Sweet Tooth autos / LED / Soil - First Grow & LED experiment

I actually began this an experiment with low watt LED lamps and bulbs, plus a simple soil setup with leca and perlite.

So first, I used a 12W bulb for a few days..



That bulb got overheated or something, would never turn on again, so I switched to a 15W bulb which was even slightly smaller..



That didn't give quite enough light as I know it. So i bought a 90W UFO to couple with that 15W bulb (they cover slightly different frequencies anyway)..



I try to keep the humidity between 40%-70%, the temperature is constantly between 21-24C, I adjust the PH value of the water with lemon juice to ~6.5 and have a fan on a timer on a 18/6 cycle along with the lights. The fan only runs every half, on every hour, during that cycle. I stress them off completely during night. No light and no wind for 6 hours.



Wow, it may be sunny tomorrow?! ..This is the status of the plants anyway..



Any suggestions or feedback to the setup or the plant(s) would be greatly appreciated.

Ide say your plant has no complaints so just keep doing the same thing you been doing.
Good job.!

That sounds good. Thanks. All I know about how they should look and act are from vids and pics, so that's good to hear.

Does anyone know if I can use orchid nutes for the vegative phase? The ones I got a hold of are: NPK 2-2-2.
