Both plants were topped on day 34. At day 36 and plant 1 is looking healthier than plant 2. Clearly much bushier and the roots have gone all the way through the pot and down the capilliary matting and are now clearly spreading into the water reservoir below. Plant 2's roots have yet to emerge from the bottom of the pot.
Though I am not worried as both plants look healthy and very much alive, it's just one is clearly much more advanced than the other.😎
@Cannabrown, For the general pics I have a Canon 24-105 Zoom lens. For the close up shots I have been practicing with a set of extension tubes which seem to be working out OK.
