I have had 5 plants under a 400w MH bulb for almost 2 weeks now and they are green as hell and have nice big, fat leaves but they dont seem to be getting taller. A few grows ago when all I had was an HPS bulb I didnt seem to notice this type of behavior so I guess my question would be does an MH bulb slow down vertical growth??? At the rate they are going I'll be retired before I can clone them lol (but really crying :( )
well i don't think it slows growth, but i know that it forms tighter nodes. so, best case scenario, your nodes are so tight you don't notice growth. hope it all works out, tiny.
stay safe

my guess is that it depends on the type of lights you are using and its known that HPS have higher Lumens than any other bulb so maybe thats a factor too. I find HPS bulbs are generally more yellow which i find makes them grow tall as well.
MH are more blue for veg. When I use MH for veg I run my light much farther away from plant just to get a little stretch. The HPS was making them stretch to the light looking for the blue spectrum. I had the same results.
well from the sounds of it atleast it seems that I have not been smoking to much anyways lol :jointsmile:
@Loc light is aprox 24" from plants and running 18/6 and really not seen any stretch at all. will post a pic or 2 as soon as I can.
i actually did a test last year with 8 clones using a 400watt HPS grolux (flowering bulb) and guess what? they all grew 'really' tall infact about 3ft tall in only a few weeks. after i began to flower them i was forever having to top them because they kept growing and growing and growing but it was all stick and few nodes.
from my little experiment i find its best to use anything that is ultra high in the blue and red spectrum and let them veg for as long as posible to keep them short and grow shed loads of more nodes. more nodes = more bud :jointsmile:
allowing them to veg just an extra week or more can really make a huge difference to the ensd result bit i top mine all the time while in veg to promote more nodes to grow while its as short as posible.
We have some in veg with MH now for alittle over 2 weeks and when I get the light 2 feet or closer they seemed to not get taller. We have the light at 3 feet and they got to about a foot tall. Now I lowered the light and they are bushing out some and not getting taller. I like to stretch them a little so the plant doesn't look like one cola. We will start to flower soon at about 18 inches and end up about 3 feet tall when finished.
They are 14 papaya with 2 hawaii x skunk x bigbud mix. They seem to be playing nice together. I like a little stretch and then bring the light down to bring out the branches. I never top, I use the light to control the hieght. We have 16 in a 4 x 4 feet area. If I went with less plants I would top and veg longer to fill the space.
First off, what are you talking about?Quote:

Third, MH bulbs are for veg and HPS for flower. I would only use a HPS for flowering and if I didn't have a MH bulb I would just use flouros instead of using the HPS.
Clones can typically grow faster than seedlings for obvious reasons. It didn't matter what kind of light you had, clones can and will grow about a foot a week once roots are established. Unlike a seedling that has to go through the "seedling" stage before it veg's, hence why clones are more popular. Your not the only person to do "little experiments". They market and sell these types of lights for these specific purposes for reasons ya know.
No offense, there are just too many variables in your experiment for you to be saying that HPS is better for veg when it actually isn't.
MH does keep vegging plants shorter and tighter, and whoever mentioned raising the lights is correct that it'll probably aide stretching a bit if clones are what you're shooting for.
As for using HPS for veg, while I won't say that it's any 'better' than a MH or blue-spectrum fluoros, I did use nothing but HPS for quite a while before I ever discovered conversion bulbs and switchable ballasts. I never could allow the plants to grow vertically, or they would have damn near reached the ceiling, but I did get to do a lot of experimenting with LST methods due to the extra stretching, as well as topping/FIM techniques which I believe may have improved the eventual yield.
So, all in all, HPS in veg might not be ideal (depending on what you're looking to achieve), but it works in a pinch, and in this instance, would almost certainly have assisted in cloning at such an early stage.
Just my :twocents:, for what it's worth.
erm point out where i said HPS is better for veg????? cant see it, i dont see it either ;) i said i once tried using a HPS for veg (as an experiment) and did NOT say it was best. read what people write 'before' you criticise them. of course other people have tried experimenting you wouldnt be the first either. from what you wrote about my post you seem to be on a high horse strait away with no reason, i suggest not smoking too much before reading posts because you obviously dont read them rightQuote:

