      Todays effort. All good apart from that "Yorkshire Salad"  looked on the interweb and depends on how far south Yorkshire really goes  We put onion, Lettuce, cucumber, mint, malt vinegar, and sugar to taste.

      @SubutaiThanks for the reply and advice! I will bite the bullet and go in for a six inch system, any experience with RVK filters and fans?

      In my very limited expierence, go for a 6 inch fan, I am currently running a Hydor 100 on medium speed, 194m3/h and its quite loud. Afaik a 6 inch fan running on a low speed will be quieter than a 4 inch fan on high speed and move as much air.   Also going by the math, you will need roughly 340m3/h assuming you are running 1 light   I use this site sometime, you just have to convert cfm into m3/h http://www.phreshfilter.com/tools/cfm-calculator

      I had similar issues this year..must have lost well over £100 worth of seeds trying to germ them. Eventually went with the paper towel method, for 24 hours, then into root riot cubes, 2 days later they were under a 400w mh that sorted them out no probs. Prior to this, id used a conservatory with no joy in growth after 10 days still 2 inches high, so i bought a 45w t5 and heat mat, again 2 inches high after a week or more. Couldn't understand wtf was going wrong.   4 weeks and a day or two under a 400w MH and flip to flower day. Paper towel method and metal halide ftw.
