Hi, its my first jump into growing auto fems. I am a bit unsure of what size pot to use (soil) as they are not very high growing so does this mean can use a smaller pot. I have some 3.8lt rhizo pots. The soil I use for other stains ie: higher growing is the Bio biz all-mix, now would it be OK use same or any advice on what I can use from pot to feed etc would be very helpful. Thanks boldy.
