It's an outdoor grow so I just check the little buggers and water them by hand if I feel that they need it. No fancy systems here! Before I water I check the dryness of he soil by poking a finger down as deep as I can go without disturbing roots. As for age, they're about 3 weeks to 1 month old and unfortunately I don't own a digital camera . I actually think they needed water (they perked right up after a solid watering) as it had been almost a week without rain. Thanks for the tips guys n' gals, they're always appreciated! :jointsmile::thumbsup:
