Gabgrow Happy to share this black tuna grow. Seed was planted directly in substrate. I'm using a 3,5L plastic pot for the germination phase + early veg. Planning to transpant it to a 15l fabric pot a little further in the vegetative phase. Roots booster will be applied by the end of this week, when we will start feeding.

Gabgrow Not much on this first week besides an unusual long stem on this one. Sice I'm going to transpant her I'm not very much worried about this. Yesterday I applied the first row of nutrients with a broad spectrum organic root booster. Next week we will be implementing solo amendments like liquid humus, alg-a-fish and bokashi.

Gabgrow Not much on this week besides a steady early vegetative growth. Planning to transplant next week. This week I applied the first nutrient feeding.
Happy growing to everyone!

Gabgrow Transplanted this week to a 15 liters fabric pot. Not much this week besides the transplanting and some significant vertical growth. She also started shooting some side branches. Next week I'll start low stress training to promote side growth, since this plant will have to manage a long vegetative period while I finish gelatos on the other tent.
Still deciding if I'll top her or try some other HST technique.
Nice growing to everyone!

Gabgrow This week we applied the first technique intending to increase side branches growth. We did some selective defoliation paired with some leaf tucking. Regarding the feeding scheme, the only change was the removal of the root booster. Not much besides that, waiting for it to get fully rooted to transplant it to its final 50l fabric. I'll try a longer vegetative phase with increased training to manage the canopy coverage for 80x80 on the flower phase with only this plant. I'll keep you guys updated, but the idea is to create some kind of monster plant. Wish me luck.
Good growing to everyone

Gabgrow This week I applied some Defoliation to promote lower branches develpment. I'm still deciding if I'll try to produce some clones on this plant or if I transpant it to a bigger pot and try to run it alone on the tent. Probably second option since I'm not having many sucess on cloning 😿. Anyways I'll have to wait the harvest of the AK-Auto from my other diary before such decision have to be made.
Happy growing 2026 to everyone out there!
