OK a little update: The WW and SSA are tarting to put some decent growth on now. Both are showing sex. The SMA (seedling) is now in a full size pot as all its roots were poking out of the jiffy. The two bigger girls had a small feed on Monday and are looking good so far. I'll see if I can do a pic later.
The stability of the tent is a bit of an issue. Whenever I open the door it twists the right hand panel slightly and it has tipped over this morning due to the weight of the lights. No damage, but a pain in the rear end. Not entirely sure what to do about it, as I'm at my limit with what I've spent on it. Any ideas anyone? Each panel is 4 pieces of pvc pipe joined at the corner by simple elbow joints. Any restructuring right now will probably cause me aggro anyway, but suggestions are welcome.
