Thanks again Weeze

I can stop looking up the ingredients of dechlorinators now !

I ordered PH kits for water and soil so i should have those figures next week (shoulda had them at the start !).

I want to move the light closer to the plants but the heat increase is mad.

Right now the crowns are 10" below the bottom of the light, i balance the thermo/hygrometer across the plant pots so it's at (or just below) their crown-level and the temperature is 32 celsius, 90 farenheit ! And the humidity is 25%.

If i touch the CFL after a few hours use, it is ok to touch on the underside but too hot to touch for long at the top.

I'm thinking either a fan to blow over the light or maybe a glass sheet between the light and the plants, i've just realised I'M RAMBLING !

Ooops ! Went off-topic there ! So easy to just start writing down all your thoughts in these posts.

OK thanks again,
