Once seeds sprout, they need light. Just be careful not to burn them with too much too fast.
I start feeding when they get there first true leaves.

I agree that they need light once they sprout. I put lights over the trays of sprouting seeds.

I'm not sure what benefit you're going to get from the greenhouse in a tropical environment.

You can't up-size net pots later in a plant's life, so start it in the net pot that it will have for the duration of its life. You can use a rockwool cube in a net pot of hydroton pebbles to start the seed, or just the rockwool itself. There are also other seed-starting mediums now available that do the same thing as rockwool.

thanks nil13 & Cole R.

the greenhouse is mainly for preventing he rain from washing away the nutrient solution and protecting the plants from wind and heavy rain, but it is nothing fancy

thanks for the info

depending on the plants grown and type of system, you frequently won't need anything larger than 2" netpots.
Also, a well sealed system can prevent a good bit of the rain from entering your system so you could potentially grow them outdoors and not have to deal with the heat buildup greenhouses present. Though you will have to get adept at modifying your nutrients to maintain the concentration.

thnaks grizzman.

Im having 10 bato buckets with tomatoes, bell pepper and pepino on a drip system, then a ebb&flow grow bed for the herbs: basil cilantro, parsley, celery and maybe lettuce although I'm thinking on having lettuce alone on the side of the grow bed on a DWC system.

my plan is to have small pvc grenhouse, and keep the door open if it gets too hot, but maybe it is a bit of a overkill and I'd get away with some sort of roof thingy. I'll get to that when i get some decent seedlings =)

about the seedlings, once they sprout I putting them outside in the morning to get some sunlight but with shaded cloth on top, they are getting about 2-3 hours of morning sunlight, after this I guess they still get some light but is not direct sunlight anymore but is more under shadow of the house. is this ok? (picture attached of a pair of a 2 week pepino seedlings)

thanks again.

That sounds fine. they don't need a whole lot of adjusting to the sun. perhaps a week to adjust.
a greenhouse with just an open door will probably still be too hot. I've been in them here (~35ð lat.)in the summer with doors open and the temperature is still 20ðF hotter than outside. just bear that in mind.
Will your drip and EnF systems run out of the same reservoir? Tomatoes can generally take a much stronger nutrient than herbs so either you suffer leaf burn on the herbs or the tomatoes grow more slowly.

separate reservoirs for each system, I realized that they are on a different feeding diet by reading this forum :D

thanks for your help.
