No pics of germination process (paper towel method). Went well as always. Have grown this strain before and was pretty happy. Looking to optimize certain aspects this time and will attamept to grow two plants in my small grow box. Probably trying a Nebula mainline, not sure yet.
Light dimmed to 20%, PPDF Meter with UNI-T reads 250 PPFD under dome. Water PH'ed to 6 with a Base EC of 400. Added some CompoComplete to EC 800. VPD roughly at 0.8.
So far so good. Increased lighting to 40 DLI, lets see how they take it. EC at 550. Still fertigated once a day till there is ~200ml of drainage, 1h after lights turn on.
Transplanted to ~10l pots yesterday. First topping will happen soon, probably 1 more node, so ~2 days: Raised EC to 1250. Lights are still dimmed to 40%, readings are roughly 40 DLI with 20h of light, therefore little vertical growth.
Still debating how many tops I should go for in the small space. Might top twice for just 4, do a full mainline/manifold with 8, or keep nodes 4 and 5 and top twice for 6 total nodes.
Topped at day 20. Some crinckling on the larger fan leaves - looking for now. Decided on doing 6 Nodes per plant. So I left Node 2 and 3 and will top the new mains once more, probably at the end of week 4.
Repotting and topping did apparently stress her and growth slowed down. Relatively low temps during the day (21°) after I decresed light intensity might add to it. Also needed to remove a pair of leaves, which were basically growing into the ground.
So as a conclusion for myself: ~45 DLI in the first weeks might work, but at least for this cultuvar within the given environmental parameters possible in this setup, it's pointless. Lowered back to around 30. Will top the upper nodes once again in ~2 days for a total of 6 per plant and likely flip her at the end of week 5, once the space is a bit more filled out. Will experiment with an automatic watering system next weeks.
Both plants topped again. Looks healthy, though grow is relatively slow. Temps have fallen to around 19-20°C during the day, so no mystery here. Should be easier to get higher temps during flower, as 100-150W in that small space will provide some decent heat. Difference between day and night temps might be on the higher side, so I do expect some purpling, just like the last plant did in that space.
LSTing is kinda hard, due to the very compact build and quite hard stems.
Also starting to build a automatic, timed ferrigation system.
Again, looks healthy, but grows slowly. Will flip tomorrow, temps should be much better with 100w instead if 45 and slowly rising outside temps. Automatic watering will also start tomorrow.
