where to begin?
A material list I suppose?
4x 1/2" PVC elbows $3.20
2x 1/2" PVC T fittings $1.60
1 1/2" threaded 1 side T $1.20
10’ 1/2" PVC pipe $4
6x sprinkler heads $1.80
102L tote 27Gal $9-11 price varies
pond pump $29
PVC primer and cement
Start by measuring tote then find center from there
cut 2 small pieces of pipe deducting 1-1 1/2" per fitting in my case this worked out to 2 6" pieces dry fit 3 T’s this will give you main branch from pump. From this main branch you measure and cut 2 more pipes factoring 1" for elbows
this is basic break down of pipes and fittings measure a pipe for each end by measuring across main T branch with outside T’s removed dry fit everything
It should look something like above picture
Prime fittings and pipes
While primer is drying is a good time to paint lid and add a drain fitting to bottom of tote I use a 5/8" threaded elbow and add 2 hose gaskets to it
this elbow drain serves 2 purposes 1 I can see water level 2 I can add pump or simply use gravity to drain I connect a hose to it and loop it above nutrient level
By now primer should be dry enough to glue pieces into final configuration work fast add cement to pipe and fit together 1 piece 1 fitting at a time a properly primed fitting will set fast so direction of each fitting will be a critical factor as you won’t be able to adjust after a few seconds marking during dry fit likely would be wise choice
Give this a few minutes to set fully pain lid hopefully second coat if you did first at same time as drain?
Grey or light brown anything but white or black
Black collects heat white takes way more coats to prevent light leakage so twice the pain though a primer grey undercoat or 2 then white may work
We paint to keep light out so several coats works best
cement now set we mark and drill holes for sprinklers 5/64" or 5/32" lol forgot to write it down I just match bit to bottom of sprinkler head
I used a cheap and simple threading tool to thread holes after drilling smallest thread on it after threading I simply wound sprinklers on end result below
6 sprinklers installed facing up or top of unit
and after attaching pump to manifold
I cut a notch for pumps cord oriented in direction of drain may fill hole with silicone after but my other unit doesn’t leak so will adjust accordingly during dry run.
lid is still drying after 3 coats but dry enough to mark where I will cut out
Net pots also needed a trim
after cutting holes in lid will attach hose to drain and fill unit for a flush cycle and to test action on sprinkler heads.
This unit will house 2 plants and run on 5 Gal fill roughly like the other 1 I already have going pump is on timer for 15 min intervals adjusted based on temps since pump warms nutrient solution net pot could utilize clay pellets or coarse coco
