mr123slash123 The bigger one is Titan F1 as well. I've germinated the ones for this diary in 12/05. They are allready getting some nutrients. I give it the Bio grow only. The mixture of soil is very good in my opinion so I don't think they need anything else. I'm thinking of topping one of these 2 to try for the first time. Never topped before so let's see. The bigger titan will be harvested around 10 of june
