there is simply no substitute for light, invest in a lighting system if you must, ther5e expensive, but worth it. and i've heard of the rusy nail being put in the bottom of the stalk before harvesting it, but never have i seen it done. i think the rusty nail thing is something mainly done in mexico and south america, i thi9nk this because i've only heard mexicans and south americans talk about it. they swear by it, and it could very well work, but their mainly growing sativa, and if your growing indica it may not like it.
