Can’t yield more than 2 zips a plant

Hi

I am after some advice. I am struggling to yield more than 2 zip a plant. I am on my 5th run now and so far averaging 1.5zip a plant. My set up is as follows

-veg for 8 weeks under 250MH
-Flower under 250w hps dual spec
-Carry out low stress training during veg to flatten canopy
-Growing in coco coir. 16 litre fabric pot
-Feeding general hydroponics and vita link calmag. Rhizotonic in early stages to help roots. Did use Advance Nute big bud on one of grows and didn’t see that much difference.
- temps and humidity are where they should be in veg and flower.
- I have an oscillating fan and a 4 inch fox exhaust fan and filter
- Running with Barneys Farm Blue cheese at the moment.
- not suffering any burns from what I can see.

Can anyone think of anything I am missing? I am hearing of people achieving 5zips of dried bud a plant. My plants look healthy and produce some nice tasting bud, but just not a lot. Is 2 zips of dried bud a plant all I can hope to achieve?

Any input would be appreciated

You should be able to do 1g/w with hps. You have a really long veg.what kind of trening do you do? How many plants?
Maybe you are overwaterring that can stunt grow really bad

The last time I looked a 250 w for w was only a little less efficient than a 600w, imo there's something else wrong somewhere, feeding or environment?

Treating coco like soil, methinks.

Bullshit!! How do you make bigger roots in a soil grow? I grow in 5 gallon pots and yet have never seen the rootball exceed 50%, EVER!

OP, 1.5 O per plant is not all that good, you should expect 3 at least. I get 3 O per plant under 600 HPS but get the same with 400W LED, just don't get quality under 12" of canopy. I run that in an ISO.

Look up VPD, dial yours in. Transplant using myko, water with recharge. If your roots aren't absolutely ridiculous after this I don't know what to tell you man. Not sponsored or anything just sharing the knowledge I've gained. I had plants not taking off or dudding out too and using vpd/myko/recharge has made my plants look much healthier the past year with much bigger rootballs at chop

If you could add as many details as possible in one post.

Your area size, light, your temperature and humidity day and night, how often do feed and what with including ph and ec, a good clear picture of the full plant and any other details you think relevant.

With the right environment, feeding there no reason you shouldn't get 1gpm +/- with a modern hybrid, the wattage is more about footprint than yeild, imo 1 gpw is a good benchmark.

They’re not. They’re less efficient than cfl tubes even. Low wattage hid is next to useless, and decent lighting is pretty cheap these days. For around $200 op could start doing real good especially if the only issue they’ve got is a small yield.

I've only used 250s in veg I've never flowerered with one so I I couldn't argue the point, I was basing it on the figures from the manufacturers, I've grabbed this from Google as a example.
1gpw holds true with 400/600w so I'd expect it with a 250w.

I agree with the consensus. As long as you’re running 5.5-6.25 pH, the only limiting factor I see is light. You should spot for an LED panel. I have a Mars Hydro ts2000 and 3000 and they seems to do the job well.

My setup is virtually the same as yours. I’m harvesting end of this week.

not really he could have bad food low airflow.too much water bad VPD...... light is the only constant really. well maybe if he has the light too high or something...
he didnt even write his temps

How to Select the Right LED Wall Pack to Replace an HPS Wall Pack

Selecting the correct LED wall pack to replace a high pressure sodium wall pack is challenging. Here’s what you need to know for a successful upgrade.

1gpw holds true with 400/600w so I'd expect it with a 250w.

I can hit 1.5gpw with a 600w hps pretty consistently, but manufacturers data is often exaggerated, 1gpw is doable with a 400 but not typical. I run mh between 250-400 for veg too and it’s fine. Actually like how mh vegs better than led, love that tight node spacing 6500k lighting brings. You get more stretch with leds since they’re usually more red.

250 watts isn’t going to yield much and he’s had the same lighting across multiple grows. If he’s getting a constant result, then I would personally start with lighting. Micromoles matter.

Nothing he’s written leads me to believe he’s done anything wrong. Leaves aren’t showing stress, he’s in Coco/cloth so overwatering is unlikely, and has air movement.

Heat stress would show in the leaves. I suppose too cool could account for a smaller plant, but he states his temp and humidity are “where they should be.” Which I assume is 70-75 40-50%. You’re right though, he didn’t list them.

You consider 8 weeks a "really long veg"? Shit, depending on genetics, it takes closer to 3-4 mos.' veg for me to yield >2 oz. and plants get plenty of close proximity LED light in bloom. Topping adds time. Not 3' tall, more like <3' wide.

Yep, I veg no less than 10-12. I want beefy branches before going into bloom. If you’re using sticks to hold your buds up you’re either doing it REALLY right or you’re doing it wrong. Ha!

i don't know last grow i did 15 days veg(started flowering around day 21) but it was a 60W grow got little more than g/w. but when i did 400W hps i would do 30 days 4-6 plants little less than g/w

ts2000 is 300w led with a ppf of 716 umol/S
Ts3000 is 450w putting out like 1000umol

your setups are worlds apart as far as lighting goes. A 250w hps puts out like 100umol which is not a lot.

More light. That's what you need. No bottled or bagged product is going to fix your lack of light.

250W HPS is not a lot of photons. you need 48 of them to make one glucose molecule from CO2 in the air.

Very nice setup, 250MH are really good light for veg and the 250w HPS is a great choice too, the lights are dated so most the reply's are going to be from growers that have never used these lights.

Used to veg my plants for 4 weeks under a 250w MH, they are a powerful light in a 2ft x 3ft veg room, 2 x 2.5 in flower (only problem is they run hot in this space), I would flower 2 plants off under a 250w HPS, should pull between 3-6 oz's 1.5-3oz's each
great for short bushy plants. aim for 6 main cola's on each plant.

While I grow trees in 20 gallons of Promix BX per plant. I also start seedlings under 1000w Hortilux HPS, and use them all through veg, and flowering. I get no less than 18oz from one plant, and if conditions are right, Ive done as well as 22oz from 1 plant.

I also dont top, but bend my plants over. I look for strains that stretch like a MFer in flowering, which reduces veg time.
I veg for 60 days. Strains I can pull this off with are Mr Nice Super Silver Haze, which I F2 2 packs, and went through 250 females, though more than a few met this output. I picked the one I did because of potency. Ive had this clone for 8 years.
The next strain is a 2010 clone of Barneys Farm G13 x Haze.
2004 clone of Willie Nelson. This stuff only needs to veg a month, and it gets huge. It stretches for 80 days after flip. Takes 100 days to flower. Ive done 16oz from a 5 gallon container with this strain, and when bent over is 6 feet across.
Everyone of my plants are totally rootbound in 20 gallon containers when done. Temps are between 78f-85f. I have great airflow.

Last harvest I used 3x Hortilux HPS. 6 plantts in 20 gallons Promix BX, and 5 plants in 5 gallon containers. Production was 80oz.

By comparison, I can get only 8oz from C99 in 20 gallon containers under the same conditions. Same for Dominion Seed Company Granny Skunk, Local Skunk, Dominion Skunk. These strains dont stretch much in flowering.
Both the Mr Nice, and G13 x Haze stretch 5- 6 times their size.
The Willie Nelson will stretch 8 times its size under the right conditions. You really have to give it a very shot veg time. I also often start them under 12/12 to control them.

My grow space is 13 feet x 6 feet, though I use about 12 x 4.5 of it.

That's quite an assumption. Many, myself included, have used them previously and have migrated to more efficient (better) LEDs as they became available.

A 250w MH/HPS is better than nothing, but pales in comparison to even the low-end 150w LED alternatives.
