These are nearing the end of 4-weeks in veg. Not counting the 2-weeks or so as seedlings. I'm eager to flip to 12/12 but need to fill this screen more before the flip. At this rate, I'll need to veg for 3-4 more weeks, which I'm not inclined to do! Can I raise the lights to get them to stretch a little? Does anyone have any ideas?
You haven't been training. Youd have it halfway full if you had it laid open a month ago letting light through the plants canopy instead of all bushed together. Have to start training around a month. Just letting it grow bushy itll just keep growing bushy and up instead of how you're wanting it to grow. Also one plant in a 3x3 or 4x4 you're looking at a 3 to 4 month veg to fill the tent Yea training holds top growth down while inner growth further from the light stretches up towards the light evening out your canopy at the trellis. Normally youd want to lst or hst starting pretty early and often so by the time you use the trellis your canopy is already full and even. Using a trellis to train will cause plants to grow outward towards tent walls, in doing so that shows all the secondary sites you basically only want the main colas and like a foot down above trellis everything else comes off. It's fine growing like that just makes for a ton of smaller nugs
You need to actually start training and start putting branches in holes and force the plant to start pushing outwards.
I would raise the light at least a foot higher. You can force stretching by making the night time temps more than 10 degrees colder than the day time temps.
My tents and my outside grows get more than a 10 degrees difference never has that effected plant stretching. Good ole broscience. My outdoors is like 20 to 30° swings
Thanks for the input. I think I'll reduce the light to 50% and then raise it about 12"-18" for the next 7-10 days and then flip. I get what I get. These are gorilla glue 4 plants and I have topped, fim'd, and defoliated but the node spacing is tight and not a whole lot of vertical growth. It seems to want to stay shorty and bushy. Maybe this is a strain trait? **EDIT** Another thought . . . maybe having the NextLight Mega Pro 12" above the plants was too close and the intensity didn't allow them to stretch?
Do you have any red lighting or flower mode, put it on flower mode but keep it running 24/7 red spectrum induces stretching, or you could do the old trick wich will probably help better. Switch to 18/6, they will stretch all through the dark period, run flower mode on your lights and 18/6 if you don’t have red spectrum as a seperate switch or sup like tap to add. Just switch to 18/6, then U don’t have to turn power down, ur still hitting them full force but prepping for flower with intensity and lighting switch and no it won’t start them flowering. But it will show u sex
As far as I know red helps in photosynthesis mimicking the fall sun. They will stretch anyways because reds are used during flower. I've used 630 and 660nm to veg with with a eye hortilux power veg start to finish bulbs my ROI-e720 has reds never do plants stretch under the ROI-e720 nor did they stretch under the florescent. Hell my blurple has reds as long as light is at a good distance they dont stretch Red light is ideal for flowering cannabis, resembling late spring and early fall when cannabis produces buds and finishes its season. Wavelengths between 600 and 700 nm are the peak for chlorophyll absorption. They heighten flower and resin development for abundant harvests of fat colas.
Just to clarify, I am on an 18/6 light schedule and am top feeding with drain back to the reservoir. I just got (2) 4' Kind LED X80's to add red during flowering. I'm going to go ahead and get those hung and start running them too for the next 7-10 days.
Ok we believe all studies now as mentioned I use it in every phase of growing or have. I've never had stretchy plants. I can go off of a study or what I've done and seen over years. Think imma go with what I've experienced vs reading what others say I didn't reply to you or quote you, nor did I have a problem with what you said. As that's your opinion for whatever reason a study done your experience etc. I had a different opinion than yours dont feel the need to go back and forth. If I wanted that I'd spoke to you directly instead of just placing my differing opinion.
If you want stretchy plants grow in a window sill or use inadequate lighting. Keeping the light raised to top of tent can make them stretch. Let them grow into the light raising the wattage as they grow instead of the light
I added (2) 4' KIND X80 flowering LED's. There was no easy way to attach them to my existing NextLight MegPro. I have the lights about 10" - 12" above the canopy.
Damn 400 bucks 200 dollars a piece for 80 watts each. They are still blurples send those back. Shoulda either got a saber or UV light from hlg. Blurples in no way shape or form are in any comparison conversations as of yet, maybe one day. Those dont even list the wavelength they emit. I understand you want red those dont provide you need between 600 and 700 nanometers. 630 and 660 are good ones I've used in the past
I think I'm good . . . the red spectrum is PERFECT and the 3-year warranty more than makes up for the few extra $$$ that I spent. I promise I'll get my $$ outta that warranty!!!
If you say so bud run the hell outta them blurples. That may have came off not the way I intended. That's alot of money for that style of light. You spent enough for a 3x3 light on 2 add ons better quality on the market for equal or lesser value. I spent over a grand on bs lights before I realized what I actually needed. Why I try to help others from making that same mistake. Good luck bud Honestly I would stay away from amazon for all lighting needs. Too many options alot of bad information, very few on Amazon are quality 90% are bs
So if I bought the same exact light from Hydrobuilder, it's all good? I have > $12k invested in that grow room. I could have saved $150 and gotten a cheaper light (not necessarily better) with a 1-year warranty. I'm not sweating a few $$. I'm certain I'll be happy with my harvest
Blasting the plant with more light isn't going to help it stretch out anymore, quite the spendy purchase on those bloom boosters, I would wait before using them, really overkill at the moment. Hopefully you've got the light up a foot or two and the plant has been able to stretch and get tucked along the trellis.
