These pics are from today, 53 days. Just swapped light today from Mars hydro ts 600 to Mars hydro ts 1000. I used a ppfd meter app I downloaded to my phone to check light levels and determined that having the light set at 75% won't be overdoing in. Fed 3.5gs of megacrop in 1 gallon water then split between the 2. Humidity at 28% and 73°f. I'll try to remember to post in here as well as my grow journal so updates are easier for you to see also Inkaddict$. Happy growing everybody!
