Has anyone had any experience vegging their plants under hps and then flowering under led? I am currently doing that now, vegged under a 600 hps and now flowering on what is supposed to be a “1200” watt led. I think it’s a knock off as i cant find any information. Any how my plants don’t look particularly happy, my first time using a led so I’m not sure if it’s just that or if tbey don’t like the switch between lights. Anyone else found something similar?
I fell your pain I moved from 5200 watts HIDs to 1900 watts LEDs
mine are finally getting better after dialing in the environment a bright spot for
me is I will be outside in about 76 days
you need to put a meter on your light to see what it is drawing for power
10% less is about the watts it is putting out give or take a little
all the best
Thanks man i used a light meter and it came out at 872 ppfd which converted to 600 watts or something. I’m not really sure but I’ll carry on using it and maybe even put the 600 hps in with them to.
I veg under a Metal Halide, and flower under a led. HPS is for flower, not veg. This may be your problem, not sure.
welcome @grandaddy013 nice to have you here
you are correct Metal Halide is better for veg as the blue gives you a more
compact cell growth as opposed to the red which give you an elongated
cell growth (stretch)
I have done grows from start to finish which just MH or HPS lights in the end
you will get bud
all the best and be safe
A hps vegs just fine… i have been doing this for close to 10 years. Inunderstand spectrums and all… The question was vegging under a hps and then switching to led wherher or not it is to veg or flower. Do plants need to adjust? I knownplants stretch through veg to flower. I also know they stretch with the drop of hours, as well as changing from metal halide to hps i have found they also stretch from spectrum leaping… but my plants stunting out is new. Anyone with experience that sounds similar to this?
I’m not sure. Llike i said previously, i have vegged under a MH then led for flower with no problems.
I know the plants I have absolutely did not do so well going from cheap T-5 shoplight
replacement LEDs to real LEDs from say 170 PPFD for 14 hours a day to 500 PPFD
18 hours a day
and from mostly blue 5500 or 6000k to 3500k oops and VPD was stupid high
The Weed is a pretty durable plant but Autos are destroying inside
75 days or so out under the sun
a learning curve from the HIDs to LEDs and I have been growing since 1974
all the best and be safe
