Then we agree to disagree, You may be more than happy not to put in perlight and you may add just sand. But ask your self this. Does sand absorb any water or nutrients and hold this for the root system to uptake when it need it? And does sand hold air for the root system? No...... All sand will do is sit in the medium not doing anything much. It may well help a little with the drainage. But its definatly not going to solve the problem of drainage Unless he repot's and adds like 60% sand. Now correct me if you think im wrong, but sand does not hold moisture and will therefor not hold any nutrients nor does it hold any air... ( at all ). Yes these plants are vigilant and will grow in just about any shit. But for the most time If your a keen grower and you want the ( best ) enviroment for them to sit in and grow then you need to create this.
OK so a little about transplanting in to a larger pot. Firstly if your plants are in a vegative cycle then you will create more space for root formation. Larger root formation means a larger plant. a larger plant means More flower production.
So i repeat what i said before. You need to repot, And add perlight to your medium. And add clay pellets to the bottom of these pot's. This Is the best solution and don't listen to greenmonkemann...
Happy growing blunters mate....

perlite doesn't really absorb much water, and the nutrient uptake is minimal, if that's your thing than vermiculite would work much better, perlite also doesn't really hold air, as much as it displaces it,(that's why it always floats to the top when you water).
I'm not knocking perlite or saying your method doesn't work, i was just saying that fox farm will do fine out of the bag mixed with a 5lb bag of horticultural sand, or perlite, or coco fiber, or vermiculite, or crushed volcanic rock, you hit it on the nose when you said these plants will grow in most anything.
transplanting progressively to larger pots a little at a time will increase the root ball mass and as you said, increase flower production.
Almost every book, i've ever seen or read has stated the same thing.
you seem to be annoyed by my post so for that i guess i apologize...
and thanks for telling him not to listen to me, i could care less, i'm not posting for any gain.
I haven't learned anything on this site, it's standard, basic horticultural knowledge that you can get from any number of books,
yeah call me arrogant too, all i was doing was trying to help and share my trials and errors, i've had over 35 harvests in my life and over the time you pick things up....
like sand displaces less space(more root area), does better at drainage, doesn't retain high salt amounts, and helps with stability at heavy flower top-time.
So please, dan, as you said, agree to disagree but to attempt to dis-credit me would be foolish.
