Nutrient film technique

Started these off in rookwool instead of the usual jiffy pellets I use as I found 👀some sort bug trying to burrow in the pellets of another strain that sneaked in my veg room. (See pic I stuck the cunt to the fly trapIf anything has more than 2 legs in my grow rooms it DIES 😂😂 So that's put pay to using them anymore. I used them for ease as you just soak the pellets and off you go. With rockwool you have to pre soak them in ph'd 5.5 water because of the lime content that cant be processed out when being made blah blah blah. With the above blocks I've soaked them in Ph'd 5.5 water for an hour with a splash of formulex too just for good measure 😉 Ps, Thanks 🏆Mark🏆for these unexpected beans...that was a nice gesture ✌️
