I realized I don't have enough hydroton to just use the rockwool cubes alone, so I transplanted the 6 to slabs..

They have all started poking out

I am planning on leaving them in the slabs without hydroton until i start flowering them, That way Ill at the most have four females...
I only have enough hydroton to plant four plants...

Hopefully they will not become rootbound in the rockwool in the next 4 to 5 weeks..


Should I just continue to water the rockwool by hand when it appears dry?
No nutrients yet, right?

Should I just put four of the slabs into hydroton in a couple of weeks, and leave two out and hopefully the two that aren't in the hydroton are male and not female?

OR... should I just order more hydroton so that all six can be moved into buckets in a couple of weeks, even if the roots aren't poking out of the slabs?
