Is one 30W CFL enough?

[Nonken]

Hello 420Magazine

My plan is to build a ''grow box'' where the seedlings can be the first weeks so they can get strong enough for the weather, before they will be placed outside... The size of the ''grow box'' will be 75x45x45cm where there will be one 30w cfl and 2 pc fans. But i'm insecure that it will be enough. maybe it's better if i add one more 30w cfl bulb

Hope u guys understand me, english is not my first language...

I would put more just to help prevent stretching and in the long run a couple of cfl bulbs are cheaper than a bunch of ruined seedlings.

So two 30w cfl bulbs should work?

To an extent. You'll probably be good with 2 sockets and you can double it up with socket splitters if needed. But at some point they will outgrow those bulbs if you don't move them outside soon enough.

For my current grow, I started by using two 42 watts to veg two plants.
