Hi,
I have just bashed a growdrobe together (6' high, 6' wide, 2.6' deep), 424 tank, 200w enviro (for my 2-3 weeks veg), and an old skool 400w sodium growlight (the kind that has the ballast and shade all in one unit and heavy as hell!!).
Anyway, being a bit of a newbie, and friends all having conflicting views (tut and sigh), i'd appreciate a bit of help.
1. I understand the ph needs to be about 1.2, wondering if this includes the ph of the water or not?
2. What is the best temp for the water in the tank?
3. Is it ok to use the 400w sodium bulb for my grow in my growdrobe without buring it down! I have a 12" fan which i intend to put in the room, but as yet only have a simple electric extractor 100mm lodged into the side of the hardboard.
I know a good extractor fan is needed as with a bit of angled ducting, but thats not affordable till the first grow is done.
Will the loss of light through the extractor fan make much difference?
Well, thats about it (for now!), thanks in advance for all your help.
I'm still trying to figure out the science of it all, like whats the diff between ec meter and ph meter, and is it the nutrients that affect the ph or the ec?
I know it's not rocket science, but knowledge is power and i can say, hand on heart, that i'm a bit wet behind the ears with all this hydroponic malarkey.
But... i am keen as mustard to learn and no better place than this forum, rather than the many 'pub' experts who have shared their totally different wisdoms!
many thanks, chris.
