Re: Bloombox hydroponic grow "chrystal"
I think it's important to keep a constant volume of nutes in the res. I keep mine topped off with a separate res and a float valve. It is the only accurate way to tell how much your plants are feeding. If you only top off occasionally they will be drinking more than feeding and thereby raising the PPM of your nutes. Keeping it constantly topped up will let you know when you need to add nutes to the mix. I will add nutes when my PPMs get below a set number so that I can keep it in my target range.I top off every week ,sometimes every day with ph balanced water only,I never add nutes,and I have never had a problem with this, seems to me that every time i check my ppm its between the levels ,so no need to feed
