Thanks for the info online the koolbloom I've always used it with great results but that was with photos so I'll discontinue it from my feeding program. Yeah the 150 hps is rated at 16,000 lumens the t5 is also rated 16,000 lumens I just figured he extra lumens couldn't hurt. I've also read about people having better success flowering with the 6500k than the 2700k is this true to your knowledge? The 150 hps seems to be doing just fine by itself although I must say the t5 vegges beautifully. 16,000 lumens should be fine for 2 autos anyway I believe, do you think 150 hps is sufficient for 2 autos? I appreciate all your info bro, I'd rather ask 1 person who knows what it is than get 10 different suggestions from 10 different people
