3W Grow Light Planter

thingiverse

Small compact LED grow light, built in watering port (front), excess water collection and evaporation vent (back). BOM: - Grow Light 3W 400-840nm (https://www.aliexpress.com/item/32814205527.html) - Resistor (For my particular build I used a 1 Ohm 1 Watt but you may require a different setup based on your power supply) (https://www.aliexpress.com/item/32803425964.html) - M3 X 3 X 5.3 Embedded Nuts: (old link no longer works - possible substitution M3 X D5 X L3) https://www.aliexpress.com/item/4000232858343.html - M3 X 6 Machine Screws: (https://www.aliexpress.com/item/32798146322.html) - An Appropriately Sized Self Adhesive Heat Sink (No part specified as sizing will depend on heat dissipation requirements and your specific operating environment - do not operate without a heat sink - for my build a 14 mm X 14 mm heat sink fit well) - DC Power Supply 1A 3V (no part specified as you will need to use one appropriate for your region / local requirements). See notes below re: alternative methods to drive LED. - Suggested alternate driving method vs resistor shown in post 1.2 V - 3.6 V input 3W LED driver - I think this has current limiting to 700 mA but as I've not used one myself yet you will have to do your own research on whether this is suitable https://www.aliexpress.com/item/33009837807.html Update 3/15/2020 "Iz kinda smol" - Added a tall version
