First Grow: Crystal from IGLM in a 2x2

Both plants sprouted after a couple of days. One plant immediately had some pretty fast growth and stretched towards the light. The other plant sprouted somewhat tall, but the leaves haven't emerged yet. This plant is likely going to be stunted and a slower growing plant, so depending on the growth over the next couple weeks, I may decide to cull this plant. Seeing that the leaves haven't gone out yet, but the seedling is somewhat tall, I assumed the par was too low. I don't have a par meter but I have the PPFD chart from Vivosun's website. Using the chart, I moved up to ~170 PPFD to encourage a bushier plant and to stop stretching. Humidity has been between 45-60% and temps have been between 70-78°F. Watering has been using a small cup to create an upside-down dome of moist water since I am using 5 gallon pots from the beginning. As the plants grow I will increase the amount of water used as well as the diameter of the dome's base until I am watering the entire pot.
