Maiden Voyage

A big week this week commencing Friday 15th January. Not sure what height the girls were on 15/01 but the pics on 15th and 18th show at least a couple of inches. By the time I started LST on 20/01 they ranged in height from 7"-11". Main changes this week: 1) The seedlings moved from the small pots to the final 10l pots. 2) Changed the 130w CFL to a 600w dual spectrum HPS fed through a ballast set to 450w. I started the light around 30" above the canopy but realised this was too far away and lowered it to 20". The heat improved very favourably i.e. jumping from 20-22 degrees during the day to 28-32 depending on whether the central heating is on. 3) Started nutrients (see pics) according to manufacturers dilution recommendations. My routine is water/feed on alternate days. Adding the nutrients in a one feed on/one feed off schedule. 4) Included a monkey fan in the cupboard. Started off on a 30mins on/30mins off schedule over 24 hours. I then switched to continuously on during the 18 hours of light and 30 mins on/30 mins off in the 6 hours of dark. 5) LST - I drilled holes in the rim of the pots at 12, 3, 6 and 9 o'clock. I used garden twine to tie the plants down in the 6 o'clock position (see pic) wearing disposable latex gloves. They are gently bent to avoid damage this week. My intention is to rotate the position every two days (on feeding days) going clockwise from 6 to 9 to 12 to 3 etc, etc.
