Does pot size really matter?

if your growing in soil style pot culture (including soiless media pot culture) then yes its very important. The soil acts as a reservoir to hold nutrients and water. The soil also acts a media for microbes that make organics or fertilizers (like Ureas) to break down to the plant usable forms. If you are root bound then you do not have an adequate reservoir or media.

If your media has adequate drainage you can compensate with frequent watering with water soluble fertilizers, but then why are you growing in soil and not hydroponically?

Ideally Repot just before they become root bound.

Sorry double posted by mistake.

I plant straight to the five gallons just to avoid the extra step.

But a tray of seedlings in 4" inch pots can be lit with the same lighting as one five gallon pot ...

and you will need to flower them strieght from clone with no veg then still only yield a 1/2 per plant but if you have 100 of them it sounds good aside fom the felony

I did not mean to grow a 100 in 4" inch pots. Thats idiotic. I meant to grow in 4" pots until they were big enough for bigger pots. Takes a lot less space and light. The plants actually seem to grow better in pots that are not extremely oversized.

you want the plant to be root bound when you up pot. When the plant is rootbound it is nearing the max that it can take in, so it needs a biiger pot ( more dirt). But you would like to get it root bound about a week before harvest in a perfect world. Well i would anyway.. Rootbound showes good growth and that the plant is feeding well but it also shows its time to up pot, or it will stop growing and feeding well.

wrong......

Thats Sea of green!


seedling clone room/cabinet under t5 floro's, veg under 400, flower under 600 pound pound!

yes that would be SOG, idiotic in states with a plant limit.

Since I've shared my thoughts on pot sizes and how they play a part, going to toss this in as well - pot size also plays a part, especially if you're rolling something like this:

if u growing outside really use bigger pots cause u plan on getting from a pound to a ponud n half when finish so yes use bigger pots outside but when inside when floweing use from a 3 gallon to a five gallon wide depending on what u want cause when flowing the plant double to triplen size so u groing to need the extra space i just cut my whitw widow 4 days ago n i use a 4 gallon pot n the roots was still root bound i mean the whole pot was still filled with nothing but roots from top to bottom so extra space is really good to have when growing
