i think, firstly your bulb is really poor, 30 watt halojen gives almost 600 lumen, am i wrong, it is so poor, and also i dont think so your bulb is halojen, it seems cfl. but also poor again. and you can up the tempeture 25c
this is can be helpfull, https://www.rollitup.org/indoor-growing/53600-average-distance-between-light-plant.html my idea is: it is the best keep closer as posibble you can, and offcourse you must control the heat
--he will be fine-- :) i hope she will be better, i read about the general tropical plants, it says they must take at least 5 hours DIRECT sunlight, so you can be more carefully abaut the shadow maybe
good idea to put the little ones in a white place like yours. i am also new at growing and i have similer problem with english :) plants look ok for me. good luck.
Average distance between light and plant tops *Fluorescent-T5HO- any wattage - 3cm to 10cm /*HPS 400w - 30cm to 40cm /*HPS 600w - 50cm to 60cm /*HPS 1000w - 70cm to 80cm
And, there is lux thing, lux mean again light power calculation thing. real :) sunlight on an average day ranges from 32 000 to 100 000 lux. i guess, i have 22.500 lux power at home on the plants, so it is difficult to catch real :) sun's power
forget about the -like a 60w bulb thing- good way to talk about just 13w cfl and lumen power for example i have a cfl, which is 60w and its power 55 lumen per a watt so it gives me 3300 lumen, -and it is 6500k (daylight)- .i take these lightpower at home: one 400 watt hps -55000 lumen, several...
