<span class="link_user">@Boribori787</span>, I used the AC Infinity Light (2x4) that came with my tent. I had it set to 100% and just messed with the height till I got the correct light reading. I use the Photone App for my phone and a 20 dollar diffuser I got from Amazon. Every week once it starts growing, I measured light at the plant and adjusted.
<span class="link_user">@Boribori787</span>, I used Coco, I originally used 5.8 for this grow, but would suggest 6.0. I used Grow Cups that drain on their own, I only watered very lightly- not allowing to dry out. Every Morning I watered a small amount.
