This guide will be in 2 parts as I am still waiting for some of the stuff to arrive. This part will cover getting the first lot of holes drilled into the buckets and fitting the digital thermometers.
Some of the items on the shopping list are optional and smaller pumps can be used.
shopping list.
3x 20l black buckets with lids (20l buckets are the smallest I'd recommend for this type of system but you can always go bigger.)
1x 2400l/hour water pump (I wouldn't go below a 1500l/hour pump for this size system and it's always better to get bigger when possible.)
1x 80l/m air pump (a 40l/m air pump would be sufficient, as with the water pump, getting a bigger pump will be better where possible.)
7x 1/2inch Uniseal bulkheads (solid plastic bulkheads can also be used if you want.)
19mm pipe.
2x digital thermometers with probes (optional.)
5x19mm 90 degree barbed fittings.
1x19mm T barbed fitting.
32mm and 140mm hole saw bits (32mm is the bit required for the 1/2 inch Uniseals and the 140mm is for drilling a hole in the lid for the net pot.)
Knife (for cutting hole in lid for thermometers).
2x 140mm net pots.
Cost of around £200-£250





1st drill 3 holes with the 32mm hole saw bit in 1 bucket this will be the reservoir.

Then put 3 of the Uniseal bulkheeads into the holes.

Next drill 2 holes in the other 2 buckets then put the Uniseal bulkheads in

I decided I wanted to keep an eye on the temp in each bucket so got 2 little digital thermometers with probes and cut a hole in thee lid for the thermometer to sit

The flexible tubing I chose is quite soft and the Uniseals are quite taut to push the hose through so I cut a small slit in the end of the pipe to make it a lot easier to push through.

This guide will continue as soon as thee rest of my stuff has arrived.
