I read this forum almost every day and am continually amazed at what people do to try to get killer bud. Talk about taking something fairly simple making it rocket science! The system I've been using for some time now is the commonly known as the "Lucas" method. By using this method I have eliminated nutrient lock-out, over feeding (burning), overpriced nutrients, weekly water changes and many other headaches that come along with all those pretty bottles the hydro store loves to sell you. I flower in a AeroFlo 36 system with a 1000w HPS, but I only flower 8 -12 plants at a time to make a 4' x 4' canopy. I clone in a EZ cloner under T-5 for about 14 days. I start about twice the amount of clones that I need so I end up flowering only the "all-stars" of the bunch. I veg in a modified EZ cloner under T-5 also and they usually go for about 7 to 14 days. My clone and veg times are dependent on root mass, so a plant never goes to the next level until they are ready.
Keep it simple people!