First off we all need to play nice, we are all here for the same frigging thing ..... to grow and help others grow the best smoke we can so we can enjoy life just a lil bit more. I have been reading these boards for quite some time now and I read them twice daily, my girlfriend will vouch for this as she sits and watches me read hehe. lets all just ease up and enjoy.... /rant off
Now then I took the pics and raised the light a foot so it is now 3ft from top off plants (ty Loc :thumbsup:)
as for pots ... no gots I do E&F hydro and those are 4" RW cubes that they are sitting in so you have an idea of size. they will be 4 weeks old friday the 17th, using LW recipe for GH 3part so atm they are getting 5/5/5 ml per gallon (micro/grow/bloom) and 1 drop Superthrive per gallon. PH is 6.0
Please...by all means...point out where you answered the original posted question regarding MH and stretch, instead of dancing around the spectrum...? (I don't see it either)Quote:

MH in flower can restrict stretch, but I've never seen it restrict stretch in veg, unless it's too close. MH bulbs seem to burn hotter, so might need to be kept a tad higher.
Tiny: did you switch ballasts/lights in the midle of the grow cycle? Might be that the plants are growing accustomed to the new colors, and should likely resume 'normal' growth soon.
Have you tried side-lighting supplimentals to give the side-shoots (future clones) something to aim for? (CFL's work fine for this)
Hey Mr. Clandestine, long time no see. Wazzzup?
I'll definitely second this. Very cost efficient way to add some extra lights without adding too much extra heat. :thumbsup:Quote:

You just keep asking your questions and I'll keep answering them.:thumbsup:
Sorry I DO medicate for medical reasons. You wanna come at me about my meds. Your just using to get high.
Rusty, no i didnt switch. as soon as they sprouted they were under a couple of 6500k cfl's until they were big enough for the 4" blocks and the E&F tray with the 400w bulb. I raised it last nite about a foot so now about 36" from top of plants and they might have actually grown a lil, hard to tell after 1 day but will tell for sure by end of weekend.
Lit, sorry for the harrasment :(
Tiny I hope that you get it sorted out I guess ima watch round to see if you get it figured out. Guess there is alot of stuff I need to pick up still so I am curious now. Good Luck:jointsmile:

It's fine Tiny, he obviously took offense when I intended no offense.
I think that you will decide what you are comfortable with.
ok day #2 of increase of height by 12"s of light and no doubt have a change in vertical growth. tomorrow will be installing new fan on cooltube and doing weekly res change and at that time will raise light about another 6"s or so and report back :apachecopter:
Thank You Loc as I believe you hit the nail right on the head!!:thumbsup:
Sounds good man. Glad to help. I just got most of my bro's papaya up to 12 inches and have brought the light back down to 2 feet and the branches are starting to come out now. They are in 3rd week of veg and will be ready before the end of the month. I might move the light up and down 1 or 2 more times to get the desired affect without topping. I just like that main cola but I get some good branching too.Quote:

I really like doing the clone thing alot better than seeds. Friggin seeds take to dam long lol, I am not one who likes to sit and wait for things. anyhow this is really turning out to be an educational exp and will see if this light height adjustment works on the clones also :cool:
Private PotHead over and out for now!!
:s4:
quick update for you all, raising the 400w MH light about 18" did the trick. We were able to pull off 5 clones last nite and start them under the dome and tonite the MH went off and we have darkness until Sunday when the HPS comes on and flower begins. When clones go under MH light we will play the light height game again and see if get same results.
once again Thank You Loc for the light height input, kept me on my time schedule :jointsmile:
Great tinytoon. I used fluro's alot to start and when i got the MH it kind of had me in the same spot. After a few light up light downs my bro is a week ahead of time and just went 12/12. Seems they are very strong lights. I wish I could keep mothers under them so I had the control when I need it for clones. I got 28 clones now and at 8 days about 7 or 8 are showing roots and I need to take abot 30 o 40 more off the mother. Wish I had more bro's That i could setup here, but they will veg longer and be topped for max bush .
I got one bro that's killing everything I give him. It's almost funny I tell him what he needs and what to do and check on him regularly. Then he listens to some dumbass that tells him to piss in the hydro tank. LOL. I tell him 5.8 ph and 2 days later his dumbass tells him 7.5. It's just for fun the cuttings would be on the floor anyway from trimming back.
