the grodan website has some very technical information on water management guidelines. one thing im curious about is this: http://www.grodan.com/sw55949.asp "Start and stop time Irrigation start time and stop time, in combination with irrigation volume, can greatly influence the course of the water content in the slab and in turn, plant growth (Table 9.). Early start time = 0-1hrs after sunrise (ie lights on) Standard start time = 1-2hrs after sunrise Late start time = 2-4hrs Early stop time = 3-6 hrs before sunset (ie lights off) Standard = 1-3 hrs before sunset Late = 0-1 hrs before sunset To illustrate these concepts, here are some examples of strategies…

I have 2 definate large AK females and 2 cant tell (most likely male) that have been in veg 7 weeks. I was going to start flowering this week and was wondering about lighting. I have a 400w MH and 1000HPS. If i only have 2 plants is it worth it to put them under the 1000w or should I get a warm spectrum bulb for the 400w and use it to save energy?

Was thinking of using Miracle Grow as it's readilly available at my local garden centre. I live a long way from any Hydro places, so anything I can buy at the local garden centre saves me a long drive. I've read that you're suppose to use half strength mix. But when to start and hpw often?

hi all read this comment on the old cached overgrow "superbud - all normal nutes and additives can be used with it all except peroxide-based products!" Question 1 - is this correct? (my understanding was that H202 i.e. hydrogen peroxide such as oxyplus, should not be used with any oranic supplements. I thought superbud wasn't organic) Questions 2 - if this is correct, would it equally apply to other similar flowering enhancing hormones such as sudden impact, rockjuice, quick turn etc (ie paclo based products) or is it only 'superbud' Thanks
