Each stage of growth during the flower phase has different objectives. The stretch, bud discovery, fattening, ripening.
Rapid growth is generally optimized with high temps and high rh.
Once you hit ripening stage its no longer about rapid growth and high vpd with maximal dli.
I like to think of trichomes as separate entities all together with different optimal conditions. Attempting to run 86F 65Rh% for the entirety will do little but burn off your entire profile and greatly accelerate degredation of said trichomes way before the plant was ready.
Lumatek 300w pro will get you 450-550 ppfd
@80cm.
60x60x12 = 43200 seconds x 500ppfd = 21,600,000 micromoles = 22moles = 22dli.
perfect for your plants during ripening. Keep temps lower and she will fill those trichomes for you.
Best of luck with the harvest.
