couple of hydro questions need answered

i have an aerogarden started and just had a couple questions

- is it ever too early to start adding nutrients?
- would bigger seeds grow more efficient?
- when am i going to have to determine its sex?

any advise or tips for a begginer would be awesome

Yes, nutrients should be added at 300 ppm when the plant shows it first true sets of leaves.

Bigger seeds are kinda a yes and no answer, you do want a full developed seed and usually the bigger ones are maybe better developed.

You can determine sex a number of ways, wither by taking a cutting and rooting it and sexing it, of waiting for preflower which will generally apear after 30 days in veg.

Or you can flower the whole plant, and revert it to veg, although this method is highly unpractical..

little,root,kind,keep eye on them 24/7 have a pair of twerers and a bread tie,take off plastic off the top use to adjust baby seed,(rockwool)not deep at all the sex yea , biger better!

im using a spoungy like material that came with the grower is that rockwool?

Most likely, is it kinda brownish/tanish, and gritty?

they're grey but if they came with the thing then im sure they will be ok... my mom grew tulips with it before i got ahold of it : ) but the tulip roots went right through it so im sure its good

the dead root could cause a fungus or mold cause there dead,be careful!

ive used nutes and also burnt my plants am new to this but i like spend all day researching,and from my two weeks all ready use very little nutes am at 300 i burned them with like 1000ppm and 500 ppm but ill keep u posted.cant wait to get a camera so people can help me.
