The MAIN difference is the T8 is bigger than the T5. The "T" stands for the shape of the fluorescent. Which in this case would be tubular. And the number stands for the diameter of the bulb in eighths of an inch.
Good Questionwhere can i find 500+ watt cfl in 2700k?
18 40w CFLs will do that.. I suggest dual exhaust and possibly some frozen water bottles in the box.Any and ALL ideas are welcome. I'm currently constructing a 2'x2'x4' closet grow. I'm using a 4" duct fan (80 cfm) for my air exhaust, and a 14" tower fan to circulate air within the closet. I have all 4 walls completely covered in black/white poly paper (85% reflective). My lighting is 18-40W CFL (6000K) totaling 47,700 Lumen.
Before I started my grow I wanted to test the room fully equipped with my hygrometer. The results: 102 F and 18% humidity!!!
Please if you have any SERIOUS suggestions feel free to give them.
Impatiently being patient...
Thanks for the suggestion. I'm going to reduce it to 6 CFLs and test the temps again. +rep18 40w CFLs will do that.. I suggest dual exhaust and possibly some frozen water bottles in the box.
Honestly, if my plants are totally dry of water my temps can reach 91 and once I water my plants it can drop to 75...
Oh yes, this is done all the time! It's called the "Screen of Green" method. Check out the following linkif heard of people training their plants to grow within a foot of space under like chicken wire, isn't that possible?
Yeah dude you've got the spectrum spot on but I suggest using more lights/watts for flowering than you do for vegging, it'll work either way though.So could I use 2 65 Watt (6500K) for veg and 2 45 Watt (2700K) for flowering?
