Looking for any advice on growing G.D.P. It would be in hydro, G H nutes, 1000w. Does G.D.P. like it hot/cold, max ppm, hows the strech after 12/12, things like that. Any help will be greatly appriatated.
I grow a combination of GDP and Purple urkle and I use 2 : 600 Watt HPS for both Flower and Veg. GDP can go up to approx. 80F in the grow room with no problems. There is almost no stretch in GDP and you will get like 1-2 inches max. I use cutting edge solution with a PPM Of 1200 in veg and like 1100 in Flower. Good luck and don't expect a huge amount of purple or anything like that.
the g d p i have streches a little but you have to tie the branches up with mine have to the buds get way to heavy to hold them but worth it. good luck o yeah mine liked a lot less nut than my other strains
