<<< 1 >>> First Rays will be closed from Saturday, June 17 through Thursday, June 22. Accordingly, I am holding an early Fathers Days Sale. Through June 15th, all nutrients and additives are discounted 10%. Our automatic volume discounts still apply, as do any coupon codes you may have, and this offer still includes free shipping to US addresses. <<< 2 >>> Effective immediately, we no longer sell RO systems. Our long-time supplier has started charging tax on drop-shipments and is inflating shipping costs to increase profit, which would force me to increase my prices to ridiculous levels. Maintenance parts (filters and membranes) will continue to be available as I have another supplier for those.
