vegging four weeks is fine
You can veg longer or even less that said 4-6 weeks will see you good.
The best medium is the one that suits you best
Personally I use soil from the hydro shop not the garden centre as the hydro shop stores there’s soil inside away from bugs where as the garden centres store outside and you can end up with a bag on bugs in your soil. I use
bio bizz almix.
With soil you don’t need to ph your water the soil it’s self buffers the ph
It’s a total waste of money buying co2 bags anyone who says otherwise has no idea of how much co2 you need to make a difference
Co2 is not needed
Co2 at the right amount of ppm does help plants grow faster however it also comes with it own set of problems and as everything is speed up you get less time to rectify any mistakes
You need tanks of co2 the bags are there to real in new growers and anyone pushing them on you in a hydro store is more interested in thier cut than your grow
Unless you’ve a closet or a basement it’s better to use a tent. You can use a spare room just rem you will need to blackout the windows and that it’s self can have neighbours wondering
You’ll have a very bright light and smell to deal with best to put them in a tent so your not blasting light out for everyone to see. That plus you want to keep the plants bug free and clean.
The carbon filter doesn’t only clean the air it also helps with airflow witch you need and to stop the heat/moisture ( humidity) building up
Fertilisers
The best one is the easiest I don’t like
bio bizz nutes as they have too many bottles of this that and the other many like it so I am not saying it’s no good.
What you choose is really up to you tbh there’s not much difference between one bottled fert and another bar its price.
During seedling stage we use none there will be enough in the soil for it to get established.
When the plants established and is ready to feed during the veg stage you’d want a grow fert. The number on the bottle like 7.3.3 reflect what amount of npk is in them. The first number is Nitrogen you want a higher n in veg than you do p&k
When your ready to flower for the first two weeks keep using veg fert after two weeks have passed and your ready to switch to a flowering fert you will want a fert higher in p than n or k roughly guide would be 3.8.4
Most bottled ferts have a chart showing the amount to use it’s normal practice to follow the chart at a slightly weaker rate than they say
I use guano witch is a dry fert however there’s no chart still I do find it very easy to use.
All this was will sound complicated with terms your not used to ect really it’s not once you get your hands dirty and have everything set up.
