Low yields, need some help.

[topfuel29]

So i have a 400w Hps for flowering and i flower at least 5 plants in this light with a 3x3x5 growroom.
My yield per plant is just 15 grams, i had one Bubblelicious from Nirvana Seeds with 30gr dry in the final but thats it.
I just want to learn how to get 2 ounces per plant or something like that...
I veg for about 1 and a half month,i top every girl to achieve more tops,my temps are 82F,i use All Mix soil by biobizz, with organic nutrients like Bio Bloom, Bio Grow,Top Max,Bio Heaven...
I put my plants in flower when they have 12 inches-15 inches.
I got a fan circulating the air inside the growroom and a 107 m3/h intake and outake 190 m3/h.
400w hps with an adjust a wings reflector.

Your flowering temp are a little high.
you said you veg for 6weeks but your plants were only 12-15inches high. They should if been bigger with that amount of time. Mine grow 36inches in 8 weeks. Your bulb is new? Name brand?
how many gallon container? Did you have problems in veg w/ nutrient deficiencies? Are you using city water or well water? Are you making sure not to over water? I believe your problems start right in your veg and carry over to the flowering.

IMO you would be better served honing your skills with your current setup rather than adding a shit ton of other variables to take control of.

The journal in my signature is a hydro journal documenting everything from res testing and adjusting to environmental aspects etc

With your current 400w if everything is dialed in you should be able to achieve 300-500g from a harvest so don't listen to those who try to convince you to change everything or add more light etc.

Learn your craft, read the plants, control environmental variables.

These alone will bring you good yields.

Feeling what you are saying! Thank you

I can't imagine having a space that small with 5 plants. Must be hard to get good airflow and light penetration. If it were my space I would start with only 2 plants. LST them a bit when they are small so you have 6 to 8 vertical branches and veg them until they are about 2 feet tall. Keep the air moving and the light about 6 -8 inches above the canopy. Water by weight and use minimal nutes til you figure out what you're doing wrong.. I've made every mistake you can think of with growing and my yields have never been as low as you describe..

They are very low i know, just want to learn what im doing wrong...

 

[Medicatetoday]

My point that I'm making is that his setup should be fine.

Is a pound 16oz in the USA? I pull that from 400w using 4plants.

I'm not gonna get into a pissing contest with you.

I've done hydro. Then the police came and took it away.

15g per plant under 400w with soil means that there is something wrong. Not that he needs to go out and get a hydro system.


With a simple change of a few things such as temps, nute mixes and possibly switching to a soiless medium could help him bump up his yields.


Original poster - what is your environment like?
Are your temps under control?
Do you have enough air exchange?
Are your plants severely yellow at harvest?
Do you get funny colours on your leaves during flowering? Such as browns/purples/yellows?



J

Yes they are yellow ate harvest,In some the leafs turn purple in the end of flowering.
Some leafs get yellow and die,i think sometimes the heat rise up a bit in the growroom,can you tell me how can i control it better?

 

[growone]

probably one of the more useful things to do is have a grow log for the next grow
pictures versus words kind of thing

 

[Medicatetoday]

Are you growing bagseed?

Pick a method and stick with it and dial it in. Soil or hydro, either is fine and has pros/cons. You indicated an interest in hydro, and you can get into it simple and cheap with hempy buckets. That growing style will feel very similar to soil growing, but you should get faster veg and bigger yield than soil.

The thing with hydro is there is pretty much a mandatory up-front investment for a ph pen and ppm pen. But other than that it's not hard. Doing things like training for scrog and super cropping are more advanced and I would suggest leaving them alone for the most part and just learning how to grow some good bud before you experiment too much with training or more advanced setups. Topping and FIM are easy and will increase yield, but also increase your veg time.

The ideal setup also depends on if you are growing for personal stash or need quantity for selling or whatever.

Appreciate the comment!
Im growing good strains,the quality is very very good! Lots of trichomes , good taste , good smell,good appeal...What i do want to change is just the quantity.

You were arrested?

How they found out your grow?

 

[Medicatetoday]

Maybe...
Just....Veg them longer...
Maybe, They do not have a complete root complex with a short veg period...
Are you harvesting them when you see first signs of amber trics? [first signs!!!]
If you see no amber, then plants maybe could have grown bigger...

20/30% Amber is when i harvest

Sunmaster Bulb,yes its new.
3 gallon and 4.
I had some Potassium deficiency i think ,some marks in ball shape.
Distilled water.
Yes i dont over water,that i know...

No pissing match just a disagreement, but youre saying 15grams per plant under 400 is something wrong, thats not true at all, if he had 1 plant then yes, but why would you think hes gonna have more yield with more plants, its the lights, more lights more yield, more plants same light less yield!!! thats my point as he asked how to increase yield, so i said get some lights and go hydro, and i WILL defend hydro when people say its so much work, BULLSHIT, its easier than soil, soil is a buncha mixturs of all kinds of different things plus the main soil has crap in it already,hydro you can get 3 bottles and some water, mix them up to whats on the bottle, set your ph and bam, watch em grow, and way bigger way faster!!!!!

