Kushandisa kaviri, kuwedzera kana kudzoreredza, gadzirisa zvakasununguka nzvimbo yemwenje yemwenje kuti iumbe PPFD yakasiyana (photosynthetic photon flux density), nzvimbo yekuvhara yakasiyana uye tsoka.

Mushure mekuwedzera, iyo shoma yekuvhara ye1000W ndeye 6 ne 4ft.

Mushure mekuwedzera, iyo shoma yekuvhara ye730W ndeye 4 ne 4ft.

Chiyero chakakwana chechiedza tichifunga nezve kudhirowa kwemvura uye kushanda kwayo

~1500+ umol/s pa 5'x5' nzvimbo

~1100-1500 umol/s pa 4'x4' nzvimbo

~600-850 umol/s pa 3'x3' nzvimbo

~275-375 umol/s pa 2'x2' nzvimbo

Iyo yakakwana yekuvhara PPFD yechirimwa nhanho:veg:300-600umol/m2/s, ruva:600-1000umol/m2/s
