temperature is right on the money. have the fan. and a complete change every 10 this young? Cant i just add water at early stage?

Also, to change PH, should I add more grow to lower or just PH down.
NwoodE Reviewed by NwoodE on . Hydro/Bubbler question My current crop is 4 1-2 week seedlings in 5gal. bubble buckets. Seedlings are HighGradeSeeds mix pack. I plan on adding 2 (other grow female) clones to this setup once they root. I vegged them under 80wt floros 1-1.5 weeks. I just put the eldest seedling under 300watts hps at a distance of 3 ft. They are in pure hydroton. Rating: 5
