Hi Arnold, Are you using the Agromax T5 light bulb that is 4 feet long? How many of them to you have in your fixture? And how many total? Finally, how high do you have them above your plants? Do you use a light meter to help you adjust the height for brightness, lumens?

On whenever the sun is up. Rimmer suggested not letting them run into night time and I think it has helped. Plants need a dark period.

LEDs or something more on the heating side? -- Martin (pronoun: he) ---------------------------------------------- Southern Germany Likely zone 7a _______________________________________________ pbs mailing list pbs@lists.pacificbulbsociety.net http://lists.pacificbulbsociety.net/cgi-bin/… Unsubscribe: <mailto:pbs-unsubscribe@lists.pacificbulbsociety.net> _______________________________________________ pbs mailing list pbs@lists.pacificbulbsociety.net http://lists.pacificbulbsociety.net/cgi-bin/… Unsubscribe: <mailto:pbs-unsubscribe@lists.pacificbulbsociety.net> _______________________________________________ pbs mailing list pbs@lists.pacificbulbsociety.net http://lists.pacificbulbsociety.net/cgi-bin/… Unsubscribe: <mailto:pbs-unsubscribe@lists.pacificbulbsociety.net> _______________________________________________ pbs mailing list pbs@lists.pacificbulbsociety.net http://lists.pacificbulbsociety.net/cgi-bin/… Unsubscribe: <mailto:pbs-unsubscribe@lists.pacificbulbsociety.net>
