Yields at differant PPFD?

You are doing so good now why change anything. 2 lbs. off 9sq feet is almost unbelievable .
Yeah I've done 2-2.5 in my 3x5 and it was very crowded. Crowded to the point where yield would be effected if I had vegged them out bigger. I can't image it fitting into 65ish% of the space.

Actually 42" x 46" stealth. 7 foot clearance. 6 5 gal buckets of promix. Down to 5 now. Got rid if the male. I see 1100 grams of bud when I grow the right strains. Peters fert fed at 1.3 ec now. Calmag and feed each water. Bog lsd and timewreck this run. Above 700 I don't see much difference. I keep clones so I can see a difference. This is my first full run with the 3590's. I was using Vero 29's. The growth is amazing. Inches a day and I just flipped. Lot's of LST coming. Maybe I can toss up a pic. At work now. Heading to Wendy's for a chicken sandwich and some White Widow. I may have to climb on a machine tool after lunch. I'm gonna get high.

got any pics? I would love to see 2 lbs in a 3x3, or a grow with 3.5 oz /sq ft. Never heard of anyone pulling like that.

Agreed.
Not at the moment. Ill be starting a flowering journal next week in my 3 x 3 and will gladly upload weight at harvest. Been getting just over 2 lbs in my 3 x 3 for a bit now. Have it dialed in. No Co2

Only reason to change is im upgrading to a 5 x 5 to do a few runs then to a 10 x 10 canopy space.
That being said I am using blurple LED.
The only reason I am comcered about ppfd and how accurate it really is would be I can pull the same weight with a 600 and a 1k.
I honeslty believer you deminish returns after a point and want to find out what that is. As long as you have high intensity light and even lighting of the canopy I dont see a need. My other issue with COBs and LED for that matter is penatration cannot compare to DE at all.
I see alot of numbers but very few results.

2 pounds in a 3x3 (that's like 900grams per meter^2) with 4 weeks veg ??!?!? I'd like to see some picture of that...
Dont have any currently but ill upload a journal in a week of my 3 x 3 Coco Blue Dream grow. Ben getting just over 2 lbs .
I run scrog and its some high numbers but my genetics play a big part.

I'm in, please show what 2 lbs in a 3x3 looks like. Rounded off, that's like 100g a square foot. I should be learning from you. Thanks.:mrgreen:
No pics currently. Ill upload a journal next week when I flip mu current plants to flower in same conditions. Been getting this weight for a bit now with these genetics.

In the U.K. I weigh 18 stone.

I was taught imperial and metric in American school system as a child. I like metric because it is 10s and decimals. Fractions make my brain hurt. People still use both in U.K. but labeling laws for E.U. insist on metric.

Cheers,

Stone is a unit and thus it makes sense to put after the number.. 18 stone makes sense. 18 weight does not make sense. Saying "800 PPFD" sounds so dumb. "PPFD of 800" makes sense.

Now if you will excuse me... I need to get stoned on some weight.

If you're perpetual, how do you calculate your grams per meter squared. You stated grams per meter squared per day, but that implies you're pulling 800 grams per day it sounds like from your post?
12.5sq ft total, 23 plants occupying the space. That's .54sq ft per plant. 10.76 sq ft per sq meter. 41.4g average harvest per plant currently, at 19.9 per square meter that's 823g/m2, current average of 76.5 days seed to harvest, 10.75g/m2/day.


I'm no expert grower, I see deficiencies, stunt some with over feedings. But autos yield pretty massive considering they can soak in 24/0 lighting. With 482w of cobs per m2, it's only .93g/kwh. Big old sq meter numbers, low electrical efficiency. I can pay an extra $50 in lighting a cycle, I can't add more space. Just need more meds.

So how often do you harvest in your setup?

I try to harvest weekly but whenever they're ready. I do like to plant in pairs though. It's soil only with occasional teas or general organics feedings. Bottom fed wick system filled by a dehumidifier drain hose. Try to max my buds with minimal labor. I've got 2 scheduled to come out next week, so I'll germ a couple more seeds later and actually have 25 plants in here temporarily.


This week's haul, a couple Mephisto White n Bubbly autos. Frosty and sweet.

Make sure you don't weigh wet...
Your quite funny. Have no reason to weight wet. RH at 60. I have my room tuned very well with a commercial pheno.
For me its all about plant numbers and veg. Light plays a part up until a point from what I can tell.

Thats awesome!!!! Cant wait to see it.
Look out for it. Thats my main reason for this thread is I believe after a certain point if you know what your doing more light barley helps.
I find that more plants and veg affect yield more than adding more light. Instead of adding more light than needed at that light to more plants.
I am testing this currently and over the next 6 months ill be testing 600 and 800ppfd over the same conditions at the same time to see if yield is increased and if so by what % and is that % worth it or better served under more plants.

How much ppfd does a DE lamp through out at 36 inches in a 4x6 foot print? Its the Phillips bulb 2100 umol or what ever that is, 1000 watts. Just wondering is all. Not trying to switch the talk off led, i just was wondering.

Platinum LED has the best PAR of any LED on the market inclduing Area 51.

Platinum and Kind LED k5 are by far the best lights."

Bro are you using Pled to achieve those harvests?
