Ok gang, a quick follow up question:

I emptied and filled with pH correct water last night. I also have a couple of submersible pumps from a prior drip system that I can use to run at intervals to leach the medium (hydroton) and roots.

So the question is: How long should I let the bubbler do its thing before harvesting?

Or: If I add a large volume of water on an aggressive schedule by pumping over onto the medium (I'm talking 5 minute intervals using a 150 gph pump, straight fed thru a 1/2" hose - a massive 'drip' effect), will this help speed it up?

Also, how long will I need to wait til I can harvest without compromising the taste and smell of the herb?

I'm using Botanicare Pure Blend Pro's Bloom / Sweet / Karma and the Botanicare 'schedule' says 2-3 days at end of flower...

Thanks for your help
