Grapes (Vitis vinifera) are no harder or easier to grow than any other fruit as long the variety is compatible with the local environment. Be it indoors are outdoors, red, white or black, seed or seedless.
The art to successful grape growing is as again with all other fruit, variety, temperature, nutrients, water, air flow and pruning regime.
You have to be ruthless in thinning out the grape bunches. I know it seems harsh, all of those small bunches of grapes growing well. But in the long term its for the better.
All of our varieties are grown outside, on a cordon system, protection must be given against the birds.
