For the cheapskate grower , its simple head to home depot .. Purchase your t-5 units , they are a little cheaper but you ll most likely have to wire it as well .. You could use T-8 shoplights , they are always priced under $20.oo with bulbs .. Good luck finding a decent HID lamp while there though , they only sell wall mounted security lights and they are low wattage and a waste of time ..
You might as well head to the opposite end of the shopping center and hit Walmart next , you ll be able to purchase Miracle Grow at its lowest price including soil .. Maybe you ll be lucky and they will have some Miracle grow perlite as well .. Next up hit the camping section and grab some emergency space blankets .. Spin on over to the paint area for buckets if needed or grab 20 gallon laundry totes .. Solo cups for the HazeyGrape type growers lol
Last but not least , munchies .. Might as well buy some shitty food with no value as well since this is what you ll be growing with .. Enjoy the cheapskate grow for all its worth and thank Big Box companies for there existence ......Peace
