ive always used 1000 and 430 hps.. but i recently got a t5 4 foot 8 bulb and pulled 4.5 oz dried and cured.. a skunk variety but not elite or heavy yeilding pheno.. just a nirvana single femed seed off the web buds were beautiful and good buzz

well on a 4foot 8 bulp expensive setup i could see it

www.TekSupply.com 130.00 for a t-5 4 foot 6 bulb.. you could get the same result i got with this and a good strain and proper care .. maybe more..

and u would get twice as better with a HPS i don't get the point and it has 2 FOUR FOOT bulbs less then urs that's a significant less

i mean there great for vegging dont get me wrong but grow buds all the way threw with that would not be ideal

the point.. more than one point .. t5's are better than hps in tight areas.. little closets grow box's small tents.. when you cant use hps because of heat t5's are GREAT.. thats the only argument here.. its obvious you get higher yeilds with hps but they put off heat and too much heat stops growth and creates a shit load of problems.. and yes they are great for vegging.. and they are great for flowering.. unlike leds.. its a power consumption, heat issue .. t5's are superior. in both catagories..but if you have the space and fans ac dehumidifer etc.. go with the hps

how would u fit 6 4foot lights in a little closet? u sure could fit a 150 HPS or even a 400 with circualtion like there should be in a any grow room anyways. and it would cost the same. t5s arent as a cheap like t8s and t12s
i suggest the TSer download a movie on torent called jorge cervantes ultimate grow 1

exactly with circulation...t5 are better than t8 etc .. so why not go with the t8's or t 12's.. jorge cervantes is a growing genius i refer to his cannabis bible all the time.. fav book of mine.. if your closet is 4 foot by 4 or larger with no vents or circulation i thnk they are ideal.. especially with a sog

dood if u read jorge u know even a tiny closet must have circulation for proper yields....theres alot of reasons u see shitty grows on RIU....and Jorge would never flower with fluros as i wouldnt eether now that ive had HPS and one of my grows was in a closet and i ran 4ft T8s with HPS way more of yield then with just the I think 8 4fters of them i ran with suplement CFLs on the side in the beginng

all im sayin.. i grew in a 8x5 closet with no vents 8 ft ceiling used a t5 8 buld and got 5 oz's.. and the 400 was too hot.. i got more from a t5 and one big plant than a 400 hps with 5 plants
