      2c worth / geek mode:....  Lumen's have very little use in measuring a lights usefulness for growing ganga, as they only measure how bright a bulb is to the human eye, it is not a scale of efficacy when measuring production of par, for this you need a par meter.    Cost you a dam sight more than a lux meter tho   I think the only use you could have is you bought the exact same make / model of bulb, then you could measure deterioration.  A different bulb could show different weighting measures of lumen, but similar par.

      I’m currently on week 2 of flower with 6 stardawg girls. I’ve been using canna nutrients from the start and have been following the guide Almost exactly, I’m currently feeding at EC 1.7 but I’m reading that this is too high?? They seem to be happy but now I’m worried about bumping the EC up which is what the guide says to do as you get further into flower. Any tips or advise would be much appreciated

      Im using a similar size tent and im using a 250w HPS, 400w would be too much for that space.
