no i have finished 3 complete runs and i am learning from each one....by tweeking i am going to try straight coco as Weezard has highly recommended it as he has very nice LED grows and learning that you don't need to water as much...so a learning process but my yields have been very close to what i had with 1000w HPS...the only grow that i have not surpassed was the ones i did with both HPS/LED when i first used them as supplemental lights but i noticed how the plants leaned to the LED's and not the HPS even though i had new bulbs in.....so i took the leap of faith and jumped....and there is no going back in my mind it is the best decision i have made :thumbsup:
