A question about weight

Greetings.... Here's something I am hoping an experienced indoor grower will answer. What is the most cost effective, simplest way to add weight during flowering? I'm growing for myself, in limited space, and on a low budget. I'm not fond of the idea of using lots of chemicals anyway. Help would be greatly appreciated.

If you are growing for yourself, considering how fast it grows and the surplus you will surely generate, what does 'weight' have to do with anything? Seems abstract.

When you grow for yourself, think 'quality' vs 'quantity'..

I mean you asked.. my point is 'weight' and 'bulk; mean little compared to just being grown in as stress free of environment as possible, and producing the maximum potential that strain has to offer.. which has NOTHING to do with weight..,

If that makes any sense.. just trying to help someone who is 'growing for himself' out.

What I mean is, I have grown some bud that defies gravity (seemingly weightless) that will rock as much as shit that weighs a metric fuckload (for example).. smoked and tasted better too..

What I meant by growing for myself was that I am not a caregiver. Anyway, my concern was having enough to do through until the next harvest...90 days. Totally agree about quality vs. quantity. Obtaining quality plants here is difficult, as I just moved to the area, so don't know anything or anyone....lol
