and say "You mean this bud is all mine?"

I'd put up a screen and flip to 12/12 now or in the next few days. I think if you wait much longer you are gonna start running out of room once you hit the flowering stretch.

i see no reason to use a net for your grow. you have a even canopy already plus looks like you have allot of head room for stretch.
you could still add one now to help support the plant but i doubt it will need it

I don't run into that problem with my net 17" above the floor in a 5' high tent. With the extra foot of height, that shouldn't be a problem.

While I agree that flowering now is gonna give a pretty nice yield, the original question was about maximizing yields using a SCROG net. Should he/she chose to add one, the SCROG net will fill in those empty spaces in the corners and maximize that 3 x 3 to help further maximize yield.

Really depends on the strain and the light being used. Some strains will streatch like a MF, others not so much. Also you need a lot more headroom for a 600w hps vs a 250w led panel. I use a 600w hps in a 4x4 then, but I only fill up the canopy to 3x3 because I want airflow. A bigger yield isn't gonna mean anything if it's full of mold, mildew, or larfy buds.

Very true ... strain and genetics will have a say in the stretch. I use 560 actual watts of LED's and both the Red Diesel and Blue Cheese didn't stretch as much as I had thought they were. I had expected about 2' and upwards for stretch but it only stretched about 18".

I did make the assumption that there is enough light to properly flower a 3 x 3. If there isn't at least 400 W spread evenly in that 3 x 3, the outer edges will be LARF.

I run my net 8" high. My GTH#1 clones have to be trained from the time they're rooted until the 4th week of flower. I have to top her going into flower and flip when the net is 50% full. She will overtake your garden in a heartbeat. She will stretch 4x her original size. I wouldn't recommend her to newbies, For me it's worth it. She has Massive yields and a potency that still puts seasoned smokers on their ass. You have to work with a strain a few times to optimize your stretch and know when to flip.

Thank you all... net attached now just fill it :) it's my first indoor grow and I want to have really square of buds as I seen over internet haha. Just what im little scared of is reservoir cleaning but I think I will just unhook trellis net from tent construction, leave it on plants, clean and then just hook it back..

I’m running 13 plants (4x4) under, 7 gal pots, 600w in a 4x8. Plants are about 18’’ tall from the floor. Within the next week, I plan on moving to another space with a 1000w gavita, 9’ ceiling for SCROG. If I flip right away after the move, think I could get away with the 13 plants under 1 gavita? I figure the gavita should illuminate 5x5 pretty easy, maybe more? There a 4 different strains here as this is my pheno hunt so to speak. I’ll clone my best for next cycle.

Thoughts?

Lower plant counts, or clones are better suited for scroggin.
Pheno hunting in a scrog could get complicated/confusing. Sog would be a better choice

Just a smidgen under 12 oz. Using Viparspectra blurples - and those lights have given me lots of very good and potent bud ... but I still think the nuggets could be a bit fatter. The one thing that I do regret was not going the QB or COB route when choosing the lights. I would probably have closer to 20 oz with one of those rigs.