Sounds like your on the rigt track... if something was going wrong you would notice it an be nervous. When i did soil my main issue was i used ONLY soil. Mix with something to air out the soil. My soil ended up being crazy compact... roots need oxygen to grow! This is why hydro is lovely.

I use 400w SYLVANIA GROLUX I only grow 4 plants, they never reach above 2.5ft I get 100g per plant sometimes more.

Yet its his light???

 

[hydrocropper420]

all im getting at is that it dont matter how many plants you got, you should be able to get a gram a watt, 1 plant or 25,either 1 plant with huge buds or 25 with tiny popcorn buds, so with all the soils and nutes and ph being on track with any grow, LIGHTS are in the yield size, all the right soils and nutes will give good buds but without lights its gonna be a light bag!!!!

The simple answer is lower your heat to around 75f and keep them green for as long as you can.

Use veg nutes the whole way through if you have to.

Exactly. So he should be able to yield 400g when everything is dialed in.

You're telling him to change his light and growing method, which could cost him a few hundred bucks when he really needs to address what's happening in his current setup.

You are implying that regardless of what he does he won't get that yield unless he changes lights and switches to hydro.

Which just isn't the case.

I agree with you that hydro can be easy but if you think its a simple as follow the nute bottles then you are a little deluded.

Monitoring EC ppm TDS in hydro is something new growers should do to track swings in strength and pH to gauge how plants are feeding.

I do also understand the SOG technique.

However with his current space and the temps he's getting using 400w he needs to get things cooler.

His leaves are dying with yellows and purples by harvest time.

But I guess that's because he's not in hydro?


I really have no clue why people don't just help those that need it based on their current setups. There are always some that expect people to change.

I've used 600w, 400w, coco, soil, hydro, it really doesn't matter yields can be achieved regardless of what your using.

Yes you are right there is no reason why people cannot achieve 1g/w but there certain things to ascertain and then address before full system changes are recommended.



Final post in this thread for me otherwise I'm just going to end up arguing through it.

It has to be your temps and/or nutrients. I grow in a 2x3x5 w/ a 400w or a 600w (depending on the plants/canopy/time of year/blah blah blah). My preferred method is obviously DWC just because I find that it is the easiest medium to control.

Now, with that being said I have 2 grows under my belt where I used organics/soil next to my DWC systems. I stopped doing it due to bug problems, but that is a different story. Anyways, just using the 1-part flora(It was given to me) + some calmag I was able to pull 1.5-2 oz per plant using Nirvana's Blackjack, Bubblicious, and Aurora Indica with very little effort. I've grown all different types of plants in my very limited space using various methods, so anything is possible. I typically only flower 2-3 plants at a time in DWC, usually in the 3-5oz/each range. Normally grown from seed w/ around 6wks veg under low power CFLS and 1 week under HID... then however many weeks the particular strain needs for flower.

If I were you, I'd 1.)clean my grow area the best that I could (I've had some weird funk get on the walls of my tent that killed plants. It looked like a film.) and find a way to cool that bitch down the best you can. If you are strapped for cash and want to try different nutes, go the Lucas Formula route - it's the cheapest up-front cost, and works like a charm. Do you have any pictures of the plants while they were growing? I'm sorry if this has been said/asked. I didn't read every comment in the thread. If this stuff has been addressed, disregard that. haha

 

[hydrocropper420]

ill agree with you on your take on his grow and im impling for future to get more yield, i think he might have to take what he gets off this one, but DELUDED, really??? im a very basic hydro grower and absolutely will not listen to someone try to discourage other people saying they need all this monitor stuff, its nice for a ''big show'' but for a small grow room, a damn ph tester and a regular thermometer is all you need with the nutes, thats all i have is 3 bottle, ph balance of 5.6-5.9 and mix the nutes exactly to what the bottle says and thats it, let her grow, i have proof of the results, check out my grow, but like i said, you are right and im not arguing about his present grow!!!

It's not good to leave out a PPM meter. It is very essential to any setup.



Also, to the OP - To lower my temps, I cut a 6in hole in the top of my tent to feed ducting to a 440cfm fan + carbon filter outside of the tent. The fan sucks the air through a Cool-Tube, out of the top of the tent and out through the carbon filter into the closet everything sits in. I have to keep the ambient room temps outside of the tent 8-12 degrees cooler than my desired temps inside the tent. Hopefully that helps give you an idea of what kind of heat to expect.

ps, I measure heat 4 inches above the canopy if possible, at the canopy if not.

 

[hydrocropper420]

Right one thing i left out DER, but thats it and hydro is very doable

Hydro is my preferred method. It's cleaner and easier to maintain. Not to mention cheaper (where I'm located), however this may not be the case for the OP. You don't know if he has money for air pump, stones, hose, nutes, buckets, netpots, hydrotron, peatpellets/rockwool/etc. I started in soil because it was cheap start-up and I had soil pots that would fit where DWC buckets would not. lol Point is - he doesn't necessarily need to change his method. There are cheaper alternatives to diagnose the problem than going full hydro (assuming he has zero equipment for hydro).
