one, you're going to have a smelly mess in a couple weeks. raw meat in an indoor grow is not advisable, especially fish, . two, seeds do not need added ferts to start and if you can't afford the 6 bucks for a decent bag of potting soil now how will you be able to afford the cost of electricity and other supplies you will be needing?

3, just stick with what has worked for millions of us over the years and follow the basic guidelines. the 1st grow is the hardest and the only way you're going to get any kind of harvest at all worthy of the time and effort is to leave the experiments to the experienced and those who have extra plants to play with and are better able to handle the loss when the experiment fails.

4, common sense and patience are must-have's in this biz and putting fish into an indoor grow is not using common sense.
