How about 75% or it just needs to be run at 100% see the main reason i had it at 50 is to save some money on electric bill. So should i go ahead and run at 100 and adjust the height of the hood.
See i germinated my seeds before i even had plan on getting some decent soil so I got Miracle Grow potting mix and mixed it with like 50% top soil.
OK, first off I'm pretty baked right now
so bear with me, Tis the time of season
anyways, I was told by a very reliable source that running your bulbs below (dimming) or even above (SuperLumens) their rated wattage not only wears the bulbs out much faster (and the lumen maintenance of HPS/MH already sucks) but also puts off a different spectrum than the bulb is originally rated for, these are the facts, you can do it and it works but you'll be replacing bulbs more often and running at different spectrums, if your going to do it I imagine running at 75% would be best, but I was told, again by a reliable source, to run at 100% and raise the lights if needed, as for Miracle Grow, WHY? There are so many other better soils out there, my local hydro shop tests the soils they sell and recently VermiFire and Amazon Bloom came out the best, VermieFire already comes premixed with perlite so its ready to use, anyways, MG works great for tomatoes and flowers but for cannabis flowers, get a good quality potting soil and add 25-35% perlite (unless your using VermiFire that is), if you take care of your plants needs and give them the best you can, they'll do the same in return, whatever you decide good luck and keep us posted.
