First Grow Ever

Dear Me, I had a Growers Nightmare, An Equipment failure around 21th of Jan,24. My 3X3 Mars Hydro Kit is IMPORTED from United States. it comes with a pretty powerful grow light FC-E3000. But Unfortunately it broke only after 1 weeks of usage. The Rotating knob stopped responding to dimming function. The push button only turns lights OFF/ON. And without having the ability to control the Light intensity I was left with nothing but 100% light, 400+ PPFD and 25+ degree Temp in my Grow Tent. Hence I Disconnected the Two of the Centre Light bars and Increased the Height to maximum at about 1.3 Feet from plants. This at times was showing between 230-300 PPFD but it now it's back at showing 400 here and there. At the very least the tent temperature is 23-24. I Contacted Mars Hydro notified that I'm in different Country and that I'm helpless and I can't basically send you the Unit for a replacement since I'd killing my plants at that point so please either 1) sell me a new controller stand alone unit to my country. I'll pay upfront. or 2) send me new unit and I'll send back as soon as fresh unit arrives and I swap the malfunction unit. I'll bear shipping cost upfront for both ways. But it's been like 3-4 days no conclusion we're still figuring out and yet to get to any conclusion. Hence I ended up placing order for a AC infinity 6 inch exhaust fan which comes with AC infinity 69 Pro controller( a separate unit that can connect to Mars hydro Grow Lights using RJ45 Cable Type B Connecter). It's cool how just one thing can add a whole Semi-Automation to Grow Tent Environment. Not gonna lie I did thought at this point that I had in fact made my tent buying decision in a jiffy without looking at all the other options. I hope Mars Hydro Fixes it provided that I had invested my faith in them with my money at around 1200 usd( Tent cost about 600 USD + about 600 in Shipping and import fee). Prepared Cal-Mag Buffered Coco-Perlite Mix for Coming week. Plants are already on a Light Feed Schedule with a 3 Part series by General Hydroponics. 1st Week Nutrients Diet Per Gal Water 2ml CalMag 1 ml micro 1 ml Grow 0.5 ml Bloom Ph-6.1 TDS - 277 UPDATE : 4 February : - I learned First week starts "After" the Cotyledons when first true leaves show up. Which means I've been actually in my first week only. Putting an end to my anxiety over my current plant sizes. Also, Mars Hydro replied with a humble gesture and decided to replace the dimmer at no Additional cost, They told me I could keep the faulty unit which means I don't need to spend money on returning it. and they're directly shipping to my country without any extra fee (a cherry on top). I'm yet to get the tracking but it should arrive at the very least sometime before I hit the Flowering. My first week plants look somewhat healthy despite a little light stress in the early stage. Although the Plants heights not been upto the desirable min. so far which is mostly because light was throwing too much ppfd in the early stages. Stay Tuned as i complete the week 2 on 10th of feb for these Baby Auto's.
