8 Weeks Glookies
76F, 55%RH, 1.3VPD
875ppm (+125ppm, raised steadily over 1 week)
6.0pH
300ppm CaliMagic, 875ppm total
Rockwool substrate achieving approx 75% dry back between fertigations. Changed from (2)2gph drippers to 6” Hydro Halo drip ring and added 3rd cycle. 5 min fertigations now occur 1hr after lights on, mid-day and 2hrs before lights off. Unknown GPM, but runoff occurs 90 sec after fertigations starts and recirculates for 3.5 more minutes. Reservoir temp high remained around 73F, so ended up coating the lid with matte white vinyl wrap spray paint to reflect a bit more heat. 24hr high for reservoir solution was 71F after painting lid. Now within comfortable temperature range. No additional reservoir management practices should be needed. Picture from inside tent is from live webcam. The black 20 gal top-off reservoir is in the back left, 6L humidifier is back center, ground circulating fan is back right and hygrometer on the lid next to the plant. Using AC Infinity 6” Inline fan with environmental thresholds programmed, but can check environmental conditions with camera remotely. Lines going in to reservoir via net cup opening are: (2)1/4” black air lines going to med air stones, power cord to water pump, pH/temp/EC probes to BlueLabs Guardian Monitor.
@Shockolateman08,
Ah, gotcha. I typically grow to 6 nodes in veg. Then top to the 3rd node, remove 1st and 2nd node vegetation and start manifolding it from there. It can be unnerving removing so much at once and starts off a little slow because of so much HST, but the control and yields make up for it later on down the road. Pre-load the first month of the veg with heavy training in the beginning and it’s smooth cruising after you achieve the shape you want with little maintenance the rest of the grow. Finish most, if not all, pruning before switching to flowering light cycle. Defoliate lightly in flower to control RH. I do note defoliate heavily. All those extra fan leaves act as nutrient reserves and extra solar cells even if they’re not getting max light. I follow this guide almost exactly https://www.growweedeasy.com/manifold
@RogueOne, no...just found seeds and started...I grew about 15 yrs ago but nothing to the extreme of techniques. Manifold training. Where and when do I start?
@Shockolateman08,
Are you talking about the hydroponic system or the manifold training method? I highly recommend using this system. It’s my first time using it as well. I have grown in soil and DWC before. I expect to use this method and system from now on. Much faster veg growth than soil and significantly more stable reservoir pH than DWC. Very simple system. I only added air stones for temperature control. You might not even need those. Lots of air for the roots with rockwool croutons. With limited space, I’d recommend a short, wide approx 15 gal tote and a short pot to maximize height available. I am using a short 2 gallon pot with 4 fertigations per day so I have more height available. Very stable reservoir temps with this volume of water. For faster root growth, it is recommended to allow proper dry back of rockwool. I got away with hand watering every couple days the first month or so before automating to prevent overwatering. Pay attention to your plant and learn how much it drinks before coming up with an automation schedule. Since space is limited, LST wide and low and switch to 12/12 when plant is approx 1/2 your final desired height (assuming you’ve picked and indoor tailored strain that grows short and bushy, usually advertised as indica) based on total height available and proper light distance.

Congratulations on the new baby. She looks good at first. Choose a good variety. For a treat. Keep doing what you are doing and ask the growing ganja gods to protect your women until the growth is over.
