Gelato - Hydro First Grow

Using four 5 gallon bubbleponics buckets with a top feed and gravity fed reservoir. Top feed with gravity fed reservoir circulates a flow to each plant of about 5 per hour. Each bucket including reservoir holds about 3 gallon making system 15 gallons. Geminated seeds directly in the rockwool in its present container. Started with store bought drinking water and had to add Cal-Meg, now am using well water and need for Cal-Meg has lessoned. LST has been challenging. All growing better than expected. Growing in a custom L shaped grow room 5x10 + 5x8 (about 90 square feet area), along with other plants.
