Germinated two Barney's Farm LSD Fem in a paper towel for a day. Both were successful. When the root appeared I transferred them to the rockwool cube. Watering is 2 cups of solution every two days as it evaporates. Next week I'll probably start the DWC once the roots pop out of the cube. I also deemed it inefficient to power an 18-gallon DWC system for one cup per day of solution usage until they get a bit bigger. For now they are happy in a glass baking dish.
PH: 6.3
Solution temp: 71.8°
Air temp: 76-82°F
Light cycle: 18-6 (5am - 11pm)
LUX: 12,000. Light @ 40% output - 30" distance. (Do any sugar daddies out there want to buy me a PAR meter? LOLZ)
RH 65-75%
I determined they were strong enough for the RDWC system. I have no airflow control over the stones at the moment so it's 26 Liters/min via two 8" stones. A 1.2 ratio.
Water circulation flow is 380 Gal/hr. Or 15 swaps.
Pushing a nute level of 620PPM (@700)
In a week or so, I'll pop on the C02 @ 1000PPM+
I'll start topping in a day or so.
Looking good for now.
I'm keeping an eye on the right plant. It has some spots on the leaf.
All else is normal, water is clean and roots looks strong.
