what needs to happen. is u water the plant.. let it grow.. watch the cube.. feel the cube.. if its kinda crispy on edges but still moist on the inside, then wait another 8 hours to water it. You know as a grower you got to kinda eye ball things sometimes.. so use your best judgement.as big as they are right now, i'd go ahead and take the cube and all and put it in dirt so you can tell easier.
