I bought the same system..I tend to be a brand name person...but after doing the math on my start-up with top of the line(or what people call top of the line) stuff...I realized I could not afford the hydro store or top of the line. I settled on top of the line nutrients(Hesi) starter kit $100, Pro-Mix HP soilless with some perlite thrown in, my trusty ppm and ph pen( i heard about measuring run off and all that..I just test what i put in every time ppm varies as they age...ph 6.2-6.5 never even needed the ph up and down i bought...the HESI nutrients hit it to a perfect 6.2-6.5 every time. Well worth the dough.
NOW..back to the system..I bought the same one with a 6 inch panel-cool tube thingee and hooked it up to a 6 inch exhaust vent running into my attic with an I power filter(just installed in Bloom) 70 bucks.
My plants are beautiful! 2 weeks into bloom, buds EVERYWHERE. ^ plants under 600 watts in a 3.5 x 4 ft space 8 ft high. The lights have never once shut off, or had a problem....I got the whole kit with the hps AND mh bulb, ratchet hangers, etc.. IT IS AWESOME! I think I paid 219 with free shipping! Price the stuff separately or through a hydro store..fuckin joke. 100 bulbs in the hydro store huh...My I power bulb for about 15 in the kit is producing buds in 2 week bloom that rival many of these so called pot gurus on here.
Start with the right stuff, and upgrade as you go. Every week or month I get paid I get something new for the next round.
SO, with that said...order the I power stuff, even if your ballast or light only lasts 2 harvests, replacing a 600 I power ballast is like a !00 bucks! Ill order a new one every year.
