Grow light upgrade importance
SouthernIndicastarted grow question a year ago
Importance of light spectrum? I'm upgrading my 5 small 15W lights with a 240w Grow Bar with Samsung LM281B diodes. My girls are growing and look fairly healthy but the speed is super slow. I'm installing the upgrade today, can I expect better results and speedier growth? 21w veg

Hey bud. The light is part of that battle.
Given the other things are in line. As in Ph , Water/feed routine. Environmental stuff (vpd,EC,DLI) it's a combo move ur pulling to recreate the outdoors.
But the improved light will help things along. Just need to dial in the rest.
Best of luck.

Hi!
From 75W of blue+red, to 240W of 3500K+6400K+660nm (what usually are on bar style fixtures), it's gonna be a huge change.
"Blurple" are bad, because they only cover two very narrow wavelengths, when the plants needs visible and invisible full spectrum (I'm surprised to see that blurple scam is still running).
But, in your case, the light power output is gonna be the more significant change (don't forget your shades 😎).

Nanners?Can someone verify my latest 2 photos look like nanners? If so, I’d love some insight on why my plants seem to be so light sensitive. Most growers seem to blast their plants with upwards of 200w with little issue. Mine is sitting at 80w 22inches and it seems to be struggling!5 years ago

Starting photos indoors for June transplantWant to start photos on a 14/10 schedule in April to match the lights around June 1st. Can I grow my babies on a 14/10 indoor schedule or could that possibly induce early flowering? I would rather not slowly adjust down from 18 to 14 before Xplant as suggested otherwiseSetup. Lighting

Wich of those cheap lights would be advised under 200€ and that would fit both final vegging state and flowering?
The grow space is 80cmx80cmx160cm and keeping in mind that the weather along with the lack of ventilation budget limits my options to colder leds.
Thanks in advanceWeek 1

Too close to the “sun”(light).... any advice?My plant grew close to 4x it’s original size during her stretch, 10-12” on day one of 12/12 to 46” tall. She’s on day 30 of flower and I set up a second ScrOG net. Other than blocking light to shorter plants, do you see any other potential problems this second net might cause?

Auto and regular plants in one box.I got an auto plant in a box, waiting for flowering to start very soon. Light schedule 20/4. Now I planted a new photoperiodic seed in a same box.
