Tomato issues

I grew 8 tomato plants this year, and as usual in Quadgrows.
Therefore water level & nutrition kept constant,

I had a significant quantity of fruit, but other than the mini tomatoes .. all standard o large tomatoes split .... almost 100% of them

Normally expect a few splits, but never had this much problem.

Suggestions ?

 

Some varieties are prone to splitting no matter how well you look after them. What tomatoes were you growing that split?

 

All of them, Shirley, Tigerella, Supersteak
Only the mini toms didn't split

 

Greenhouse or outdoors? I personally haven't grown the ones you've mentioned so I can't say much about them. However, I grew around 10 varieties outside and only one variety continuously split (a large yellow cherry).

Were they ripe when they split or before? Because if they were ripe, the weather being cold and warm has sped up ripening somewhat so splitting is expected.

 

Greenhouse

 

I suspect the rainy weather increased the humidity in the greenhouse so watering is your issue. I find growing indoors do be difficult because you have to be on top of it everyday!

 

Weather....

 

I'm not sure what quadgrows are but I always put splitting down to too much water after perhaps the fruit has actually stopped growing.
The skin can't expand when it gets extra water so it splits.

So maybe a combination of watering and fluctuating temperature perhaps.

If you have removed a fair amount of leaves it might be best to hardly water at all.
