@Dirtydraggel, Hey man not sure where you're from but I've just ordered a 5pk. Don't know if I'm allowed to advertise here neither as I've only been here a few days. I'm UK.
@stone, hey, nothing professional, I have several setups going with a mix of full spectrum cheap 300w panels from Amazon and simple E27 high output LED bulbs from a regular DIY store. Cool white for veg, warm white for you know. My “most expensive” aparatus is my “PAR” meter, if a 10$bulb gives me 2000-5000nm at 15cm distance, I can grow a decent 40g/plant with it.
(Simple cfl for early veg)
