Paper cups, not even the waxed ones didn't hold up for me.
plastic bathroom, styro, or yogurt cups,not yoplait, they are too tough to get plants out of.

So are those tiny 2 oz cups. Everything is tough to get plants out of if there isn't a root system unless I can use a spatula or spoon.

It seems to go faster if you keep what your doing that session fairly uniform in size. Those 4 inch plastic pots I save and reuse. If Bluestone can ship a good-sized plant in them, they should work for planting seeds but need to be kept moist by covering or putting in a larger container with a lid.

See the plastic cup thread for more ideas.

I use take out cups from anywhere and a lot from my local gas station. Sometimes the plastic red cups too.

I use large 500ml styrofoam cups for winter sowing. Actually they are my favourite type of containers. They are very convenient for transplanting - seedlings just slide out with no effort at all and you don´t have to divide the clumps.

I haven't tried styrofoam yet. What kind of drainage holes do you punch in the bottom of those? That's interesting about separating the seedlings as that is sometimes an issue for me. I think you can buy clear lids for those, too.

No more cups for this year though :-). Will make do with the assortment I have and other odd containers with lids. Have run through all my gal jugs, 1/2 gal jugs and most of my pepsi bottles and planted lots of cups already.

Aliska, I poke 5-7 holes with a pen in a bottom of a cup, sometimes a few to the lower sides as well.

What I meant was that the whole clump of seedlings, potting mix and all, slides out (because of the shape of the cup) and it is usually the right size for me to transplant as a whole. Especially this year, since I have tried to sow very lightly... :)

With larger containers it was difficult for me to get the seedlings out without damaging them. For my small garden the cups seem to be the perfect size.

I just take a letter opener, stack the styro cups 4 high and stab slits in the bottoms.
I use the smaller bathroom cups for the plants I want to make plugs out of, such as grasses

kiskin and busylizzy, thank you. So you do sow HOS but sparingly. That would be ok, and they may slide out more easily than the plastic cups and a little smaller but not too small. Thanks both about the holes, have been burning mine but may not be good for styrofoam.

Some I may not get to until late spring, I could use them uncovered and keep them moist and in the shade until they germinate. Then it sounds like they don't have to grow too much B4 I could slide them out and plant.

Sounds easier on the soil too as to amount needed.

A soidering tool/iron makes it go so much faster, even for the plastic liter bottles and milk jugs. I also used it to put drainage/air holes in top and bottom of Sterlite

pippi, thank you about the burning. I burn holes in almost everything, too, not just the containers I plant in but sometimes what I'm toting or holding them with.

I just got two brand new large pots from Walmart, made of that cheap stuff but durable, would rather have had something else natural but these are light which is a plus. They don't have any drainage holes, and I'm a little afraid to try burning holes in those, not sure if I have a wide enough drill bit. I looked to see if it said anything about holes but couldn't find anything, had to order online as local Walmart doesn't stock them, yet anyway. HD had some of the same brand but not any like mine.
