I'm using biobizz Rootjuice at the moment it's my first time with it so hopefully it's a goodinI use rhizotonic by canna for the first 4 or 5 weeks after the second watering I use at full strength (4 ml per ltr of water)for 3 weeks then back down to half strength but watch your ph when using it as it takes my ph 7.2 to 9.8 then after about 5 weeks no root boosters at all :smoking:
