under yielding

[dlu]

hey all i have 24 lavender (hydro) under 4-1k watt,exhaust intake, grown under rockwool. ph-ed at 5.8 and water temp is 62 degrees, ppm is no more then 1200, no light leak. and im under 1.5lb per harvest can someone tell me what am i doing wrong?

I can't speak for your grow but I tried Lavender 3 times then threw the shit away. Never produced shit for me.

Good luck.

i put that many girls under 400 watts
think about 20 girls per light
smaller pots, more girls if necessary
here's my setup with 800watts I'll get over a pound http://www.icmag.com/ic/showthread.php?t=194145

don't know what's in your equipment setup but I use:
co2
dehumidifier
stadium style setup

look around others setups to get ideas...

Tell us more about your set-up. Pics could help alot.

1. What style of hydro is your system? Growing in rockwool, not under Are you drip, ebb and flow etc.
2. How long are you vegging?
3. Are you topping, any kind of training?
4. What does your canopy look like, is light hitting the floor?

Consider a strain change but unless its absolute super garbage, 1.5# for 4k is way under producing for any strain I've run. I'd consider dropping everything but the GH B,M,G and some epsom salts.

 

[supermanlives]

well that is the lowest yield i ever heard of using 4k. new strain, longer veg or more plants

 

[Shcrews]

lavendar is a low yielder btw

 

[stoney917]

sounds like the cut u got sux bro 1.5lbs for 4k sumthin is deff wrong. 24plants 4k is alot of work for a newb aswell maybe try and run less plants under 1 k and perfect them then add the 3 k once dialed in. my suggestion would be run somthin else

 

[qbert]

without pics at least its hard to say, but crappy strain certainly seems plausible, and with others' comments about lavendar we have a winner ... er, loser.

For starters, the plant is not "under yielding". It is you that is the prob.

Maybe you should grow on top rockwool instead of under it...

That's way too long a list to feed, cut it down.

If ur using Hugo blocks, condition them better/for longer

Have you searched for pests? No webs? Root aphids?

You r making a huge, likely simple mistake.

 

[PuReKnOwLeDgE]

read my threads, I grow in 24 site hydro, 4 K, and 1.5#s isnt in my vocabulary. I use an EASY feed schedule, 2 bottles.

 

[HydroJen]

I just pulled my first rockwool harvest. Pulled 10# from 6k. Here's my recipe:
3 mL/gal cal/mg
4 mL/gal gh micro
12 mL/gal gh bloom

After day 40 i drop the first two and feed bloom only. Im still tweaking it, but the idea is that less is more.

well not rrue i would say - i had plants that didnt yield shit beside plants that outyielded everything ive ever had ...

my bet would be:
- new strain: northern lights #5, ak47 ... bulletproof
- at least 16plants per lamp
- if less vertical bulb

but picutres would help very much! i guess you have shitty plants but maybe you are making mistakes - keep your head up and make a report next time - ppl will help you and tell you your mistakes!

i mean i get a pound from one 600

Genius idea! Tell the failingnewb to invest in a trickier set up!
Also, brew your own Tea at home and create your own genetics from seed. That should help ya get started!

well i dont know what is trickier about more plants or vertical bulb ...
just need to do some reading ...

I do, and it is not the answer to .37lb/k

Turning your bulb the wrong way will not make your buds bigger of plants healthier.

 

[Shcrews]

vertical bulb is not the wrong way, read the vertical forum to improve your GPW!

No thanks. I prefer quality to quantity. More lumens per bud for me.

 

[alwaystoned_1]

lol hydrojen you will get more lumen use from a vertical bulb than using a reflector

 

[Green lung]

Turning the bulb verically aint going to help a guy who only gets 1.5#..

The bulb ain't his problem.


Get It

To all that grow using the bare bulb vertical setup.....Hello, and thank you for seeing the light!!!

To those whom doubt the bare bulb........

I run 4 600w vertical setups and Im sick of seeing nay-sayers, telling people that vertical setups arent better. If you want to say your horizontal setup is better than a vertical, then please show me your results. I switched from 4 horizontal setups to 4 vertical setups.

I am confident i can get a pound from each of my 600w bulbs with 8 plants around each. thats like .25gpw more than what i got horizontally.

The only thing i changed was the fan positioning, the bulb positioning, and the plant positioning, all nutes and watering schedules are the same.

Light is NOT lost or multiplied thru reflection, but heat WILL multiply thru reflection. Lumens output is rated for the whole bulb, NOT just one half, 8 plants around a 600 watt bare bulb will get the same amount of light as 4 plants under a 600 watt bulb with a reflector. You can fit more plants around an entire bulb than under half of it, there isnt as much heat, your not as limited in height, less equipment to purchase, less weight to hang, and THE SAME AMOUNT OF LIGHT AS A HORIZONTAL SETUP!!!!

THE KEY TO VERTICAL IS MORE SPACE......WHICH MEANS MORE BUD!!!!

I had 9 plants in 3 gallon containers, under a horizontal 600w. I could grow them maximum of 2 feet tall because of the tent height, reflector size, and heat problems. I pulled about a half pound dry from this.....

.....I can now grow 8 plants in 3 gallon pots, around a vertical 600w. I can grow them maximum 5 feet tall, depends on the strain, without growing into the duct fan. I dont have any issues with heat now, dont need a/c or co2, so less expenses again. I can pull about a pound dry from this.......

.......simple.....5'x5'x6.5' tent is 25 sq.ft. that a horizontal setup will illuminate, and about 75 sq.ft. that a bare bulb can illuminate......

......Plants grow UPWARDS, the top of your plants see the light with a reflector. When you look at your plants from the top you can see less buds and sites than if you were looking from the side. So if YOU can see more bud and sites from the side....SO CAN YOUR BULB!!!!!! Dont diss the vertical setup until you have personal experience with it.

VERTICAL IS EVEN BETTER FOR STEALTH TOO!!!!

For those with small cabinets like for example; 3'x3'x3' you can grow 4 plants in 3 gallon pots, up to 2' tall maximum, around a single 250w bare bulb. With my nutes and care i could confidently expect over a quarter pound with this setup, of course ventilation is vital in a 3'x3'x3' box........I think ill build a small 250w 3x3x3 vert to show what it can do compared to a hotter, more expensive, space consuming horizontal 400w.

I didnt mention it, but yes im only talking about hps bulbs here.


Feel free to argue but nature is always right!! The sun doesnt have a reflector because the lumens output would be the same, it would only get hotter......why fix what isnt broken???? Why pay to cool your room when you dont have to???? Why grow 3 foot tall plants in a 6 foot tall space????

My next grow will show the potential of one 600w bare bulb with screen training.....I will be using MARLO's IVSCROG Setup.....sorry for naming it for you Marlo.... change it if you want...lol. Check out Marlo's grows, IVSCROG with dual 400w bare bulbs.


If you read all this and dont understand what im saying........feel free to ask......feel free to bash me too. Just dont tell me you get a pound from a 100w incandescent bulb.....or any other BS.
