Yeah!
Wipe the leaves down with Neem oil and get hold of some predatory mites.
I have had plants ravaged by Spider Mite and managed to take good weed from them.
I think it depends.
I had a 250w red with a reflector and a 150w blue just hanging over four Blue Cheese and they did as good as my 400w hid.
I was shocked but delighted.
After growing outside for a few years i moved my grow indoors...now a couple of years on im thinking about moving out of soil and using Coca.
I am looking for people who have experienced the benefits/pitfalls of growing with this medium?
Thanks Guys.
Its usually 25 hours in one of my days but i can get up to 30 depending on how much i smoke.
There is definately not a dry summer in store for the UK but good luck with that dream mate.
