ok, ive soaked the rockwool in water, i added ph down and it turnt nearly the same yellow as 6.0 on the chart so im just using that. in all the tutorials ive read they dont tell you what to do once the seed has been put in the rockwool. my light isnt set up till tomoro so wud it be better to put the blocks in my airing cupboard or on a window sill somewhere? thanking in advance.
