Top a few and don't top a few, see what works best. Some strains respond very well to topping, others it reduces yield. Make sure to keep one clone as a momma to take more clones from, that way you can grow the same thing out a few times and perfect your technique to maximize that strain's potential

Really nice looking room man. I see your light has the fittings for air cooling, does it have the glass in it already so you can connect a fan or is it open air right now? And are you planning on connecting a fan across it? I have a cool tube on my 1kw HPS and it helps a lot with the heat. I can't wait to see that room full of giant nugs :dance:
