Low yields, need some help.

[Medicatetoday]

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...
If you can help me i appreciate that! :)

Need a little more info to help ya man. 1st timer? Experienced? Dirt r Hydro? How long did you veg them? What nutrients did you use, if any? Help us help ya!

5 ft. in height is not helping, anything....6/8 ft. would be better for big plants. IMO

Im in my 3rd grow.
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.

Just from the info you gave, you need to veg longer and top more trim bottom branches off or SROG. Because of the 5 foot high room you need bushmaster bad. It keeps them from gaining height and so they bush out and go straight to maturity. Maybe get your temp down just a bit.

Doing very well you should get .5 grams per watt. 200 grams. more than that is excellence.
Patients in the veg time will pay off. I started very similar to you and went to hydro to find my way to what I needed. I do very well now and am finding my way to excelence.

I would also advise adding some CO2 to your setup with the temps and you may have good effects

That sounds like a great set-up. I've used Biobizz before, good results.

15 gm a plant is not good. I've done a lot of grows with 400 watt. Over 400 grams is normal. Average number of plants = nine. So an average of 50 gm/plant. I use 3 gallon plastic grow bags with rich organic medium, home mixed. pH of well water 7.2-7.9. Water is drawn into a 5 gallon tote (at this time of year the temp is low 50ºs), Correct pH to 6.2-6.5. Run airstones for 24 hours. Temp goes up to 65º - 68º. Check pH, water the plants.
I do veg for eight weeks or even more. But with 5' height six weeks sounds good for you. I crop at the third and six nodes. Like when they are tiny. I trim all the lower growth but I don't worry about height. LST would word great for you too.

Doing Lst right now :thumbsup:
Thank you for the help!

You need genetics, that match you and you style.

[polishpollack]

I suspect you're adjusting your pH to low. Can you explain what you mean by "rich organic medium?"

[Shovelhandle]

Pollack, I think you're misunderstanding the posts. I'm (Shovelhandle) using the rich, organic medium and adjusting the pH. I'm not having any yield problems, Medicate today does. I adjust the pH that low because it will go back up a little during the 24 hour warm-up. As long as it finishes between 6.3 and 6.7 I'll leave it alone.

[Medicatetoday]

Thats what Shovelhandle said...

[polishpollack]

oops, my bad. didn't realize it was a quote. I've never heard of biobizz except now. Medicatetoday, did you get the answer you were looking for? You should be able to get two oz or more easily from 5 feet. If you didn't get the answer you wanted, can you explain your grow better?

Im doing Lst and waiting more 15 days in veg,my older plant in veg is in the veg room for like 1 month and a half...
Im gonna try to control more the heat and the temperature in the flowering room.
Right now i have one Aurora Indica (topped) and one Ak 47 (Lst) in the flowering room ,day 30 for both,if you want to know i notice a big difference from my first plants with the low yields.
