Thanks for the suggestion GPS, but thats not rockwool... the ones I started on rockwool.. were the ones that died
this is like a foam... its called hydroculture oasis ore something like that... its what commercial growers use here in Puerto Rico, directly on the tube... it hold swater but not that much as rockwool....
All the
seeds were planted at the same time... but there are different kinds of lettuces, that's why they grow at different speed
We planted for us and our family and close friends... to share
