do i have a 5 gallon pot or 6,7 the measurments of my pots are 13½in diameter and 14½in in height
One US gallon is 0.133681 cubic feet = 231 cubic inches. Your pot is 1.125' diameter (radius is half that, or 0.5625') and 1.208' tall. The volume of a cylinder is pi (3.141592) times the radius squared, times the height. So your pot volume is pi * (0.5625^2) * 1.208 = 1.201 cubic feet. This is 1.201 / 0.133681 = 8.98 U.S. gallons. You get the same number using cubic inches of course (pi * 6.75^2 * 14.5 = 2075.5 cubic inches = 2075.5 / 231 = 8.98 U.S. gallons).do i have a 5 gallon pot or 6,7 the measurments of my pots are 13½in diameter and 14½in in height
I did the exact same math, got the exact same answer, but didn't believe my result. So a 1 cubic foot box can hold 7.479 gallons? That doesn't seem right.One US gallon is 0.133681 cubic feet = 231 cubic inches. Your pot is 1.125' diameter (radius is half that, or 0.5625') and 1.208' tall.

It's right. A 6.14" per side cube (cube root of 231) holds a gallon, so a 12" per side cube would hold about 8 times as much (2^3). Grab one of those plastic one gallon water jugs from the supermarket and it measures roughly 6" x 6" x 7". For the original poster, you could grow a monster plant in a 9 gallon pot and need a lot of soil mix, water, space, etc. Unless you're doing that it is a lot easier to handle 3-5 gallon pots for an indoor grow.I did the exact same math, got the exact same answer, but didn't believe my result.

Yep, you are correct.It's right. A 6.14" per side cube (cube root of 231) holds a gallon, so a 12" per side cube would hold about 8 times as much (2^3).

Size is up to you, you decide whe3n to put it in 12-12, and they grow 1-3 feet during flowering depending on strain.so how big of a p[lant do u guys think i can grow in my pot right now my plant is currentl 2ft and 1 inch tall its 1m 3 weeks and 2 days old
