How to get fastest growth rate in veg

High phosphorus feeds a few days after transplant definitely makea for explosive root development. No doubt. If using a hydroponic 2 part veg and bloom feed....a good idea to use the bloom after every transplant.

Why are soil guys in a coco thread trying to debate weekly potting? Coco your goal is root bound and multi feeds a day. Besides 3 gallons pot size really the most you need unless growing trees. For the soil guys in hydro area it's not soil it's hydro

I've made a decision to veg for 9 weeks now.
I'm feeding recharge every other watering.
Plants are now 5 days from clone and got there first topping today.

Does anyone know of any inline timer valves thats battery operated that does seconds and minute cycles? The ones I have now are only minutes and hours that served me well for longer feeding frequencies
