Its pointless using nutes when their isnt a root system to absorb them, I would personnally use the box with the light as I think letting it do it naturally in daylight would take longer.yeh yorkie told me that too and only about 8 qwid on ebay or less
il do it tomorrow dunno wich to try as ive got the box lined with thick mylar(grow tent panels) and a 6400k to clip to the lid that wil be fine u reckon? take the cut rough the edges and put into coco and a inch? NO nutes
yeah bury the bottom in your medium about an inch or so and you will be spot on.
I think the powder works better because when it gets moist it turns it into a paste type of thing where as gels could wash away easier (possible but thats just my logic)
