I have heard of it but don't do it myself....just grab them out of the light and skin them.

The plants in your photo look as though they are overnuted and/or their ph is off.

My 1st/2nd/3rd Grow Log Hey all - I have been quite innept at starting my own grow log, piggy-backing on others logs so I could post my pics, now that I can officially sart my own thread/with pics, I thought I would!! Lets start from the beginning... I was given 2 plants that were VERY malnourished and lacking in every department, so I took them on as a project (keep in mind, I hadnt attempted a grow in 13 years). So I read and read and read. And this is what has taken place over the last 3.5 months +/-...... Rating: 5
