i've used perilite before and it def did not hurt the plants, but now i am using all soil nothing else.


is this totally n00b?

Not really you will only end up with less airflow to your roots but people plant outdoors all the time.

you should of put peralite in the soil...but what you did is not gonna kill them or anything...peralite would of just made the soil better.....

some vermiculite woudnt hurt either

Yeah 100% soil is just missing a few things that make your plants life easier.

Careful not to overwater, by this i mean not too water to often. There is no perlite in you medium your soil should hold water for a long time.

ah ok. yeah


to 1st poster, growin indoors btw.


but yeah when we used perilite i noticed the whole drainage aspect...good stuff.


really hopin this grow will go alot better, just doin 2 seeds from amsterdam (ice...looks stinky)

thanks for the input....



not having perilite/verm isn't going to raise chance of rootbounding is it?

It's actually a very smart way to go, but, you do need to know what you're doing and adhering rigidly to a wet/dry watering schedule is going to be very important because without the 'safety net' of perlite to assist drainage it would be very easy to over water your plants.

There are two different schools of thought on adding perlite/vermiculite to your potting soil. First, most newbie growers are advised to add them up to 30% of the total volume because it makes watering much easier and more forgiving of mistakes because the perlite helps soil aeration and drainage and the vermiculite helps water retention.

Second, more experienced growers reduce the amounts of perlite/vermiculite to their soil mixes because 1) they're more experienced at understanding the watering requirements of their plants and don't need that 'safety net' and 2) reducing the amounts of perlite/vermiculite to their soil mixes means more soil is used, which means more nutrient content of the soil is retained which means less nutrient feeds in the feed water are required. Particularly important when using chemical/mineral based nutrients as these can build up to toxic salt levels which then require flushing. The less nutrients you have to use - the better the end results will be, as the plants will grow more naturally with reduced levels of chemical/mineral nutrients.

actually, if he's using 100% soil, vermiculite wouldn't do anything but retain more water... so unless that's his intentions then i wouldnt advice adding vermiculite into the soil now
