Ok, me too being a very curious individual to the LED world, seeing the Supernova LED advertised like crazy in magazines. I took a shot and purchased the 270 Watt Supernova LED and lucky for you,am running my first test for flowering starting Tuesday. I have vegged many plants with the Supernova LED, however I just got slammed with a huge load of clones which sadly out of the bunch I can only keep 16 because size of the room. The good news, because of the misfortune of losing the remainder (thanks to Spider mites setting our flowering females back), this gave me an opportunity to test the LED for flower which I have always wanted to do. Only set back is I have CO2 in my main flower room, so a huge draw back will be that these under the LED wont have any because I had to split my Veg Room. They will be grown using an Ebb and Flow system and GH Nutes. As I stated previously I have used the LED on Vegging plants and it works extremely well and hasn't let us down. Obviously in doing research on the Supernova, I searched everywhere and couldn't find any valuable feedback at the time when I purchased it about the light not performing. I seen YouTube videos of people saying I got "X" amount of ounces but never seen a growth through a cycle or read a grow journal on one. So I will post on this page 2 Flowering cycles of the 270 watt (advertised to put out more lumes than a 1000 watt HPS in a 5X5 area), first without CO2 and one with. This will help answer more questions. Only draw back is this first crop has a variety of strains, including: 2 Diamond OGs, 3 Purple Kush, 5 Sweet Island Skunks, and 6 Chem Dogs. The second batch will include: 3 Purple Kush, 5 Blackberry Kush, and 8 Diamond OGs. In the backround of the first set you will see a "kush" plant in soil I which will flower as well and has been with them the entire veg cycle because I got it as a seed. In the second you will see a Blue Dream plant I picked up as a clone, and it will start with the 2nd group. Hopefully this answers a lot of questions, honestly I am not hurt if it turns out the way it is said to, not produce nearly as much as HPS. But hey if the results are the same or close too, it maybe worth trying to save on that killer electric bill. Either way I know this kicks ass for vegging and I can stand by that, because I have turned many growers to this just by seeing nice bushy stocked mature plants by using it just for that. I will post picks on my home space here as well as try and load them on the thread. Enjoy!
