Two plants in one pot?

You can use one pot for two plants but preferably, one plant per pot is best.

Not everything is black and white, and this site has no shortage of mavens that have me shaking my head at times. Luckily this site has members like Filthy fletch and others that really know their stuff, and they genuinely try to help their fellow Rollit members.. Which is all I ever try to do. I don't berate people for being new, even though I'm new here.
Here's an example regarding misinformation, this Rollit member has 1000+ posts and high rep & pretty much blasted me and called me a noob for giving this new user ACCURATE info. (notice he never came back to apologize for being an moron, it's ok as I don't hold a grudge)

Post count and sometimes REP has zip to do with what a person knows. That member Pinksensa has no clue that I know a fair amount about horticulture. I've studied Hydroponics formally and by experience on several continents where I learned a great deal in the field. I may have 20 posts, but I don't think I'm a noob. I've probably been growing since PinkSensa and other in that thread were most likely in diapers. He still gives good advise, despite his inability to read the problem an inexperienced person may have, and the advise given to the new inexperienced person.

Anyway, lets get back to this question about one pot per plant.

One of the reasons it's not advised is in the event that one plant is a female and the other is a male, when you pull the intertwined roots to remove the male, it puts some stress on the remaining plant, plus remaining root rot issues....

With that said, with Ebb and Flow or soil grows with traditional non net pots, (i'm referring to normal square hydro pots and normal soil pots)

I try to use one pot per plant. At times where I have more plants than pots, I'll use one pot and two plants. BUT, I take prevenative measures. I simply take a piece of plexiglass and cut it to shape with a dremel, I cut it so that it serves as a divider inside the pot, this method keeps most all of the plants roots seperated, if I have to uproot one plant, it's less apt to stress the remaining plant in the pot, and I'm able to remove 99% of the roots so root rot isn't much of an issue. I then remove the divider.

(I've even had success with with more than two plants per pot, but I only do this with clones that I know are female, but 'quartering' the pots and putting in the plexiglass is a bit more difficult, its much easier to just stick to one pot per plant and use smaller pots if necessary.)

With Aero 'net' type pots this isn't really feasable as the roots suspend and can intertwine and a divider is not as easy to implement. For Aeroponics, one cup or pot per plant is best, you could always use smaller pots and keep the ratio 1 to 1

Anyway, thats all the noob advise I can give.

The answer to the original post is YES... THEY WILL GROW.
Unfortunately the plants will compete for everything as they essentially try and kill one another. If you play your cards right and DO NOT PRUNE, you could get two different strains to taste, but IT ISN'T WORTH THE EFFORT FOR A SINGLE STRAIN.

Cheers for all the help guys, im going to give it a go with a divide down the center. Hopefully all will be ok. My next hurdle is finding a way to drain this large container..

Bit worried about my seeds germinating aswell, its been 6 days now and nothing

Hey Gigglepimpster,

Something I didn't mention is a REALLY easy way of making the divider. Just go to Wal Mart or a supermarket and buy plastic notebook dividers. (or any other type of riggid plastic, black ones are best) They are about half a millimeter thick, or roughly as thick as a couple sheets of paper. You can make the pot divider out of the thin sheets of plastic. By using a thin plastic divider, you can cut it with scissors, with plexiglass you need to score it, then make the cut with a dremmel or brute force after scorring.
The plexiglass is better because sometimes crap and salts buildup gets stuck in between the sheets of plastic , but you can use plastic notebook dividers in a pinch. If you go the plastic notebook divider route, double up the plastic using two sheets per divider to make it more ridged, place it in your pot and your all set for two plants. Last tip is this, if you use notebook plastic dividers and your able to, seal all four sides with silicone, this will elimate the problems of crap and salts building up between the layers. Any ridged plastic can be used as a divider for the pot, just use your imagination and I'm sure you'll figure out something creative. Hell, you could even cannibalize one of the pots, cut out the four sides of one pot at the corners, and you'll have 4 perfectly sized dividers, the Hydroton rocks or whatever medium your using will hold it into place.



PS, Cyks,

Are you talking about hydroponics in regard to the plants fighting over nutes and such? I've never seen two plants in one pot kill one another. Never seen them suffer any ill effects either, with or without dividers. Could you show me where you got this data?

10 seeds per 1-gallon plant pot. Then you'll have plenty of root space.

Are there even any peer reviewed white papers written on this subject,ive searched high & low & i cant find any real information one way or the other.

Seems that alot of stuff thats perpetuated about growing is unsubstanciated myths,passed along from person to person,this 2 plant one pot deal is a perfect example,people jump straight in telling others not to do it, infact warning others not to do it,without giving any reasoning of personal experience why they so strongly warn against doing such a thing.

Plus Reputation for that because its very true,sometimes some of the best things turn up from thinking outside the box.

Excellent, cheers mate, i was beginning to wonder what i would need to use as a divider, as thin wood etc could begin to rot. I'm going to look into the plastic dividers tomorrow, should save me a lot of time, and failure, Cheers!

I'd read any white papers if I came across that kind of info. Obviously one plant per pot is always ideal if possible, for lots of valid reasons, just I think that death by the sibling due to being in the same container is a bit of a stretch. Maybe if your growing baby masked boobies, never heard of hydroponic or properly watered soil siblicide via a choking root ball in growing our favorite herb, heard about masked boobie chicks committing siblicide tho...

Barney the boobie says; "Use a container divider if your forced to use one pot for two plants!"




Barneys a noob here too.

Them damm noobs

Everybody knows post count is king

man ive used cardboard inside of a white garbage bag for a divider before. just cut down the cardboard to the correct size duct tape the sharp ends and put inside a garbage bag. fold the over lapping part of the bag around the cardboard so the water cannot get in. dont duct tape the outside of the bag. just make sure its only for a one time use. peace.
