Do you think a 700w light is too much for the seed...

Do you think a 700w light is too much for the seedling stage? I want to make sure she receives adequate light without frying her.

Yes and no... all depends on the setup.
10" hang height at 100% = yes death
120" hang height at 100% = no? maybe
20" hang height at 20% = mot likely fine
Most manufactures give you some basic hang heights and intensity settings for stages of life like seedlings. veg, bloom. They almost all suggest a hang height of somewhere between 12-20" for the most even lighting map with minimal hot spots.
How long the light is on, its intensity and hang height all go into determining how "strong" the light is. 700w is a lot of wattage. but so is 200w if its much closer and on longer.
Look up the term DLI and PPFD. get to know them. Your DLI is the best metric to measure your lighting needs. When I found mine, I realized I was cooking my plants with to much light.I needed to drop down my cycles from 18/6 to 16/8 and adjust its hang height to 30 inches. It has been said the upper limit is 40DLI, I am for 35-37 as the closer they grow to the light. the more the DLI increases.

if the light hung to focus on 2 square meters full of seedlings, it might be fine, lol.
Lol, is this a troll asking a question?
LED or HID would make a difference too as far as area of coverage, but both would be too much for seedlings in most cases except commercial scale production.

Get Photon app,
dimm your light to 150 ppfd the first week, second 300. If your light is not dimmable, you can hang it up to get the right ppfd.

Lade dir eine App zur Lichtmessung auf dein Handy. (Z.b. Photone)
Damit kannst du sehr gut die ankommende Lichtmenge an der Pflanzenspitze messen und dann die Lampe passend einstellen. Pauschal kann man mit „700Watt“ nix anfangen, lampenart, Hersteller etc haben großen Einfluss auf die Leistung. Grundsätzlich sind die sehr empfindlich die ersten Tage, vor allem bei so langem (18h) ununterbrochenem künstlichem Sonnenschein. Teste dich vorsichtig ran, schreib dir bestenfalls die Werte mit (beim nächsten Grow brauchst du die Werte ja wieder) und beobachte die Pflanze gut. Sobald sie zu wenig Licht bekommt, fängt sie an sich zu strecken. Dann solltest du auf jeden Fall etwas mehr Licht geben. Zu viel Licht erkennt man an den heller bzw. gelb werdenden Trieben am lichtnächsten Punkt.

Turn down the Power on the light of its possible or start the seedling with a small led light

Hey bro, it really depends on your setup, a 700w light can be fine if it’s dimmable or hung high enough, but straight at full blast is way too much for a seedling.
For early seedling stage:
Dim to ~25–30% if possible
Or hang it 80–100cm (30–40") above the seedling
Watch for signs: praying is good, tacoing or bleaching = too much
You’re aiming for gentle light to encourage roots, they don’t need heavy PAR until after the first set of true leaves. Less is more early on.
✌️ Keep it light and let her build a solid base first.

Definitely a lot of wattage for a seedling, she can only use so much of what shes getting, everything over what she needs or uses is overkill, coupd cause stress, exhaustion or or even overheat

Seedlings really don’t need too much early on, check the manual with the light - they usually put dimming settings for seedling stage in there. If you can’t dim the lamp then make sure it’s quite a way up from the seedling.
Hope this helps
