I agree with you 100% on the genetics being a controlling factor.
could be all it takes is enough of us asking them to do it.

very good sleuthing mr holmes!
I've also have slowly come to the same opinion when your switch to hps the plants are stretching looking for the usable light.
dr shio posted this in the 1st few pages of this thread and falls right inline with where you went with it...
oh, and i used a solarmax 7200K when I saw the huge difference in yield and other side by side characteristics using it in veg and bloom

Dude!!! you just made my day! so maybe MAYBE! were on to something. Maybe if MH bulbs had more of a spectrum boost (like the 7200k along with a deep red) it should produce a overall better product?
I figure if i can get a Multispectrum MH bulb (not hps/mh mix) ill get better yields that are also more potent! This 7200k bulb is doing something i thought i would never do!!
actually if you read my results the HPS produced nice looking budz but the 7200K solarmax gave me considerably more weight, buds were bigger(see the pics),
and denser.
everything Ive read about the neccessity is in question after that 1 bloom run
and more people are now coming out showing Mh can be as good or even better than hps in bloom
I wouldn't bother with running 1 on 1 mh/hps anymore depending on strain
look at vapeg13's all mh grows in the 1st 1-5 pages.
phenominal grows using only a cheepo $22 sylvania 4200K bulb

So, if Im expanding my grow, what do you recommend I buy for lights? I currently run a 400w hps next to 250w mh in a 4x5 area.not sure on the spectrum of bulbs but they are cheap.I've been more than happy with the results. anyone who has tried my meds are more than happy with what i grow. I'll try and post some pics tmrrw. however, if I can increase my yield, call me corn, cause I'm all ears.
I currently grow my own meds. I'm considering starting to grow for another patient now that my garden is perpetual. I have the room to double the size of my flower area. If you were buying lights, what would you buy?? next run is cheese dog,chemmy jones, og chem,strawbrry blue.

I would say try to find a high output MH bulb 600w+ that has a spectrum ranged inside the red frequency and alittle of the deep red. The plants constantly need blue light to live so you would be adding more living power +you need to make sure the bulb has enough red/yellow
what I'm seeing and from others in this thread it really boils down to strain/genetics.
read through this entire thread and there are people that tried MH and some of their plants didn't do as well as hps.
you have to find what each strain prefers imo.
i would run hps and mh together and sort through it like that to find which strain prefers what
in my case my secret recipe did fine under HPS, but under a solar max 1000w 7200K bulb it blew the doors off that strain compared to a super hps horti eye.
as far as color range, some are using warm Mh's and I used a very blue 7200K and others are using a very inexpensive $22 4000k mh bulb and killing it.
to nail it down tight find out what plant go for Mh and then if you want to spend the extra time and resources nail it down even further from the warm deluxe Mh's to the far blue Mhs
btw I now have chemy jones 3 weeks in veg and I'll let you know how it takes to mh come bloom time.
I also have new chem og and cheese dog to run later.
I'll keep tabs to see how yours do under the lites
@ the gnome.
What strains do you think prefer MH over HPS or a mix of both? Currently I'm working with hybrids of OG's, headband, hash plants. So what I'd like to know is if you were growing these strains what ratio of MH to HPS would you use?
I've always tried to do it the traditional way. MH for veg HPS for flower. This run I'm trying 1 MH to 2HPS ratio to see how that will affect the girls

strains that excelled for me under Mh were
CGS-secret recipe,
DG-dieselrella
BOG_sour Bogglegum
GGG Candy drop+Leia OG
REZ-killer queen kush
this was by accident I found it out,
I started using MH along with HPS to see if I could coax out more resin in bloom and and noticed how well they did under MH.
SR did good under HPS, but under Mh it was bomb ass difference....
20% more yield, bigger tighter buds
even the popcorn down the stem did this
you'll have to do your hit and miss on the strains that prefer Mh in bloom,
but it seems anything with Diesel and kushes to do it up big time.
secret recipe has (diesel #1 x abusive kush) X chem BX1
dieselrella also...
and look at vapeg13s pics in the beginning of this thread.
double diesel and bubbaK seems to perform extremely well with MH
really no easy wayto find out other than to just start trying strains with MH
or do like you plan, run both hps and Mh, never heard of anyone having a bad exp. with both.
good luck rolldaddy and keep us posted on what shakes out

