hello tomorrow i have 6 orders of 1500 duckweed and i am not sure i have enough so how can i boost the growth
 
Add a liquid iron based aquarium plant fertiliser and leave the light on 16 hours a day. Keep the iron (Fe) level at 1mg/l (1ppm).

You can also grow the stuff outdoors in ponds or plastic storage containers when the weather isn't freezing.

Well the weather is kinda cold the pobd colony is not doing so well
 
Get a shelving unit from a hardware store and put shallow plastic storage containers on each shelf. Have a light above each container and grow the duckweed in the containers. They only need to hold 1-2 inches of water for Duckweed.

how to heat it?
 
If it's in a house, the room temperature should be enough for Duckweed. It can grow in cold or warm water but grows faster in warm water.

nice
could i put some guppy fry in there too or no
they are there temporarily maybe i can make a system with those big 40gal tubs
or a emerse plant system
 
You can have guppy fry in with the duckweed. I would increase the water depth (height) if you add fish.
