So here's my setup... Lights: 4 - 100watt spiral cfl's(3-6500k & 1-2700k) Home made hood(DIY's on YouTube) schedule = 18/6 Grown From: Seed Growth Stage: Pre-veg(sprouts) Grow Medium: Rockwool Cubes River Rock(from a local garden store) Strains: Mango KC Brains Mind Bender Green Goo Grand Daddy Purple Grow Setup: 28L clear shallow storage tote(outside spray painted black) White lid that came with the tote 12 - 3" netted pots Aquarium Air Pump(1 out port) Check valve & Air Tubing(Standard diameter/size) 24" hydroponics flexible bubble stone Nutrients(per growth stage): Pre-Veg/Rooting: General Organics Bio Root Vegetive: Canna Aqua Vega A+B Flowering: Canna Aqua Flores A+B Harvest/Flush: pH balanced water & molasses Now that you have a general overview of my setup, let me tell you about my growth. When I began, I started by germinating each strain listed above via moist paper towel & plastic ziplock in a dark semi-cool place. After 2-3 days each strain cracked and was ready for the rockwool. After being inside my propagation room for 3 days under 18/6 light schedule and temps of 68F - 78F, the seeds have broke the surface. I've had absolutely no issues at this point. I clean my grow space once a week with a mixture of organic home insect killer, organic insecticidal soap, bleach & liquid laundry detergent. So my grow space is kept well. Prevention is always better than cure! My question: So all of my sprouts have roots obviously but they have great roots. I recently purchase a 32 oz bottle of General Organics Bio Roots. Its my understanding that with clones, a root stimulant would not produce much result since a plant needs roots in order to take up nutrients. Is this true? And my other question is this... has anyone ever used this Bio-Root? If so what were your results?
