General Hydro question/yield question

It's my first time growing so obviously first time growing ebb and flow. My set up is as follows.

40 Gallon reservoir
4x4 Ebb and Flow Flood tray
(16 plants evenly spaced)
1 1000w MH
6x6 Rockwool Medium
Flora Dua A & B nutrients
(at 1/4 Strength)
2 air stones in reservoir

I keep everything very well maintained. Water change every 10 days. Close eye on PH and PPM. Since it was my first time had a couple speed bumps until I got a better PH tester "was using drops" not fun. Everything seems to be coasting. Since I haven't done this and haven't seen a end result, my question is what can I expect (keeping optimum conditions) for the yield? I have heard and read a lot any feed back would be great. Thank you all.

depends on your strain and how long you veg

1000

Expect the worst and hope for the best.

I apologize guys because this question is offtopic but im thinking to start hydro too and im wondering does the airpump and waterpump run 24/7 ??

air pump always on water pump its upto you you could put it on a timer if you want but wouldnt bother really just leave it on

ty for posting

Depends on a lot of different variables. For start you didn't tell us your temps and humidity levels and it doesn't look like you're using co2. If you really want the extra yield use co2, safely please. And every strain, every phenotype will yield differently so after a harvest or two (of the same plant) you should get a feel of how much you can get from your babies. Shoot for 1000 that's the best way to think about it. Good Luck.

temps stay from 67-75 AC controlled. highest it will get at times will be about 80 but not for long. humidity stays between 45 & 50% never lower. and no co2 grow is inside and well that seems a little dangerous. lol strains are og kush and strawberry cough.

I run my air pump 24 hours and the water pump on a timer. I have heard to run the air pump 24 and the water pump on timer not to run water 24 unless its a aeroponic. I am also new to this all so I am not sure if thats true or now.

go back to the list of all the most recent threads in hydroponics/aeroponics and scroll down a few n look for my last thread(it says sour diesel) its my first grow n im useing the gh flora series.a little tweakd tho. check it out. im excited bout my first grow! i think once we get this first one all done the next one will be alot easier n alot bigger!but yea thers no telln what your yeild could be.thers alot of differnt factors. good luck.

well yours looks like a lot there. How much are you expecting from that? Just did a sour d in soil was nice smoke but not nearly as big.

With flood & drain there is no real reason to leave the air stone going at all times,as long as the pump comes on a few times a day your good,its preference.

Infact there is evidence showing that leaving magnetic pumps on 24/7 can create iron fall out so the pump on a timer is a must.

In a 4x4 flood & drain i was pullin approx 2 zips per plant with a 600 watt digi hps.

I also ran 16 per table with large clones taken then allowed to veg for 7 days after bustin roots,then straight into flower.

Like i said this is my first grow too so i honestly dont know for sure.but from what ive seen u lose like 50% of the bud mass once its dry so......if i had to say.....if i cut all the buds off most of my plants right now it would look like 5 or 6 oz's wet.so if u lose 50% while its drying im guessing lik 3 0z'sdry per plant.ill b chopin em down in a couple weeks n ill post more pics n let u know what the word is.pics will b under the same forum.

so will the 1000w make a difference? or no? and mine have been in veg for about a month now. look like little bushes.

You could use co2 but not at very high levels unless you upped the temp a bit, but that sounds pretty good right now. co2 can increase yield by 30% (that's the nimber a lot of articles, and stoners use) you would use a co2 moniter or it would be dangerous. Humidity is good. Good Luck.

most likely anywhere from 6oz to 1lb (with 2lbs being absolutely Pro...)

alot factors into it... but you'll want to switch out to lots of P and K for flowering...

Look up "lucas formula" and you'll understand what I mean...

Ebb and grow dude and use grodan as your meduim, the ebb and flow people grow little plants fast I VEG least a month and flower 10 weeks with co2 I get least 1.75 lb. Per 1000 watt light. Fuck it go big man

Did you read the entire thread before reccomending the op switch gears & adopt a new grow style,the op was looking for specific answers pertaining to his style.

For the op,the 1,000 your running is too large for a 4x4 table & most likely will not give you added weight over my estimate with the 600's i use,i ended up putting my 1,000 watters away in favor of 600's & here's why.

When growing in a fixed area such as your 4x4 table any light thrown past the table is wasted,the larger the light the further the bulb/glass needs to be from the canopy,this causes more light to be cast outside the grow area,it also causes loss of light intensity from increased distance from bulb to canopy.

The issue of wasted light being broadcast past the grow area can be somewhat corrected by reharvesting the lost light using reflective materials or walls,however you cant make up loss of light intensity from the bulb being so far away from the canopy due to heat issues.

When i measured the difference in light intensity between 600 & 1,000 the smaller light gave far better penetration with more lumens to all areas from canopy to net pot,this is because the smaller light can be ran a half inch from the canopy where the big boy needs to have space between the glass & canopy.

Since switching out the 1,000's i was running in favor of all 600's my yeilds increased about 10%,maybe a bit more.
