You have a good point as well Blow I would like to address. If you have a plant that turns out to be male here is an idea to not waste space,light,or soil. Determine early if it's male before it gets a chance to really develop - if it is chop it, but don't throw it out. They say never to reuse pots & soil for two main reasons1) The plant growing in in before sucked all the nutrients out so the soil is useless2)The container could carry a disease to the roots of the new plant.SOLUTION - These males you chop had to be created with nutrients right? This is what you do - take the chopped plants & rip them to pieces(grind or whatever),take the soil out, but don't throw it out. Before you remove it from the container flush it thouroghly then remove it & mix it well with the chopped up useless plant. Sterilize the container, & refill it with your new soil mix. Set this container aside for future use as this will allow time for the soil to sort of regenerate. Water the soil as if there was a plant there. Would this not work well & keep people from wasting soil? I think so - try it.It's kinda similar to composting I think. My knowledge in that area still needs work. Getting back to light & space, well they go hand in hand. Young plants need less light so this will kinda fix itself when you remove the male because more space & light will be left for the remaining females. Any thoughts on this stuff?
