<span class="link_user">@FOREVERGREEN</span>, 3 gallon Geopot's man! These Pineapple Express autos finish in 75 days and don't really need the extra soil. I've grown 14 FastBuds strains this way and get a gram per day/ per plant on average. 75 to 150 watts of light per plant is what you need as well.
<span class="link_user">@LockDownGrow</span>, just continue half strength flower nutrients until the last week of flower. Roughly day 60-65 for the California Snow. Then do a flush. You can check out the one I grew on my Instagram. <span class="link_user">@zanderzone777</span>
