Distance for600 HPS off canopy


Recommended Posts

Hi crew

If you can control the heat of HPS (I have a 250 isomax extraction fan and 2 fans going with cool air coming from low) how far should you put a 600 hps from the canopy ?

Like is it better to have it still 60-80cm from the scrogged colas or is it better to have them 20cms ? I have had them within that 300mm and had no burnt buds or leaves surprisingly but haven’t really noticed a huge difference like harder nuggets yet . I think if I keep it raised like I used to before I got the isomax then it spreads the light further across the canopy so keeping it about 40- 50cm away at the moment

 

Just wondering if there was a preferred height or not

 

Also I have a Durban poison still have a few weeks to go but all the buds are really fluffy - they’ve been under 600hps the entire time , maybe I’m just getting to excited to harvest early ... I’ve never waited for Amber triches before I usually leave them at milky - and I’ve had issues with mites and bud rot on last 2 grows so harvested to limit any losses ... though I’ve heard if u wait the last few weeks can really Dense up the buds is it that noticeable ?

Also, the buds in the bright bits are normally heaps denser than those on the outskirts, buds like bright light.

Yep ur right midlife I’m gonna get one - how often do u replace bulbs ? I’ve done 3 grows with the same ones about time to replace ?

I had a cheap growlush which lasted about 2 grows and the gavita already for about 6 or so. But I use a mix of mh for veg and hps for flower. Love how they thrive under the mh during veg. We'll worth getting a mh if you don't already. I change to the hps about 2 weeks after flip to 12/12. They reckon it helps with reducing the stretch
