  1. I've been using the Lumii black ballasts electronic ballasts for a while now with 250w and 400w bulbs and they've never let me down. However, I'm a little intrigued by the 'super lumen' setting above the 600w level. From what I can find on the web, this increases the power delivered to the bulb by 10% (660W) which results in a 5-10% increase in output. A 600w bulb should produce 90000 lumens at rated power but could possibly produce a little over 96000 lumens assuming an increase of 7%. This would be suitable for a 1.2m grow space assuming a minimum requirement of 60000 lumens per meter squared for flower. Does anyone have any info/experience on this?
  2. hi,does anyone have any info on these so called fast versions of strains??I know the strain I am growing is pretty new but I'm currently at the start of week 8 and she is looking nowhere near ready. keeping the microscope at the ready and play it by ear.

    From the album Worzel Photographs

    Taken about 7 years ago on a trip to Skye, this shows a view from the top of Marsco looking south. A mediocre camera with a good lens (Canon 17-40L on a 400D). Google Satellite view of the area: https://www.google.c...692,9331m/data=!3m1!1e3
  4. hi people i have some extra room in my veg cabinet roughly around 40x40 in width and depth, with about 80cm height (50-60cm in grow height) i have some Sweet Seeds Black Cream Autos available, as well as a freebie Auto Seeds Auto pounder with Cheese my plan was to stick 2 in the cab, so i need to make sure that they dont grow too tall. my guess is that pot size will have a great influence on how tall they get, So what size pots do you guys recommend ??? i have 1L, 1.5L and 5L pots available cheers Gmaan
