i was wondering about this to, due to the fact i water three times a day....(small amounts less then 2 oounces of water per plant). this is becuase there in a 3 foot tall by 3 foot wide planter with a huge tree in the middle. the plants are on the outsides of the pot so they get some shade from the HOT ASS TEXAS SUN..
Its a 100 degrees everyday with direct sunlight from about 8am till 9pm

my question really is how much water should a 6inch sproutling get? on a daily basis?
