Arjan's Haze #3

Haven't grown in years but recently a good friend developed M.S.....I now felt it was time to help! Germinated 2 x Arjan's Haze #3 seeds from GreenHouse Seed Company , however only one has popped to date. Maybe they are old seeds... , I won't give up on the other one lol. My first viable seed popped 3rd Aug 2020 after 72 hours with a tap root about quarter of an inch long.(6 hour soak in water and then paper towel method) This has been carefully planted in a well watered and drained 10cm pot. I am using Plagron Royal Mix & have pre soaked the soil in a Plagron Power Roots solution. First time growing under LEDs , a 1200w Philzon Dual Switch, I previously used a 300wCFL and a 400wHPS with good results , but have an open mind on the LED front. Will update you all in a week as to how my seeds / seedlings are progressing. Peace , Love and loads more music. Update , have a 1" seedling now bathing in burple light 😀 The other seed didnt pop. I dropped it into a shot glass of water.... it sank.... I removed it from the water and gently squeezed it until it cracked a little now back under the damp paper towel, only time will tell , I am impatient at the best of times, other than giving said seed a few more days ,at which time I reckon she's a gonner.
