G,

To come up with plant money, sell some plants on line to pay for it via a paypal account. That is a very easy way that incurs little real $(some make a fair amount doing this every 2 weeks) and you should be able to sell plants on line there easily for a good $.

I suggest this as it takes no new $ and many toss out extra cuttings anyway.
You should be able to pay for Ferts and little items this way.
Some pay for their electric as well doing this.

So after the initial cost of set up, the rest is a self sustaining hobby $ wise.

Regards,
Tom Barr
