Tomatoes (what size container?)

Meomye

I have recently purchased two tomato varieties, Red Robin and Tumbler, both in approx 10cm pots. The RR says it can be grown on a kitchen windowsill and the Tumbler says a hanging basket or container. My question is, what size containers do I need for them? and in what potting compost? I do not literally need to put RR on the windowsill as I have a small conservatory that gets very sunny and warm. Tia

As long as you can give them lots of water and feed its not critical. That said a bigger container is much easier to manage ( from the food and water point of view). Both these varieties are compact ones but my advice is go as big as you can, then if you are away for a weekend say then they will cope better. For the hanging basket go for 12 inch (30 cms) at least. For the pot  I would go for 3 litres minimum.  Remember all compost growing mediums only have enough feed for about 6 weeks.

Although AB is right about it being easier to keep the watering steady in a bigger pot, you'll get more fruit if you grow them in a smaller container (or more than one in a larger one). It depends how diligent you can be with the food and watering

I've grown cherry toms successfully in clematis pots, which would be 3 litre probably, although I usually use something a good bit bigger -about 10 -12 inches diameter.
They're also better not overwatered or over fed. They get too comfy if that happens. A bit of stress pushed them into flowering, and therefore fruiting, which is the point of the exercise. Watering should be consistent though to prevent problems.

Thank you everyone for your replies. @Fairygirl, how often should I feed and water 'in order that they do not get too comfy'?  and also, am I correct in saying there is no pinching out required with these varieties? t i a

I haven't grown either of those, but the Tumbler shouldn't need pinched out as it's designed for a container. Most of those are bush varieties.
Watering should just be consistent - and that's best done from the start. I let my plants get slightly on the dry side before watering. Mine are always grown undercover though, which generally makes it easier. Not suitable to grow them outside here.
As for feeding - you shouldn't feed until the first truss of fruit is set. Each time you pot on into fresh compost, there's enough nutrition for them. Feed will also depend on the variety and the growing conditions. 
I rarely feed more than twice after that first one. It just isn't necessary, and by then it's getting to the end of their lifespan [around late September early October] so it's a total waste of money. Some people will use a more diluted feed each time they water.  I tried that in the past and there was no difference in the crop, so I've never done it since

If you google your varieties, you should be able to get info as to whether they're cordon  types or bush - indeterminate or determinate.

Yes, what Fairy says, are you intending to keep them in your conservatory. I only pot on twice, once to 3 inch pots, then their final position, some in pots about the size Fairy suggests, some in open ground, so I do feed weekly. Have grown Tumbling tom in 12 inch basket.
