^^ What SCIENTIXT said.

Only thing I would add is:
1- you need to do lots of research. That's why his answers on the light were 'vague'.
You should find that information within the first 10 minutes of your studies.
2- ScientiXt, just wondering... but what do you think about the soil mothers?
I would think that mothers in soil would be a good idea, then your clones and grows go hydro.
I believe that hydro mothers are too much of a hassle, although there's no reason why not.

Just wanted to hear your thoughts on the matter.

Best to all,

turtle420 Reviewed by turtle420 on . Whole Bunch of Questions DWC So I do not have any clones at my disposal but I plan on ordering white widow seeds. I'm looking at building a DWC system. Should I grow my seeds in soil for a potential mother? How much space should be left between plants? Should the air stone be on constantly? Should I use distilled water? Rating: 5