some strains i dont see a difference, potency or anything.
this one strain however, with hps only, very good smoke, but with mh and hps,
well, i smoked as normal, as i had been, rather lackluster strain i had been smoking before, so i toked 5 in a row of this particular strain
and suddenly i had the spins and felt like i was gonna pass out and puke, completely got the whites.
its been awhile since i was needing to be careful about How many tokes i have of a particular strain.
kinda funny how the 2 really strong strains i have grown , had really tiny buds.
with these 2 though, you dont mind it, im needing to smoke alot less anyway.
the other is a pure sativa and the superweed is some kind of hybrid, narcotic couchlock that makes you stagger yet has a nice uplifting quality to it.
im kinda thinking the blue in the mh (plus the uv probably, since i was using an unshielded mh.)
really brought out the sativa qualities in both.
ive read that some sativa strains need mh to really bring its qualities out.
oh and be careful with your eyes if you use an unshielded mh, i still sometimes have a bit of "snowblindness." after a few times of overexposure to that light. (its very vague, i have some weird vague white glare in the eyes, when im tired and its dark.)

I am using 1000w bulbs open so I might were my shades when go in my room. Haha
I'm running a few new strains so I won't be able to see how MH in the mix will affect. But with my current favorite strain conkushion (OG +MK ultra) I will be able to tell the difference.

oh id be wearing uv shades for sure.
i was only running a 400w mh.
shit and i thought the 600w hps was bad on the eyes.
(course i had the mh vertical (though i did have a "blind" between me and it, so no direct line of sight, still it affected my eyesight alot more than the hps ever did.))
now that's intersting SSO... and a nice discovery
I asked my tester about the difference between the secret recipe MH and hps... taste.. potency.
not much difference but once again
it seems the genetics control what and how things happens.
one thing i did notice
the resin heads did seem to mature a bit faster under hps.
so i think maybe switching out to HPS in say... the last couple three weeks would wrap up that resin maturation process quicker?

sounds like we ordered the same seeds.
i have 2 chemy j's,a strw blu, and a og chem, about 3-4wks old.the one og chem i think is a runt, because compared to the chemy j and strw blu, its about half the size.
popped 2 of the cheesedogs 2 days ago, put into a cup yesterday, already an inch tall.
As far as lights, im going to get two more 400watters for my additional space, 1 mh, and 1 hps. from everything ive read and from my own experience, mixing seems to be the way to go. we will have to compare results.
The soil i'm using is the the 3/1 ffof/perlite mix, u recommended to me in another thread.
hopefully it works as well as the previous brands ive used.now that's intersting SSO... and a nice discovery

i dont like using mh only, the buds get too leafy for my tastes.
i prefer hps over mh. but im not satisfied with it alone.
i use 600w hps with 400w mh, but im thinking 250w mh might be enough. perhaps even less.
i saw a difference using only 4 cfls 6500k 23w each.
healthier looking plants that kept their green longer. i did not see a change in smell or potency however.
with added mh, all the plants looked healthier and there was greater smell and better smell and with some plants added potency. vastly improved in some cases.
without the mh, some strains yellow up quick and gain a baddish odour like old jock socks.
others while not getting a bad smell without it, gain a added intensity to the smell.
i found that if i skipped the hps on some days, the smell of the plants would increase, kinda looked like a cloudy day.
i suppose one could use hps on most days and sometimes use a mh instead.
i certainly did it on really hot days, seemed to work favorably.
hps i find gives strong stems and fat buds, though not as good for the leaf growth.
i prefer hps for vegetative growth. (in that i rather use my 600w hps than my 400w mh in vegstate.)
since the object of the game is growing buds, not leaf. therefore i prefer at least 6 hps to 4 mh. 2 to 1 or 3 to 1.
its all strain dependant...leaf no leaf... strong stems weak stems....alot of trichs ect.
wheres the leaf with these buds? all mh and barely any fan leaves

yes, like i said, its all most likely strain dependant.
possibly growing in different locations gives different spectrums and presumably being grown under hps only for 20 years (quite a few generations.) has something to do with it.
and, also, our tests and observations are hardly scientific enough to be considered conclusive.
just possible waymarkers for those that will do the scientific tests on the matter.

hopefully you'll enjoy and get the results I do from the 3:1 FF OF.
Ive only grown(indoors) for 2-1/2yrs and its all Ive ever used.
Ive amended it for organic grows with bone-blood-kelp meals
its served me very well indoors and for my outside garden.
I get lots of compliments on my herbs and veggies.
I have a bale of pro mix BX and plan on giving that a go and stretch my wings a bit into other areas of the soiless side.
I also have strawberry dogshit... lol oh man! what a damn name
and some sssdh.
good luck mixing the bulbs,
its a good way to start seeing possible advantages with differing strains and spectrums.
so as for indoor growing we are about the same age.lol.
I wish i could figure out how to post pics.
Have a kandy kush x skunk and a ch9 super haze about 2wks from finishing. they look incredible. I've grown many different strains since ive started and all have liked the 2:1 bulb mix.
