For anyone following this I have 4 led strips mounted above a shelf on the plant stand, 20 watts of led power. I have spider plant starts under these lights, I also have spider starts on the shelf above that gets more natural light but no led light. The spiders under the led exploded in growth in the past 4-5 days and are close to double the size of the plants without led light. These spiders are in 4" pots, planted middle of May and I have roots growing out the bottom of the pots already.
I'm going to order two more sets and add lighting to my Davallia collection.
