you do have a point about some people wanting to see the roots.... but when i grow in cups i know i'll let the plant grow from 5 days to 2 weeks before transplanting depending on the cup size and also plant size.... if its growing rapid, you have a good idea the roots are also growing kinda fast.... but i rather have clear bottoms for when they are in their larger containers... like 3 liter soda bottles.... i watch the bottom to give me a good indication if i should water more and stop spraying the soil... like if the roots are touching the bottom you know you can water and spray... if the roots aren't touching the bottom yet, i'll just keep spraying until the soil is nice and moist, it prevents overwatering for me...
cool tip...
