don't now for sure when you need to transplant them but you will see . when plant is about 15-20 cm high .

as for myself . . . i never transplant them . I germinate my seeds and put them directly to a pot in witch will they grow to the end !

Why bother with transplanting , make your growing easier !
DreamerGirl7 Reviewed by DreamerGirl7 on . Photo of 1st plant I planted this on 11/12, as of today it looks like this. Should I be worried? It doesn't appear to be growing up anymore, but it is growing bushier. My set up includes 2 40W/3400L T12 CFLs & 1 40W/2600L CFL in a closet painted white. The plants are almost touching the CFLs. Temp 78-80F. Crappy soil from Home Depot. Rating: 5
