I totally agree with knowm. I was a lazy fucker with my first grow. Alot of new growers don't take into account pH or it's impact on plant growth. Take the time to understand every little thing fully. I read like hell through all the FAQ's on overgrow and now I'm pretty confident and happy with how things are growing now... sure, you have the lights.. The fans, the soil. But when it comes down to it all, equiptment isn't the half of growing... Would you buy a car not knowing how to drive?
