Tomatoes splitting

My first truss to ripen this week had 3 fruits (Shirley) that split their skins.
I hear this is maybe because of inconsistent watering, is that right? I water when I remember, generally every 2 to 3 days, and I feed once a week. My plants are in a growbag in a poly grow house, so with the high humidity I've generally not worried about watering too often.
The flesh was fine by the way, I skinned the fruits and ate the flesh raw, it was delicious, full flavoured and moist. I think by the looks of it they'd cook well too. Is it a major problem if they split by the way? Or just a presentation thing?

 

i am no expert and others who know more will reply but grow bags need lots of water. I have mine in pots outside and water every day unless there has been heavy rain. In a greenhouse I would have thought daily watering was essential. Everything dries out so much at this time of the year especially under glass

 

Mine are in tubs in the greenhouse and i make sure they are kept wet by watering at least once a sday if not twice, every other day gets a feed too. They just use so much water each day its hard to keep the compost moist. I had some spuds outside in the same size tubs as my toms and when i emptied them the other day the compost below 4" deep was dry as a bone, even with all this rain we have been getting and i water them each day too when it hasnt rained. I think its best not to put drainage holes in a grow bag or smaller pots when growing toms or spuds, the plant will use all the water anyway, no point in drying the compost out more than it will do on its own.

 

I've found that Pots and Growbags are too much work, so I've planted mine in the greenhouse border this year. Its a world of difference, I water every other day, and have a fantastic amount of growth on everything in there - way more than I got with pots previously.

 

Interesting John, do you reckon Outdoor Toms taste better than the (forced) indoor ones?

 

Thanks everyone, seems I need to water a bit more consistently by the sounds of it.
I'll continue to use the flesh, sounds like the poor watering isn't doing the tomatoes any harm apart from cosmetic. I'm using them right off the vine anyway, so no storage issues.
Cheers! :gnthb:
