Na. I had them outside in full sunlight during the day, then put them in my bathroom at night, and used the regular lights in the bathroom. lol. It worked though. And when I learned about topping and fimming, the romulan was huge so I just let it go. And I also used miracle grow soil with the pre added nutes and its moisture control too. the soil is awesome. and the nutes are miracle grow all purpose for vegg and miracle grow bloom booster for flower. not much people like miracle grow, but I love them. I'm doing great with it. And about the LED, That's awesome too. Works pretty good for flowering, I would recommend 2 for flower or 1 of the bigger Wattage blackstars. But on seedlings and vegging dude! Its crazy. They grow so fast.
