Stepping up my game

Hello! First diary, let's gooo! After 2 successful soil grows (with advanced nutrients), I thought it's time to step up my game; mostly due to the fact that I have to leave for 8-10 days 2 times a year and the only 4 month window without july-august is nov-mar. What's the plan and what is new to me: - 5x5 tent (150cm*150cm) - 9 fastbuds autoflowers in 15L (4gal) pots - 70% coco - 30% perlite (new) - high-frequency fertigation (new) (150L (40gal) tank + 3000lph (800gph) pump + 9 * 6" Hydro Halos) - Terra Aquatica nutrient line (new) + taking care of EC (new) - I want to top all 9 (new) - Scrog with a very low height (like in the 2nd photo) - grow them horizontally and try to fill the holes as much as possible - lst to help with the plan above I also mostly built everything as you can see; each pot drains into a tray that's on a slope; I drilled a hole in the dray where I sealed a filter washer and a tube that drains into a bucket .. so I have 5 trays that drain into the same bucket, where I have a small pump with which I push the runoff into another bucket that's outside the tent; this way, the bucket from the inside, stays inside. I am a bit afraid of this, but here we are! so far, 7/9 are out of the medium, one I think should pop-up tomorrow, but I think that one Amnesia Zkittlez out of the 4 planted, will not germinate; luckily, I had another one for backup, so today it went into the glass of water and tomorrow it's in the medium; hoping to not loose the herd. I will update as soon as I have news What I did so far with the girls - each seed was placed into a shot glass with some tap water; all shot glasses went onto the same tray, into a small cardboard box (to keep dark), along with a thermometer; this box was placed at the edge of a heating mat designed for seedlings .. I moved the box until the temp settled at 25 celsius (77 fahrenheit) - after 18 hours, I tapped on the seeds, they went to the bottom - in 2 hours they went into the coco update 14 nov - 8/9 are getting out of the soil, trying to stand up and shed the helmets - 1x Amnesia Zkittles does not do anything; yesterday I soaked my last seed of Amnesia and it went into the pot an hour ago; I hope she will rise, catch the rest and have only a 2 day-delay; the initial seed is still in the pot, just nothing happens .. I placed the 2nd near the 1st, I hope one will crack - will probably call tomorrow day 1 update 15-18 nov - the seed planted later is now up with the gang, the first seed still did not crack, I removed it, and call it a loss; first seed that fails to crack out of 20 fastbud seeds - I started nutrients, according to the Terra Aquatica feeding schedule; 0.3 EC, root booster and trichoderma (trikologic at 0.1g/L), 100ml per day around the seedling - thinking about doing 1L in each pot with only root booster and trikologic, no nutes (and away from the seedling), but will probably wait a few more days .. just so the roots will have an easier job in the next weeks
