So I recently converted my room from soil to a custom built undercurrent system. Quality/health of my plants is definitely Much better, but sadly have seen a fairly substantial reduction in yield, will give specs of both setups and grow room to provide as much info as possible...
grow room specs
room size is 6' x 9'10"
-lighting is 3x1000w hps (hortilux bulbs) in air cooled hoods
-air exchange is 10" vortex fan for exhaust running through air cooled fixtures, and intake is 8" canfan max with a custom built air intake filter (uses filters from a central air system, 20x25... 3x particulate filters with a hepa filter at end, sealed air tight to prevent bypass)
-14k btu mini split a/c system
-90p dehumidifier
generally speaking the enviornment of the room is Very dialed in, maintains a solid 78F +/- 2F, humidity locked in at 45% in flower and 60% in veg
previous growing medium was 21x 10g pots with ~7g of soil (used 10g pots to increase the diameter of root base) with this configuration i was regularly hitting 4-5lbs dried/cured n tightly trimmed flower.
the new undercurrent system that ive switched to, consists of 8x 13g buckets & 13g res/control center bucket, using 3" piping between the buckets & reservoir, a 1/2hp chiller, 110LPM air pump, 3x airstones per growth site, and 2 magdrive pumps for circulation (500g/h and a 250g/h) the 500 is setup for direct circulation feeding into res, and the 250 feeds into the chiller n then back into res. water temp is very consistant at 66F
nutrients for hydro setup consisted of
gh floranova bloom
H&G roots excel
H&G multi zen
GH kool bloom liquid
Grotek Bud Fuel pro
GH kool bloom powder
GH floranectar
was able to hit as high as 2300ppm before any sign of nutrient burn and adjusted accordingly throughout the cycle
final yield with the hydro sys in same room was a sad 2.5lbs
i will full out admit with switching to a new growing style i was not experienced enough to lollipop the plants properly and ended up with a canopy around 30" in depth, which is Terrible... even then tho... does not account for such a massive drop in yield
Im not about to go back to soil as i much prefer doing hydro at this point and aside from a low yield, quality is Much better. so basically, someone, anyone who is able to help me get back on track, plz comment! ive invested far to much at this point to turn back now, the potential is there, the equip is there, seems im just, overlooking something that im unaware of
