400w hps...

[teachme18129111]

Why do I keep hearing that I cant get more than a 2 oz harvest off 5 plants under a 400w mh for veg than a 400w hps for flowering? What is a realistic yield with this setup?

 

[smokinrav]

Quite a lot, depending on a number of factors.

But all things being equal, I'd expect around 1.5 - 2 oz per plant with a lot of veg time and training.

thank god someone replied...I'm thinking of trying Uncle Ben's topping technique for 4 main colas...and vegging for atleast 7-8 weeks. Decent idea?

 

[teachme18129111]

also using FFOF with FF big bloom, tiger bloom, and grow big

 

[smokinrav]

Yeah, I hate topping as a technique. I prefer LST supercropping. Low Stress Training vs. lopping the most developed top off your plant.

Look them both up before you decide.

 

[Trichyn9ne]

I agree with smokinrav...I believe lst is the way to go. I grow with 400's and use the same method. Lst all plants and lollipop the crap out of them!! Check out my grow journal

i put 8 plants under a 400 watt hps and within 3 months or so im getting 2oz off EACH plant. using all fox farm stuff

 

[Cobnobuler]

Sounds about right depending on the strain. I run 400's MH and HPS and yeah, bout 2 oz I put up a 70 grammer on one of my last harvests !

Under a smaller lamp I've found that I get more out of fewer plants that have vegged for awhile, than cramming in more plants. Once you get your strain dialed in, a sog with more plants can give more.

My advice for a 400 run no more than 3 and give them at least LEAST 4 wks veg.

You can't get more weight than the light presents, weather its 6 plants or 1. To gain an advantage it's all about style. Keeping the bulk of the bud sites at the same elevation. Like smokinrav presented, training is good. My self I don't mind topping, but it has to do with my own growing conditions.

Work with you own personal conditions and you'll do well.

If you are a true expert and do everything right, you can hope for 1 gram/watt, that's just under a pound - about 14 oz. I doubt if you fall in this catagory.

If you are a "Fair-to-middlin'" experienced grower, you can expect about half that much, or, .5 gram/watt - about 7 oz. Most growers would be satisfied with that amount

If you are a rank Noobie (sorry, the question kinda gave you away), you can consider yourself lucky if you end up with .25 gram/watt - or about 3 1/2 oz. Of course, that's if your plants survive that first grow. Sorry if that seems a little harsh, I'm just trying to be realistic.


A few first time growers seem to do most things right (totally by accident) and wind up with a decent yield, maybe around .5 gram/watt. Next grow they fall back to .25 gram/watt, or worse yet, kill thier plants because they don't really know what they're doing.


The bottom line is, it's all about repitition and experience.

 

[smokinrav]

So if I manage to yield 8 ounces dry out of a pure sativa under a 400 HPS, I'm just a middlin' grower? Sorry, but pigeonholing grower experience and success into yield categories is just silly and ignores the variances in strain and race that affect all harvest numbers.

You just took a huge shit on my hopes and dreams.....lol..Idk though 2oz per plant sounds doable. I'm already halfway through my first grow with 3 blueberry girls from seed. I'm not experienced..but I'm no idiot.

veg them for longer and use pk boosters and boost accelerators and foia feed and u will get more, use a cfl for side lighting if need be

holy shit pulling an lb 3/4 times a year? care to share your methods? we have pretty much the same setup...you can pm me if you want

 

[teachme18129111]

[/B]veg them for longer and use pk boosters and boost accelerators and foia feed and u will get more, use a cfl for side lighting if need be[/QUOTE] Any suggestions for lst/topping? is uncle ben's topping technique for 4 main colas a bad idea? Also, cfl's for side lighting in veg or flower? Only because I have a veg and flower room

 

[brewing up]

'cfl for flower (red) or cfl to veg (blue)' .. topping does work you need to veg for longer after you cut it to let the branches grow up

I doubt if anybody falls into that category. I want to see pic proof of a 14oz yield under a 400hps

gotcha on the cfls, and yeah UB's technique is to cut the main stem at the 2nd node after its grown to 5-6 nodes. So I assume I'd let em veg atleast 4 more weeks after topping

 

[mighty g]

Is ther a specific height you guys are shooting for to get these huge yields?

So if I manage to yield 8 ounces dry
I wasn't responding to your question, I was responding to the OP; whatever you are capable of yielding has no bearing on what someone else might be able to do.

out of a pure sativa under a 400 HPS, I'm just a middlin' grower?
Again, the OP said nothing about "sativa" or any particular strain (that I recall) for that matter. News Flash, my post had absolutely nothing to do with you. It was a very general question, comming from what appeared to be a Noobie. A later post confirmed that when he said he had just finished his first grow.

Sorry, but pigeonholing grower experience and success into yield categories is just silly
You have every right to believe that! But if you truely believe that Noobies don't suffer a higher failure rate (or at least suffer from "Low Yield" a lot) - then I've got some Real Estate in Florida I'd like to talk about! Perhaps you hadn't noticed, but it's the Noobies that ask most of the simple questions and make, by far, the majority of the growing mistakes. If you don't understand that; you must be looking in the wrong place, or else you are just naive.

and ignores the variances in strain and race that affect all harvest numbers.
Granted! The whole point is that Noobies make more mistakes and have lower yields because of that fact. Hopefully learning from thier mistakes is what constitutes experience. The whole friggin' world works that way, why should growing pot be any different?

By the way, I'm not knocking Noobies - everybody has to start somewhere. The whole growing experience is a "Learning Curve". I'm sure that some Noobies have great 1st or 2nd grows, that just means they did something right (either by doing thier homework, or just accidentally). That doesn't make them an expert, it just means they are on the right track.
