Thanks, I am forced to grow inside as I live in a valley that seems to be constantly cold and wet and theres a giant sycamore tree at the end of the garden that is home to billions of greenflies every summer. Every time I try to grow outside I find i'm just constantly removing greenflies and due to the crap weather the growth is significantly worse than the indoor plants.
At the moment I am watering very little, around once a week or so and not totally soaking them when I do water them. The plants seem to be happy and the roots are now poking out of the 3l pots, so i think watering less has encouraged root growth. Not sure whether to pot up to 5l pots this early..
I blow hot and cold on this.
Roots will always seek a source of water. So if you always water from the bottom of a deep pot the roots will migrate downwards. If you water from the top of a deep pot and give them enough water that the whole pot is wet then you should get rots at all levels. For sure the bottom up gives less chance of infestation, but personally I see better results I think with top down watering.
