Can you plant multiple weed seeds in one pot

Can i put 2 seeds in 1 pot?

Wondering if I can plant 2 auto’s in 1 five gallon container? Would it really ‘kill’ both plants? It’s my only option or I throw away the 2 seeds that I put to germinate. Can’t buy soil anymore at this time of year in my city.

Yes you can and it won’t kill the plants. Assuming it’s a fast variety it will be fine but, it will get crowded as they grow into each other’s canopy. Personally I would run single autos in a 2 gallon. 5 is a bit more than you need for the fast ones. Up to 13 weeks. But have done 2 in a 3 gallon. Not optimum tho.

the two I did previous were in 4 gallons each. I planned to do 4 now and 2 are planted in 4 gallons each again..but since I couldn’t get soil, the two germinating have nowhere to go now. I already planted one of them in the same 4 gallon as the other one is in. It hasn’t popped out of the soil..dug carefully, cant find it, tap root wasn’t visible when I planted 2 nights ago but seed was open slightly. As for the other container, that seed has popped through the soil..I was thinking replanting it in a 5 gallon with the last germinating seed in same container. Is it better to put a divider maybe halfway down the container so roots wouldn’t grow into each other as much?

These were the roots on last 2 auto’s alone in the 4 gallon. I did underfeed them as well in flowering. my first grow.

plant them both on the opposite outside edges of each other in the bucket and as they grow kinda put a stick in between them so they train to grow away form each other or tie em they wont get in each others way

Do you only have room for a five gallon container? The best things you could do are get a larger pot. Square if possible, then plant in either corners but not right against the side. Ive seen whole warehouses done sog this way in square buckets. Nice yield.
Also try and train the plants so theyre not getting into each others business. You may have problems if ones a short one foot super cola, and one sqirts up five feet. Good luck.

it is never optimal to have two root systems confined in a container. roots will fight for dominance, like kudzu strangling shade trees.

and they may even communicate, almost always ends up being.

one boy, and one girl.

I had room for 4 four gallon containers. I only have 2 filled. I have about 6 litres of coco/soil left..so I can empty one 4 gallon into the 5 so I can put the 2 seeds in there, each maybe 2 inches from edge on opposite sides? The seed in there now is ‘easy bud’ from royal queen seeds..its not supposed to be big at all.

If you have a “Family Dollar” Store or equivalent close by, buy a 20gal square plastic tote for 5bucks. This will give you more surface area for 2 mature plants with 5gal bucket of substrate if you just have to plant in same container plus you have a 50/50 chance 1 will be male unless Feminized.

I can leave the 1 seed in each..i was just wondering with the options I have..what’s better..will it be better to put the 2 seeds in the same 4 gallon or throw them away and just leave the 1 each that are in there now? As for throwing auto’s away.
I grew the first 2 auto’s..took 60 days, made mistakes with feeding (improper fert), the two yielded maybe an ounce combined (used I think a dozen 23 watt cfl’s). Last one I grew a regular one..vegged 45 days..flowered 10 weeks with 14 same wattage cfl’s (Plant was healthy throughout), and curing now, looks like about 1.5 oz. So I thought with better care..the 4 auto’s should give me 3 oz’s in just over 2 months..so I chose that route.

seeds are feminized auto. Also, again..i cant get anything bigger..i only have max 1.5 gallons of medium left. its why my only option is switching the 4 gallon im using now and replant into a 5 gallon.

Well then, yes you can plant 2 seeds in 1 container. Main thing is get them up and then decide what to do. Maybe you can locate more coco etc. before the extra seeds get a foothold.

I can get more coco, but only on Monday. Seed’s taproot is already close to a knuckle long in the napkin..not sure it can wait till Monday. Maybe better just to plant for now in what I have and transplant in 2 days? Just wasn’t sure which is better. to have 2 in one pot for the duration of a grow, or shock an auto with an early transplant instead.

