Going to do a room with 2 1k watt hps and 2 gavita 1700 Leds side by side and i want both trays of plants to be the same size when i flower them does anyone know if the hps side will grow biger then the LED side or will they be same
Mmmmmm....if leds contain mostly blue light then why does the spectrum of a 3500k light have so much red in it when it is only one color temperature, no red diodes? 3000k has even more red, still no added IR and UV.The hps side will stretch much more than the led side. Also I am guessing plant structure will be very different.
These led “white” diodes are really just blue phosphors which are mostly blue light which keeps plants short and leafy.
Red spectrums promote stretching and branching. Thats why they have begun adding the red diodes. To grow more like hps did.

Check out medgrower1 on YouTube, his plants are lanky/stretchy and he uses leds. I believe it comes down to the genetics, type of nutrients used, and the growing style (sog,scrog, etc) One day, someday, we will figure this shit out lol. Probably not, but hey we try, we try.Looks that way but the plant growth shows otherwise. Its not mostly blue light the phosphors on the diodes change the color but obviously not as much red as hps.
Also an hps is like 2100k.
And i have been wondering how they come up with the color temps when they all show different spectrums but call them 3500k.

i have 3 different sets now of qb288s I have to say im loving the 3k/4k mix over the straight 3500k diodes. I can definitely see a difference in the tent. the blending options when you start talking potential supplements i mean sky is the limit.Of course there are tons of variables and every grow can be different.
And the led’s can be configured and even used differently.
But the question was will the 2 tables be the same for flowering and my answer is no. The hps plants will grow different than the led.
This is just my opinion based on the data i found. You can find lots of data to swing either way. But to why i dont opt for the UV diodesMixed spectrum is definitely where it’s at. Having LEDs one color temp does not fill out the spectrum curve like mixed spectrum. I’m not sure UV or IR are needed at all(with quantum LEDs). Imo they are just gimmicks to get you to buy their rig over someone else’s.
Ouch sounds expensive, like previous dude said hps may be more lanky since it’s mainly for flower, MH is known for giving tighter nodes. That being said the led side may be smaller. However, the plants do grow pretty fast under leds, and that gavita will push them to the limits. Hope u plan on running C02 and controlling your environment according to the VPD chart cuz that’s the only way you’re maximize all that light. Experimenting is fun, but there are so any people that have documented their grows with HPS and led and I think led is the way to go. Less heat, more efficient, and they last for YEARS what more could you want? Not to mention, you can veg/flower with half of the amount of electricity you’d burn using hps/mh, essentially making you richer by saving you money on your electricity bill. 👁👁
That will make for a very interesting comparison!
I bet that HPS side will stretch a bit more if u use em for vegging plants...
