all good info. for the most heaviest buds, probably best to start 12/12 with a HPS bulb.

I use a Metal halide for the first 3 weeks of flower it's slows the stretch and keeps bud sites close forming denser colas, after that put in you HPS. I use T5 for veg.

Decided to research what you said and basically MH is only good for displaying plants so I'm going to stop spending a lot of money on MH bulbs now. Thanks Hawk

Don't get me wrong, its fine for veg, but in reality it's just an added expense that's unnecessary. If people want to switch between them, more power to em. I just don't see any point in spending more money when it really doesn't give you a better yield.

That's good to know, I'll stop wasting money on them in future grows.

And like I said, that's totally fine. It's not hurting anything. It just isn't completely necessary.

So this is new to me also. An cool/great to know.
So are we going to jump out and say that t5's then may be the
Most cost efficient and most suitable means to veg?
If you aren't gonna hps all the way thru I mean....
Guess I wanna know the smartest way to veg,
sans mh if it's basically a useless piece of equipment.
Bang for buck? Guess it'd be t5 4/5000k but the hps would do more work but typically costs more and is a bigger issue to cool...
Interesting stuff
Cheers

MH useless, now that's rich.
Those only worried hlgher yeiIds would believe this. And I'll admit it works for them. But that doesn't mean it's best for the plant's health. When growing For max yeiId you generaly sacrtfice quality.
If I wasn't posting from my phone I'd go into greater detail.

please explain when convenient.. I'd simply like to know what Is most effective..
Rosenthal claims they actually lack blue vs hps and hps of course has other peaks also...
It's interesting and then plant health under t5's any different?

Who said useless? I said that they aren't really necessary in growing. And professional growers don't use them. They are using HPS mixed with DE.

If you follow the link above, the other guy posted..
It ends up with rosenthal claiming that they (mh) are only good for "display" meaning, his claim is, that mh is a useless part of the equation.. I feel like that is inaccurate, tho. Knowing the blue put out by mh much more noticeable, I dunno except that hps produces a bit more light in general..

DE are a type of HPS. Different than your traditional HPS. We need to separate single ended and double ended when talking about HPS, as they are two entirely different beasts. Most professional growers that have a mix of DE and HPS are usually just slowly transferring over to DE, as they have been reporting increased yields with DE over traditional HPS.

Of course, why would you want to change over 60 some odd lights just to get a fraction of different growth during veg? It's just impractical and doesn't give you any real benefits in the end. Although if you are running that many lights, some growers will throw in a MH every four or five lights to broaden the spectrum, but it's not really needed.

I guess it comes down to personal preference. I use 1000watt HPS to bud. vegging with the T5 would be most cost effective. I mean why use all the hydro 1000watt MH requires just for 3 weeks of veg. I'd rather use my T5s for 5 weeks instead. I guess it also depends if you have a separate space to veg.

Well you would have faster growth with a more powerful light. So less time in veg....

I do agree, however I like to harvest every 10 weeks and Thats how long my bud cycle really takes even if the label says 8. So I would need 2 weeks 18 hours and then flip putting me back 2 weeks. Or I can sprout seeds when they are 5 weeks old and veg until their ready to go into bud. By the time their ready to go into bud my t5s has them ready. But yes the larger light would make them grow bigger faster. The only reason I had the MH is because I read something along time ago saying that it slows down the stretch I used it for the first 3 weeks of bud to try keeping bud sites close together, I've adopted new techniques since that time so I figure I'll stop buying MH bulbs not saying everyone else should do the same this is just what works for me.
