He said he was using MG Moisture control. And dont start that "MG Soil sucks" bit. Ive used all of the MG Soils and As long as you keep Ph in range it works beautifully. MG Soil (except the Organic) has a Ph of about 5.1-5.5. Water with 7.4 Ph for first 3-4 waterings then change to 6.5-6.8 throughout unless adjustments are needed. The organic MG, In my experience, is usually in optimal Ph range and needs no adjustments. Also, a good sign that Ph range is not right, is seedlings having purple stems. Purple stem on a seedling is common to see even with experience growers, but it IS NOT normal. The moisture control MG Is my least favorite of the brand specifially for the reason that holds moisture abnormaly long and can sometimes lead to noobies overwatering, as was the case when I used it.if your girls are getting yellow tips and ur just watering,it might be the type of soil. what kind of soil
actaully, the cheapest 400 watt hps ive seen is about $100-120.Nice Setup blackkmask. well done.. but if im going to do something like that I might as well buy a 400w HPS with a ballast , would come down cheaper.
and trailerparkkid, I'm using Miracle Grow Moisture Control potting mix... I know... not the best, could be the nutes in the soil doing this, or I may of had over watered them at the start... I will buy foxfarm soil for when I transplant . Hopefully the plants will last until then....
