Mini Aquaponics 1 Day 2

Wanted to build the floating raft today, so went to buy some polystyrene and cups for the construction material.

Floating Raft Holes for cups

 Decided to cutout a few different layouts to see if there are any differences in growth. The four layouts are listed below:

1. Two small holes at the bottom and big holes on side
2. Single large hole at the bottom and big holes on side
3. Two small holes at the bottom and slit holes on side
4. Single large hole at the bottom and slit holes on side

Cut out some holes in the cups, 4 different cutouts

 Put some stones in the cups, placed it into the the polystyrene. Lets hope the polystyrene holds the weight.. Plopped it into the aquarium and the polystrene sinks half way. *phew* it works haha..

Floating Raft with stones in it

 Since the roots absorb oxygen, I placed the air stone directly under two of the cups to see if that makes any difference. But I wonder if the air bubbles are too big to be absorbed by the roots?

Under the raft, lots of air bubbles
