Veg (T5) to Flower (HPS) - How to avoid transplant shock?

[Doc50holliday]

Hey guys,

So my girl and I both had the same issue a few harvests back in regards to transplanting from the veg room to the flower room.

It seems like the change from t5's to 1000W Gavitas was just too much, and hurt the crop fairly bad.

Now, I feel my girl is over compensating and slowly raising the wattage week by week, maxing out at 750 Watts for only the last week and a half of flower.

My intuition is telling me that we're missing out on significant growth if we're slowly raising the wattage like that.. I mean we're probably at 500 watts 6 weeks into flower and then maxing out at 750 in the final weeks...

Thoughts?

D/L light meter app on phone and try to match it then raise slowly if possible. I think it's better to literally put it in the ceiling of the tent and waiting a few days and possibly lowering it than worrying about missing out on some speed of growth and putting it too close.

I kinda had the same problem and that's what I ended up doing.

Are they getting fried? If they are the onl;y thing in the tent and only take up a small amount of the canopy so far... maybe all the light energy will bounce around and absorb in the plants making it too much IR and not even light sometimes maybe have to turn down wattage, open tent wall ect for a fe days til they fill out?

Should've added this for context, but we're not in a tent.. We're in a sealed room...

And yeah, they were getting fried. That's why we're now starting out at 150-200 watts when we transplant, leave them in veg for roughly a week, and then turn the lights up approximately 50 watts a week until harvest. I want to amp them up quicker but she's afraid of frying them. I've looked everywhere for a schedule on raising the wattage but haven't really found much..

Will that D/L light meter help with this? I do have a pulse one monitor

"Lux light meter" helped me it's not "full spectrum" or whatever but it gives you a standard and casn show u hotspots, with HPS a lot of places say 35'000-70'000 for flowering but others say 10'000 and I found 10-15'000 works better than 25000 but average kinda thing having a hotspot of 20'000 might be ok overall im not really sure.

"will it help" it might, if ur like 50'000 u might want to raise ther light or whatever niot sure but like i said i had problems frying them and i raised the light and lowered it until the canopy was full

Fantastic, I did some research and I think this will help me a lot.. Thanks a lot dude.

IME its also a matter of spectrum...
with HIDs the best result i got from seedlings under T5, veg under MH and flower under HPS..
I always taught veggin under HPS its brutal for a plant...even if many do it...
