~Newsflash~ there is NO such thing as Cannabis getting "rootbound"

I have seen it over and over again and Im tired of the Myth/rumor being spread on these kinds of forums, namely this one so much.
Cannabis plants raised right indoors will NOT get "root bound" when its roots fill the pot.

Issues that come from growing in small pots are ALWAYS due to plants not getting enough nutrients to grow with.

What happens is this, You start a plant in a small container, it grows just happily. Eventually the roots suck out all of the nutrients in the soil where they have grown to and it becomes deficient in nutrients enough that it stops growing as it once was.

When people transplant a plant such as this, It gives the plant more access to nutrients in that new soil and it continues growing correctly again as it once was.
But this is Not NEEDED and an absolution as most people growing marijuana seem to think.

Leaving the plant in that same small container and increasing the amount of nutrients that you feed it @ that time should be perfectly fine for that plant to be ok and start growing again once you knock out the plants deficiency.

Roots do not need to keep growing the whole time a plant is alive in order for it to live happily and grow. The only thing that is needed for a plant to live happily is all its conditions being met.

To avoid all argument in this thread I will ask this question alone...

"If you believe in a plant being rootbound because its roots have no place to grow into, What makes that plants roots become unefficient enough to stop absorbing nutrients, when they were healthy enough to do that before the nutes in the soil were depleated and all used up?"

Ive been arguing the exact same point as you for a year now to no avail,it seems that after the jorge cervantis video is watched by noobs they believe root bound issues will effect their yeild,then repeat the one foot a month nonsense to others as fact.

No arguement from me,a plants root system need only be large enough to supply the needed nutrients & water to the plant & no larger,something ive found to be true is that plants grown in smaller pots grow faster than those in large oversized pots,i attribute this to increased oxygen to the root mass from increased waterings & feedings.

My plants (3 footers) get watered every other day in one gallon pots & they love it too,i want to water my plants as often as possible to give them fresh oxygen,not let oxygen levels go low or deplete from stagnant water lying in the pot for days on end.

You'll never convince them,it seems impossible to explain that root bound only means more frequent waterings & feedings only.

stays relevant.
I only use large pots for mothers. Always flower in smaller pots... the flowering plants dont produce much of a root system.

Same here on the mothers,how large of pots do you use & whats the longest you've kept a mother,i use 5 gallon pots for mothers & was thinking about going up to & gallon & see if thee is a long term difference.

thanks for putting this up. i'm a new grower and i've read about plants being rootbound from many threads. so this is new info to me.

I would add that in can be helpful to put a layer of hydroton, inert gravel or something of that size/shape at the bottom of the pot. The only problem I run into when packing roots in a small container is slow drainage occasionally towards the end of the cycle. The bottom of the container will still get solid with roots, but the hydroton seems to provide a few more gaps for the water to get through. (vs. only soil-less)

Agreed.

If you are growing trees things are different though, then the more root mass the better, the bigger the root mass the faster you can grow a real tree.

That old rule of thumb of 1 gallon per month is outdated and should be dismissed completely. People are growing 2' plants in 5 gallon containers just because it took them 5 months under crappy lights or because people told them it needed pots so big.

Wow surprised to see such little contest on this thread!
and growtech you say it isnt an issue that comes up often on this board but Ive seen it none the less, and lots of times people believe things even though they not repeat them....


I dont even use large pots for mother plants really....As panhead said I want to water them as often as possible so that they can get the most oxygen possible to their root systems. I normally keep them in 2 gallon bags so I can water them once weekly. And Ive kept them up to 2 years(could have kept her longer but chose to replace her)

I had a 3.5 gal pot. had a sativa strain that veg for 6.5 weeks flower for 12 weeks. It got 4 ft tall. after i chopped it and pulled the plant from the pot. Its roots was all wooven up like a ball of elastics. bearly can shake dirt of it. I wondered why it never showed signs of "root bound" at any point. I watered every 2 days, feed once a week. it look very healthy. after I saw that, it convinced me how hard it is to kill a pot plant via root bound.

Here is an a quick question then. I want to use the smallest pots possible for my grow space. My gro space is 2ft deep, 30" wide, 4ft tall. How many plants can I safely flower and what is a good pot size for each plant?

depending on what kind of lights you were using, this could have been a MUCH bigger plant... if i let a plant veg for 6.5 weeks it would totally overgrow my room... rootbound plants wont DIE, but it will prevent it from getting any bigger... there should be equal parts of the plant above ground and below ground...

bigger containers can grow bigger plants....

This is the thread I have been day dreaming at work all day.

I am growing in 4x4 rockwool. I vegged for 6 weeks. I am in 2 weeks of flower. i have been noticing of course more time in flood for the plants to get as heavy. Also underwatering coming on quick.

Any ideas of what i should do? Basically you mean to tell me I am ok just watering more and they will go fine in 4x4 rw cubes?

I want a few ounces off each one hopefully.

I am lost on this particular case of pot size. Actually they are in turbogarden pots in 4x4 rw cubes with the 1 inch of extra space on each side of the container being filled with mini rw cubes.

Any ideas will be cool. But I do get what you are saying about no root bound. Is their a line to cross.?

Encourage me I am ok and how. Rofl.

yeah, sorta, I was real loaded an basically I answered every question I had as I read the responses over in my head.

So I had no uestions I realised and I had typed out a post, so i um, just sent it anyway, lol.

Good nature. Cheers, drinks all arond. Nice responses. I seriously was stressing pot size at work all day. Never had underwatering a prob like I do.
