New to hydro here it is

[Easy Roller]

Any input

What wattage light ...is it a 1 planter....

Looks like a home made job..nice idea ..two buckets [res' and tray]......you could fill the top tray bucket with medium [gravel or clay balls]...

I see you've used a smaller removable pot to house the plant...nice idea..coz you can remove the plant but maybe the plant would benefit more from the maximum space the bucket itself has to offer.
