I have a 600w hps & 400w MH. I was thinking of starting my clones on the MH 24/0 but thought the hps might be better for growth. Any thoughts?
How many of them are you starting? If you covering a huge area doing sog I would consider the 600. Otherwise the 400 is more than enough.
Acid, what do you mean "clean soil"? I re-use my organic soil for years and years and years (I will never get rid of it) and don't do anything to "clean" it. If you are talking about soil that has been treated with chemicals, I don't know the you should be re-using it. If you're talking about organic soil, check out the thread in my signature, post #3. Welcome to GC and happy gardening!
I use Voodoo Juice as a part of my growing regimen...works well to support root health, which leads to growth. Voodoo Juice, Root Booster, Roots Organic Nutrients, root lifter and volume booster
A mycorrhizal product. VAM endomycorrhizae from BioAg. $18 shipped for 100g. Best mycorrhizal fungi product you will find. bioag dot com BioAg's humic acid (Ful-Humix) and fulvic acid (Ful-power) products are also excellent- some of the best humic/fulvic products available, and worlds better than what's available at the average grow shop . Don't mess with superthrive. Spend your money on real-deal products with documented science to back them up. Typically, products that claim to be these "miracle products" that promise amazing results don't live up to the hype.
