Last two days dehumidifier use 3kw. From next week it will work harder probably. Week start @ 1.15EC, nutrient strength. Strength dropping every day by 0.2-0.3. Topping up tank with 1.2EC solution bring back strength to 0.9-1.0EC Girls look superb all time, Wedding Cheesecake is going to be a biggest strain in this run. Tropicana Cookies is most bushy with lots off side branching PH was stabile and move from 5.85 min to 6.2 max Light distance start at 75cm from canopy finish week at 60-65cm , PPFD levels around 650-700 trough whole week Temperature vary slightly from 23c at start off day to 26c max at some points. AC Infinity T6 extracting fan program in AUTO to kick in @ 26c Night temps around 21-23c, dehumidifier start to work at night time to bring down humidity, trying also to minimize Day/Night temperature differential Hope it will reduce starching a little bit in first three week off flowering.
