Absolutly, I would watch jumping to such a big pot so fast.
What regin are the plants grown in?
How big are the plants as of now?
I dont know what your season is like, But, if I use Ocean Forest outside where I live I will have to water at least twice a day.
Only reason I say this is cause I know. Check out my thread "In the mountains.2009" All of that was grown with Sunshine#4 and FoxFarm Ocean Forest.
I HAD TO WATER 3 TIMES A DAY IN THE HEAT OF THE SUMMER!!!!!!!!
I have since moved on to a Organic mulch/compost/manure mix with nice results. So far.
Reason is. Indoor mix's dont do so well outdoors and that mix is for maximum aireation and will dry out very fast on you so be careful.
I would ask what your intendid harvest size was?
