Completed HPS from week 2?

[Shrederr]

So im running some blackberries and i wana start a prepretual, i have room in the tent so i wana give them 10 days under cfls or cheap white led then move into bigger tent with 600 hps.. im not worried about light stress, ill keep them far away, but growth wise, what should i expect?

Cheers

When i use hps (winter time) i use it at 600w from start to finnish.
I start seedlings with the light at least a metre above.
Then slowly lower i didnt experience any unwanted stretch and growth was always good mate

Ty woody mate i love the 600 mh work in my current grow its day 30ish and plants are 6-7 cm tall!
Should i expect normal cfl-like growth?
And what about vegging photos with 600hps, any difference? Tnx alot

Im not really sure what normal cfl growth is like to be honest mate!
Only ever used hps( i always use a dual spectrum bulb start to finish) and cob/quantum board led.

I would expect them to have stretched a bit higher that 6-7 cm by day 30 though mate. Normally between 1-2 feet 30-60cm

Grown prob close to 200 autos now but ive never grown a photoperiod

Thanks mate I guess I'll just stay with the HPS maybe put some T5's or white leds just for more spectru,

That's exactly what you should do, keep with the HPS, but further away than normal until they are large enough.
