New clones, how long to wait till 1000w?

If I put new cuttings of clones into my aeroponic cloner, I know I should put them under my fluros first to get a root system. But how long should I wait to switch from my fluros to my 1000w MH? This is all under 18/6 veg.

Will one week under fluros give a good enough root system to put them under my 1000w MH? Thanks all

I would give them at least a couple of weeks to develope3 a good root base, but every strain is different. I wouldn't rush it though. You switch over too soon and your plants could suffer from an underdeveloped root base which wouldn't deliver the nutrients your plant requires under the increased light, possibly stunting their growth or even killing th ebuggers in a worse case scenario
