Plants!

6 Tubes of chalking fixed the leak but good, now we plant.  Got about 1/3 of them in.

 This is looking good

Science Centre

 The interactive booth at the Science Centre.  Little kids won the tomato plants if the answered they questions correctly.

 Group shot on the way out.

New pumps installed

Below filling the water tank

 New pump is installed and the water is running.  However there is a leak onto the floor.

Disaster Averted

Turns out a 950 gal. per hour pump will lift water the required 14 feet but will have no push left to travel the 21 feet required.

We scrambled to find a 2600 GPH pump and a new 1 inch diameter feed line that will (I'm told) solve the problem. 

Two steps forward and one back.

175 plants arrive on Friday at 9:30 am.

Air exchange system complete

 fans before and after installation, they are a little noisy. but 550 X 2 cfm's will be.

Grow medium

 The huge roll of grow medium was cut to 21 feet.

 Finalizing the water tank installation

 Installing the grow medium

Relocating the water tank

 We moved the water tank from the wood shop to the classroom.  Not an easy task.  21 foot objects do not bend around doors.  We took it out the back door into the parking lot then in the back of the classroom

 Installing the pond liner.

 then slide it under the wall

 My trip to Nedlaw was great I got a chance to see this 4 year old wall with a flat screen TV in it.  They are growing herbs in this wall as well as tropical plants.
