Is there anything (inexpensive that I don't have to order) I can add to soil to keep ph at a good level.Just wondering because I use bottled distilled water, so I never bother with Phing the water.

Do you know if a 6500k bulb benefits a flowering plant. The reason i ask is one of my 2700k bulbs went out and i replaced it with a 6500k bulb. Do you think that will be okay or should I buy another 2700k bulb?

buy another. flowering plants do not benefit from blue spectrum bulbs. in a pinch you can use a duel spectrum, but best to use MH for veg only and HPS for flower only when generally growing.

Umm, not true...I use a mixed spectrum...I use a ratio of 3 to 1 in all my rooms...I have 6-2,000w dual spectrum Raptors (1 side is a MH and the other is an HPS) and it works fine and I think my plants like it better than just "one" spectrum...they grow at an alarming rate, I can go from bean sprout to 3ft plant in 10 weeks (I do use a supersoil) and get 6oz+ off of each plant at harvest...peace and good luck...

I never grew autos,but a mixed spectrum is desired.I used regular shop lights starting out long ago & used that 3 - 1 ratio,it was hard at flower time. You'll be fine with a 400.

edit:I just reread what riknstein wrote,that sounds perfect,I did not realize that both side could run @ the same time.
Must be a lot of heat to get rid of.

Yep, that's why I have all my intake filters hooked up to there own A/C window units...and all exhaust filters goes through my roof 40 feet in the air :clap:...........EDIT: Your ballast has to be able to handle it, I have a digital ballast so I can switch from single 400w, 600w, 1,000w or I can double them for my 2 bulbs (MH & HPS)

stop hijacking someone elses thread. make your own.

RIK, i said blue spectrum bulbs, not dual spectrum bulbs, should not be used for flowering. please re-read what i posted. and if dual spectrums were just as good, we would all use them rather than buying double the amount of bulbs. i have used them both, and HPS easily out performed dual spectrum. but it is personal preference, i guess. but i never stated that they don't work. so please check before arguing. also please feel free to check the spectrum ranges on MH bulbs and countless scientific reports on the importance of the red spectrum in flowering cannabis which MH seriously lacks.
