Hey guys so a family member is starting his own garden and is wondering if he should use T5 lights for veg and hps for flower or if he can use Hps for both... I use a t5 for my veg but he’s doing it on a bigger scale. What type of lights and at what wattage are you guys using for veg compared to flower??
As for wattage and intensity, It sort of depends on your goals. I like to hit them with as much intensity as they can handle in veg if I want them to get big fast, but Ill keep them under T5 if I want to keep them small for whatever reason. I usually start clones under T5's in tiny 2"x2" pots until they have a good set of roots and are actively growing, then after I transplant into bigger containers over the course of a week I'll go from 400wMH, to 1000w MH and then veg for a couple more weeks under that. Then flower with 1000w HPS.
The more quality light they get, the faster they grow. But again, only if they can handle it and the feeding is dialed in.