Ive been watching these square pots for a while but am not growing anything at the moment. I would say better is to have smaller pots for each plant. Me, I’m all about 12/12 from seed tho so small and fast to harvest is my goal. It works. In my opinion most autos don’t need 5 gallons. Again small and fast is my goal so, I pick those types of genes to work with.

I had 2 sativa doms in a 3 gallon once and they actually did get to 4.5-5 feet tall but very lanky like a sativa. It worked out ok. Not optimum tho.

after a bit of chaos..they’re all separated now..the ‘lost’ seed grew out today right next to the one I planted last night lol. Will be looking for soil tmr to fill the 2 other 4 gallons up. Don’t want to do it in strictly coco as that will cause issues during watering. I’ll have to water 2 of them more often..with different ph, different feed slightly..i’ll try to make the same mixture as the other 2 have. Surely I can get 15 litres of pro-mix somewhere in the city.

Q&A: How Many Cannabis Seeds Per Pot?

How many cannabis seeds per pot? We get asked this a LOT.

It’s an understandable question with a simple answer:

It’s always one per pot.​

If you want to know why you only plant one seed per pot, then keep reading.

If not, get out there any plants some damn seeds already!

How Many Cannabis Seeds Per Pot?

It’s still just one. There are a list of things that can go wrong if you try to plant more than one. While theoretically, planting multiple plants per pot makes sense.

You can save money on planters, soil and marijuana nutrients. But, in practice, there is just too much that can go wrong.

Multiple Seeds in One Pot

Unless your planter is HUGE, your plants are going to be fighting over nutrients and root space.

It’s not the same as planting cannabis in an in-ground garden where they can stretch their roots.

In a planter your space is already limited, and placing more than one plant in a pot can stunt both plants growth. Another problem you’ll run into is sexing.

Unless you’re buying feminized seeds from a reputable seed bank, you’re playing a game of hit or miss.

If you have a planter with two plants and one turns out to be a male you’re in a real bind. You can kill off the male, sure.

But the two plants roots might be bound to the females which will kill her too.

Exceptions to the Rule: Breeding

There is one time that putting two cannabis plants in one pot might make sense:

Breeding.

If you are low on space, you might consider putting a male clone and a female cannabis clone in the same pot.

Since you won’t have to worry about separating the plants, this could work.

You’re also not so worried about the bud you’ll get from either the male plant (which is none) or the pollinated female, so you don’t need huge plants.

This makes the fight for root space meaningless.

Let them Sprout Before you Plant

Before you’re transplanting your cannabis to their final container, you should be germinating them.

Germinating is done one seed at a time, so if you’re wanting to plant more than one seed thinking that some won’t take, don’t.

Germinated seeds with sprouted roots will sprout into the seedling stage more often than not.

If you’re not sure how to germinate, be sure to check out our guide on germinating cannabis seeds. And if the issue is money, plant your seeds in grow bags.

They are a lot more cost effective compared to clay or plastic pots.

Another cheap alternative is 5-gallon paint buckets—that have never had paint in them of course. So, unless you plan on breeding two plants, stick with just one seed per pot.

Do you know of any more situations that would require more than one cannabis seed per pot?

How Many Cannabis Seeds Per Pot?

If you have ever wondered how many cannabis seeds per pot, look no further. One seed is all it takes to grow one plant so even if you see plants that look like as if they were bushes it is all just one seed. Regardless of the apparent size of the plant, all growers know that only one cannabis seeds per pot is required.

So you know how many cannabis seeds per pot, but you want to know what will happen anyway?

If you use more than one or many cannabis seeds in a pot, the cannabis plants will begin to compete against each other for nutrients, so the smallest cannabis plants (which sometimes may be the best phenotypes.) will get wiped out by the bigger cannabis plants.

If you are growing from regular cannabis seeds they could also cross-pollinate resulting in buds with cannabis seeds in them. It sounds simple enough but if the buds have seeds inside them, the potency of the strain can be reduced up to 30%. Each cannabis seed is a plant and they need their own space to grow and thrive, as well as to produce bigger and better buds. Remember that more than one cannabis seed per pot is too many.
