Riu ,what going on has any one have any idea what 2 70w hps will do for 2 plants grown12/12.nirvana northern lights,ready shoing female ,8and 10 in tall.if you can please help,all helpful advice welcome.
I use 2 150 watt HPS & They worked GREAT! SO I would assume a 70 watt would grow in a small area. Something bigger than a PC grow box. maybe something 2'X2'X4' high maybe?
I dont think you;'d get much with 2 plants but one might do.
can u get 70w hps? anyway they will still double in height over the next 4 weeks so nows a good time to start flowering nutes. it will be ready in about 8 weeks.
