Well there seems to be alot of confusion about Neem oil. The Azadirachta indica is what is refered to as the "Neem Plant". Products bearing the Aza prefix of the name is NEEM oil. Azatrol, Gnatrol, its all mostly neem oil. As you can tell by the name it has alot in common with the cannabis plant. It grows in the same region where many of worlds stongest indicas are from. Interesting enough, the active ingredent in Neem, the Azadirachtin, is produced in the same way as THC is produced in cannabis. Its a product of the a secondary metabolit ( when the plant breaths, the waste product oxeygen is used to make Azadirachtin). Same thing in the pot plant with THC. Funny enough, the active ingredent works on bugs much like the way THC works on humans. It's molecular structure is very similar to a hormone in the bugs and it covers receptors in their brains. It fools the bugs into thinking its time to mate when they are not ready. This prevents them from doing many things: eating (they dont suck the sap out of your leaves), laying eggs (stops the life cycle), prevents the the exoskelotons for thickening and hardening (they puncture and die easily). Its organic and very safe on your plants. Also, it wont hurt your lady bug friends. The Neem plant and the Cannabis plant have been used hand in hand for thousands of years and its still one of the best things you use on you plants today. Here's link:

Very nice grow. Good luck and hope you can solve the mite problem.
)added 6 holes so i (me lol) dug out a third of the dirt and amended it and added fresh dirt to fill. still never put the fencing in and have not had a problem. so wish me luck. one of my ladys did pass away at about 6' tall(rip). but i think it was because the stem split and i taped it up. it healed well but i forgot to loosen the tape. so i think i killed it
