Idiots guide to grow lights

Danny, what are you intending to put under lights?

Sorry JJB missed this!

Anything that actually germinates!!!

The plan was to do a test with 1 germinated seed on the windowsill and 1 of the same variety under the grow light. Unfortunately to date I have had 4 different seeds germinate therefore they are all on the windowsill!

I could have been scientific, but for some unknown reason, wasn't.   I have a couple of more advanced  red robin tomatoes the same age under lights and one a week younger on the window sill. In hindsight I should have put one of the advanced on the sill (might still do that). The window one is fine but searching for light, the advanced ones are healthy an dumpy.  Some of the chillies are unusually stretched under the lights, maybe chillies like whole light rather than red/blue.
