Growing two buku's now. Both different, one looking like an indica the other stativa. The stativa is purple all over. Must be the cold nights. I'll try to upload pics because they are beautiful.
Someone said that the temp had to drop to 50....!
In the recent cold weather my temps have been dropping to 65 - 68 (and that's lower than I like for them to go).
If 50 degree's IS the actual temp needed to cause purpling, how long does the temp have to stay this low....?
I cannot imagine many strains finding this temperature acceptable....?
Most of the GREEN HOUSE SEEDS youtube GROW SESSIONS recommend temps between 70 and 77.
